Proof
From a writer and executive producer of Suits comes a riveting and gritty legal thriller about murder, cover-ups, redemption, and Los Angeles—perfect for fans of #1 bestselling authors John Grisham and Scott Turow.
As a disgraced lawyer with a drinking problem that he doesn’t view as a problem, Jake West is coasting on what’s left of his charm and money. He used to be the kind of lawyer who could convince anyone of anything—until he decided to take on his father’s biggest client and prove his dad was corrupt. Now Jake finds himself almost at rock bottom, and that’s before his ex-best friend is murdered and Jake is accused of the crime.
In a desperate bid to save himself, Jake must sober up and search for the real killer, whom he suspects might be hidden in one of the case files of his father’s illustrious law firm. As he delves into a labyrinth of lies and corruption, Jake teams up with an eclectic group of equally broken people as they all must skirt the law in order to find the proof he needs…no matter the personal or professional cost.

It would appear Jake West’s life is unraveling. A partner in his father’s law firm, but seemingly resigned to living in his shadow, having failed to meet his expectations. He’s now estranged from his wife and children, finding solace at the bottom of a bottle.
And today things are about to go from bad to worse when his friend and colleague is murdered, and Jake becomes the number one suspect!
Not only does Jake need to clear his name, but he owes it to his good friend to find the real killer. He enlists a motley group to assist, including (shockingly) the police detective investigating him!
This is a debut legal thriller that was extremely entertaining! The emphasis is not directly in the courtroom, but on the characters themselves as they work together to solve the crime.
There were a lot of characters, but all the main players were very well developed and I instantly had a connection with them.
I’m hoping this is just the beginning of a new series. I grew fond of Jake and his crew and would definitely want to see them again..

I’ve just learned from the author that this is the first in a series, so be sure to grab it now as you don’t want to miss out on this out-and-out winner!
Taut, complex, and propulsive in the extreme, Proof felt like The Firm only better. You see, while the latter had Tom Cruise, the former had Jake West in all of his root-for-able glory. Lionhearted yet also genuinely flawed, his character arc over the course of the novel was a huge part of what made this book sing. That’s not to say that the plot wasn’t also simply divine. Fast-paced, twisty, and the epitome of legal thriller perfection, I was utterly spellbound from the quick-off-the-mark start until the flawless conclusion. Now I’m just crossing my fingers and toes that what I just finished reading is only the start of a series. After all, this motley crew of characters are crying out for further adventures, stating with what happened in Ireland.
Speaking of those characters, from the endearing albeit disbarred PI to the smart, head-turning assistant, this white-hatted bunch was fictional perfection as they helped Jake with his newest cause. Told via multiple POVs as well as plenty of flashbacks, they all felt true-to-life as well as fully fleshed out. That’s not all that surprising considering Mr. Cowan was a writer and executive producer on the hit legal show, Suits, but it was the plot that grabbed me and didn’t let go the most. Packed full of murder, cover-ups, and some much needed redemption, it kept me guessing throughout as I raced through the pages of this intense, gritty tale. Bravo, Mr. Cowan, you’ve got yourself a new fan!
My only irritation, if you can call it that, was the lack of any significant courtroom drama. Were there a few scenes that had me utterly rapt? Sure…but I would’ve loved more. After all, they were both attention-grabbing and well-written. Like I said, though, it wasn’t really a flaw all things considered.
All said and done, with no shortage of morally gray characters or out-and-out villains, I was kept guessing as I side-eyed almost everyone with utter suspicion. A debut sure to knock any legal thriller lover’s socks off, I was blown away by every piece of this novel. With witty dialogue, hypnotic storytelling, and enough moral dilemmas to make my head spin, I just couldn’t put this book down despite real life calling for my attention. After all, the cinematic feel and evocative setting brought to life LA as if I was watching it on a screen. But it was the underlying mystery that kept me firmly in suspense from beginning to end. Point blank? I can’t recommend this unputdownable thrill ride more if I tried. Rating of 4.5 stars.

✰ 3 stars ✰
An issue I've always faced when it comes to screenwriters turned authors is that their writing tends to read as if it was meant with a screen adaptation in mind, rather than for the reader to visualize it for themselves. As in the interactions, the chain of events all unfold in a way that is aimed to be brought to life with more swiftness, rather than having it play out in words. 🎬
Do you get what I mean? It read like a Pilot that needed to cover all the necessary players to set the stage. 😮💨 I could feel that the extensive character profiles into their backgrounds, layering out the setting and scenes had more of than intent, rather than having me immerse myself into the actual plot. which is fine and fair. and it makes sense when I read the author is already hard at work at Jake West's next mystery.
I'm also wondering why he poked fun/alluded to most lawyer films rather than the tv shows he's actually worked in irl? Conflict of interest? Legal liability?? Shame the films were the only ones I had actually seen! 🙈
“Who among us wants to be judged on what we’ve done?”
The legal aspect was full frontal at its finest. Well, my range only comes from the movies he did refer to. One reference was so Legally Blonde, I couldn't help but laugh. I wonder why most legal thrillers' action happens out of the courtroom, rather than playing out their wits on the stand. well, in 41yo Jake's case anyway.
As much as he is your typical white, down-on his luck and vibe kind of protagonist, drinking his talents away to a stupor with an obvious daddy chip on his shoulder, it's difficult not to root for them. he's likeable, smart, charming, and he'll get the girl -- or does he?? 🥺
Ofc, it's always fun to see good triumph over evil, the poor outsmarting the rich, the bad guys brought to justice for their corruption. Even with danger and threats nipping at his heels, conspiracy theories afoot with rich people with too much money and time on their hands plotting his downfall to cover up their dirty tracks, it's an all-too familiar beat, but still you can't help but be swayed by it. 🫡
You see his own character shaping into a better one, fortifying his own connections and building bridges that will strengthen his own future conviction and resolve that he had somehow lost along the way. 🙆🏻♀️ It brings back his love for being a lawyer, what his purpose and intent should have always been.
“—where’s the challenge if it’s not a losing battle?”
My biggest gripe is that it was just too slow-moving. It's the forgetting that events on screen move faster than in writing; the details are visually represented whereas here words take up a lot more space. And for that, it really slowed down the pace and made the multi-perspectives less immersive and hard to stay entirely focused on.
I loved the cold opening. It blew my mind - literally and immediately hooks you. 👍🏻 And after that, it carried the human element to make Jake's motivation and gumption in righting the wrong more convincing. The niggle that something is amiss, an evidence that's escaped the rightful lead, the Proof needed to solve a puzzle. It's a gratifying feeling to have the actual truth come to light. 💡
Even if it followed a predictable flow, a lot of dynamics were fun to watch. If I had also known it was to be the start of a series, I may have reconsidered ploughing in. But, along the way, I began to -- not care, but enjoy the different engagements and how each character found their own footing for themselves.
My favorite banter and interactions were between Jake and Siobhan, really solid repartee and believable chemistry. 😌 I'll be curious to see how and if Jon Cowan will shift the scene from the glitzy glitter of L.A to a more toned down one, where some unsolved mysteries might receive their due closure. It'll be interesting to see how their change of opinions of certain views and of each other will play a part in the next crime afoot.

Jake is a disgraced lawyer, an alcoholic, and man whose life is falling apart. He is a difficult character who grows on you over time. I started out finding him insufferable but as he became more self-aware and grew a conscious, I began to root for him and saw him as that friend that you have a blast hanging out with but can only handle them in doses. I thought the side characters paired well with Jake and played off his personality in an engaging way. There are many POVs and each had distinct voices.
There are multiple veins to the story, starting with the murder of Jake’s colleague and friend, and then expanding and linking to multiple other crimes. Jake is the main suspect in the murder and to clear his name, he must investigate and find who really killed his friend and how it’s related to other recent events connected to his firm. I enjoyed the ride of figuring out the connections and finding the truth.
I found many similarities with characters, backstories and side stories, and overarching themes to The Lincoln Lawyer series which sometimes made it difficult not to compare the two.
This is Cowan’s debut novel, and I’m excited to see what he writes next.
I received an advanced copy through Netgalley in return for an honest review.

A fun legal thriller with a flawed main character that grows on you over time. Jake West is living in his father’s shadow and a persuasive but morally grey husband and father. He flirts with sobriety and fidelity, but when push comes to shove, he will put justice and the truth ahead of greed or selfishness. His best friend is killed right next to him and he is the main suspect. The next day he goes to a deposition for a plea deal which really seems like a gift— a cushy deal for a young mom, Tiana, who lost her roommate and then her 2 young children in a fire that she is accused of starting.
Something about it just doesn’t sit well with Jake; so he engages his semi-ally Sioban (not Siobhan) to find out if this is related to his friend’s murder.
Multiple POV and different circumstances, I give this book a 4/5 for dialogue, a 3/5 for story, and a 4.5/5 for characterization. It’s slightly too long and convoluted, but I am truly impressed for how I found myself detesting Jake at the beginning to rooting for him at its conclusion.
This is a debut novel from an experienced screenwriter- he is going to publish more in this series. If you enjoy legal thrillers, this is a great new voice in this genre.

An intellectual legal thriller that has great mystery without the usual thrills and scares that accompany a thriller. It starts out with a bang and continues to deliver the mystery and twists throughout the entire story.
This has phenomenal character development that quickly pulls you in. My feelings towards different characters drastically changed from the beginning to the end.
This was a bit long and dragged on at parts, but I enjoyed the story enough to still be intrigued enough to continue picking it up. A great debut by Jon Cowan!

Jon Cowan’s Proof hurtles forward with the same irresistible momentum that made Suits such a binge-watch phenomenon—yet he resists the urge to cut corners. The early chapters take their time laying down Jake West’s shattered world, and while that measured build-up may feel leisurely at first, it pays off in spades. Once the action ignites, you won’t be able to look away.

Loved this book! It was the perfect legal thriller that kept me engaged page after page trying to figure out “who did it” and why.” The main character, Jake, did not always make the best decisions, but I found myself rooting for his success. Definitely hope there will be a sequel!
September 2, 2025
Pretty fun! A few obvious tropes and a few too many things pulled directly from Suits but hey when you write Suits I guess you can use it in your book too.

A fast pace thriller that’s also a bit of legal thriller with a flawed MC, Jake West, an attorney battling his drinking problem. As a main character Jake put me in doubt, at first, well you know the type. Well, turns out he’s not that bad. Jake is capable and smart when he’s not drunk but even when drunk he is quite funny and not a total fool or ass. I think he’s more a functional alcoholic than many main characters I’ve read so far that’s why his character gradually grow on me. His ragtag team is also very interesting and entertaining. They are all flawed but they are such a well developed characters and a cheer-on worthy team when sticking together. I would love to see them in a legal thriller…that would be so much fun.

2.5 and I’m rounding up. This was simply fine, an easy read. The characters lacked depth and it read like a screen play. I think some would like it, gives a similar vibe to suits. Wouldn’t read again, maybe would recommend for the right person.
May 7, 2025
I really liked the main character, Jake West. He’s smart, witty, and isn’t afraid to stand up for what’s right. I like how the story had different stories going for people who were done wrong. Then it all came together in the end. I’d certainly recommend this book and would read other books by this author.
July 1, 2025
So I wanted to like it and I actually finished it which is a lot for a two star review. The characters were fine though a little cliché, but they kept me reading till the end. But the plot was ridiculous and it’s supposed to be a legal thriller that in theory would have a somewhat plausible plot. No, don’t expect that here.
December 7, 2025
Satisfying, fun read. Hoping he writes a sequel to this, which given the ending seems likely.

Thanks to Gallery Books for the gifted copy. All opinions below are my own.
This one is a non-stop cat and mouse game between a lawyer and an unseen force that is trying to frame him for the murder of his best friend. But why? Jake is down on his luck, he's recently divorced, recovering from a judicial scandal, rarely sober and now reeling from the grief of loss. He's spent his life chasing his father's approval only to find out that his father's firm may be behind his precipitous fall. He teams up with his best friend, a recently disbarred lawyer, and a paralegal he cheated on his wife with to try to clear his name and finds himself embroiled in a conspiracy bigger than he could have imagined.
I'm mostly over the 'down on his luck' lawyer types, but I found myself liking Jake more and more as the story went on. The inciting incident in this one is really crazy and you definitely don't want to put it down once you figure out the web Jake is tangled in. It ends up a lot more complex than you'd think and reads a bit like a spy novel.
If you like Grisham or Turow this one is for you.

A Fun Debut
I really love main characters who are flawed but deep down they try to do the right thing. Jake is a disgraced lawyer with a drinking problem. He’s an absolute mess and it took me a while to like him. He grew on me though and I started rooting for him! By the end, I loved him and I was hoping this might turn into a series so I can read more books with him and maybe Sioban! There’s a lot of great characters in this though. I loved how they worked together and had each other’s back.
This book was not only interesting to slowly figure out what happened but also interesting to see how corrupt the legal system can be.
Fair warning: If you don’t like books that
switch between multiple POVs then this isn’t for you but it was fun legal thriller.
Congrats to the author on their debut. I look forward to reading future books by them. 😊

Full of surprises, PROOF, was an entertaining legal thriller. I found myself rooting for Jake, an alcoholic, disgraced lawyer, to clear his name after being accused of murder.
There are many, many names to keep track of, which did detract from the story somewhat, but all in all, this is a fantastic book. There were enough clever plot twists to keep me entertained. This is a solid 4-star read.

This book is hard to explain for me. I really enjoyed the characters and felt they were all well developed, but the writing was so strange. The perspective shifted so quickly from one character to the next, even amidst a paragraph, and it felt poorly written because of that. It must be a style of writing? It just didn’t seem like a story should be written so jumbled like that. One minute it would be from Jake’s perspective and then it would jump into the mind of who he was talking to and it felt confusing at times.
It took me a while to read and although all the events were good and made you truly question who was behind it, it seemed to sort of drag on and felt confusing at times. I wanted to love this one!
Also very much resembled characters in Suits!

What a ride with this investigative thriller…Jake, a drunk lawyer from a prestigious law firm is trying to get his wife and children back, witnesses a murder of his best friend and off we gooooooo. The police, Jake’s friends, the District Attorney, lawyers from “the firm”, corruption, murder and a good couple of twists make this book flow! Enjoy

I found this to be highly enjoyable… a nice blend of murder mystery (kind of) and (suspend your belief) lawyer drama. I thought the characters were engaging and the story was detailed enough without being too much. The epilogue was unnecessary (in line with my general opinion on epilogues), but overall well written and fun! This was written by an Executive Producer of Suits, and I could definitely see the drama and plot line of this book being in that same arena.

This was probably a good legal thriller. I simply was not in the mood for another close-to-disbarred-attorney-throwing-away-his-family-wife-kids-and-drink-too-much-get-charged-with-murder-instead-and-have-affair-with-office-staff-but-yes-by-golly-there-is-one-more-case-of-big-bad-wealthy-guys-stomping-on-little-guys-who-he-is-determined-to-defend ... trumpets blaring, I'm sure🤦♀️
Nuff said.😊

It was ok. The anti-lawyer rhetoric grew tiresome.

This was a high stakes legal thriller that began fast and never let up. It kept me guessing until the end.

Grisham/Turow knockoff clearly not written by a lawyer.

Intriguing legal thriller. Jake West works in a prestigious LA law firm begun by his father and associates. His relationship with his dad has never been warm and fuzzy, which may have been part of what led Jake to turn to drinking. Now he's estranged from his wife and kids, too. One evening, his ex-best friend picks him up when he's too tipsy to drive and, before they can head off, someone shoots and kills his friend in the seat beside him. Jake is accused of murder but out on bail. While trying to clear his name he stumbles upon a hornets' nest of bad behavior at his law firm and discovers just what kind of person his father really is. He must work to save not only his career, but also his life and the lives of those he cares about. Fast read.

I had a hard time paying attention to this one…

2.5 stars. There were so many characters and I didn't care about any of them. No matter how many times the author said that everyone loved Jake, I wasn't feeling it.

Jon Cowan brings readers PROOF, a taut legal thriller, drawing on his cinematic skills he honed as a writer for the hit television series “Suits.” It starts off with a bang and ratchets up the tension from there.
As the partner of a prestigious law firm, one holds a great deal of power in Los Angeles. But beware the power struggles within; they have a way of revealing secrets best left buried. It’s a cutthroat world at Thompson & West.
When the story opens, Jake West is presenting a closing argument. Sure, he’s had a few drinks. He’s not drunk, though; just ask him. He’s only having a little fun, playing lawyer...which he’s well suited for because, well, he’s a lawyer. But he’s arguing in front of a nonexistent jury. At night, in a closed courtroom. All because he wants to impress a lady. This, of course, is a problem. Jake’s dad, Norman West --- of Thompson & West --- sends Rich Kaplan, one of the firm’s associates and Jake’s one-time friend, to rescue him from getting himself in a heap of trouble.
Jake gets into Rich’s car, and they’re about to pull away from the courthouse curb when a bullet blows Rich’s head off. What happens after that is a blur to Jake, although he does remember picking up the gun that just killed Rich and seeing a man in a hoodie running away. He tells the police all of this, but the detective on the case, Sioban McFadden, finds his story totally lacking in credibility and entirely unbelievable. Jake understands. It looks bad. Worse, his position at the law firm is shaky at best. He blew a case last year, which led to a censure. His drinking caught him up in a brief affair, which led to his wife leaving him. And now he was in the wrong place at the wrong time, which led to him being accused of murder. Frankly, Jake’s life is a mess.
In what may be a rash move --- when did he not make a rash move? --- Jake insists that he take over Rich’s caseload. His demand is begrudgingly granted, but not without heavy pushback. When he sees the first case, he only has time to rush to court immediately. They’ve told him it’s a slam dunk --- a simple plea deal. Everything has been worked out. Just show up and sign off. Except Jake doesn’t work like that. And he smells something rotten. The deal is too good, the DA is too eager, and even the judge seems to want this case to disappear fast. So Jake drags his feet, which makes everyone unhappy --- so unhappy, in fact, that it begins to smell even more. And when he barely digs under the surface, he uncovers more than a few reasons to be suspicious. That’s when things turn deadly.
By now, Jake’s new client trusts him, at least sort of. And Detective McFadden is beginning to like him, sort of. His dad, though, would rather sever ties --- and does. Why is that? Norman West has never been a warm and fuzzy father, but his recent behavior makes Jake believe he’s really on to something. Something worth killing for.
PROOF will knock your socks off if you’re a fan of John Grisham, Scott Turow, David Baldacci or Michael Connelly. Jon Cowan is a new sensation in the legal thriller genre and even kicks it up a notch. And Jake West is a brilliant screw-up but so totally likable that one can only hope there’s a series in the making here.

A bankable director since DIE HARD and THE HUNT FOR RED OCTOBER, John McTiernan teamed with a former bankable Bond man to return to the cozy jungles of PREDATOR, this time not hunting an alien species hunting man, but searching for a cure against THE deadly disease hunting all of mankind. Shipped with an awesome trailer and ad campaign, MEDICINE MAN nonetheless failed to sway the box office jury in early 1992. Dipping into MEDICINE MAN's theme that "a miracle without proof is only a miracle," PROOF's Mason Winter needs exactly that. A bona fide officer of the court and upstanding member of the community, he's the prime suspect in his friend's murder and he doesn't have a prayer. He did, however, pass the bar.
Fifteen years out of law school, Jake West works for the family business but still hasn't shed the post-college rebel attitude. Rumpled hair and wrinkled suit is the everyday look, even though he enjoys being the center of attention and is rumored to being able to persuade anyone to do anything. Daddy's name on the letterhead is a significant problem, though with his besties Glen, Peppy, and Scotch, Jake tries hard to forget it. When his best friend who caught his wife on the rebound is killed, Jakes becomes suspect Numero Uno, seeing a dastard wrong that needs righting. Digging into his friend's murder is the best way for Jake to dig into his daddy issues, and he loves a good conspiracy theory. But it's a big city out there and a lot of dirty deeds go down. Sometimes, it's Jake and his legal brethren's jobs to clean it up. After all, what Jake and everyone wants is truth, justice, and equity. In formidable fashion of Gino Felino, Jake is OUT FOR JUSTICE and won't rest until he finds out who killed Richie and clear his name, looking for PROOF one step at a time.
A solid yarn about redemption, PROOF is where BACKDRAFT meets THE FIRM, a book that also points out how easily one can be erased in the modern world. Featuring a solid shoutout to A FEW GOOD MEN, PROOF boldly states that the legal system is corrupt and broken, hope is dangerous, to never let the client get the upper hand, that everyone has an agenda, some cases you just can't win, that there's doing what's legal and what's right and sequence does not make causation. Less Grisham and big conspiracy, PROOF is more just people being what they are--self-serving and self-interested. Though PROOF is definitely not a low rent or TEMU Grisham thriller. PROOF is legit entertainment and as good as early Grisham or Turow. Whereas Grisham is succinct and maybe a tad formulaic, the proceedings in PROOF, character development and problems at times seem a bit much; it's too dense and too much drama. With more politics, corruption and backroom deals than Chicago in an election year, PROOF is ultimately a story about land theft and profit, the oldest grift on the continent, all in the name of corporate greed. For AN INNOCENT MAN who thrives by playing outside the lines, PROOF is the ultimate game for truth, justice, and deliverance. Carrying on the legacy of the greats, this is the new evolution of the legal thriller and PROOF is in the pudding.
