Tess Gerritsen is onto another sure winner here with "I Know A Secret" the 12th in the Rizzoli and Isles thrillers!
You can read this as part of the whole series (recommended) or as a standalone novel (also recommended) but you won't be disappointed either way as this is a cracking book that has a fantastic storyline, is easy to follow and will have you flipping the pages as quickly as you can turn them.

Before you take a peek inside the book, take time to savour that beautiful cover ( I absolutely love it ) and whilst a cover does not indicate a great read, fear not, because the storyline certainly lives up to this alluring work of art.

Homicide Detective Jane Rizzoli, and Medical Examiner Maura Isles are back for the twelfth instalment of this ever popular series from Tess Gerritsen.

The opening chapter takes us straight to the crime scene of a horror film producer found dead in her apartment.

This is the twelfth book in the Rizzoli & Isles Series. This is one of my favorite series. I have read every book in this series and Tess Gerritsen does not disappoint. I loved every book in this series and I was so ecstatic when I received this copy of the book. This book was the bomb! It just rocked. I just loved it. This book is filled with suspense and rich in character development for characters we have come to know and love over the course of the Rizzoli and Isles series, this book is a t

Fantastic addition to the series!

Detective Jane Rizzoli and colleague, Medical Examiner Maura Isles are once again called into action. This being the 12th installment of the highly successful series. So successful in fact, it’s become a long running TV series. (Might be cancelled now?) Though I must confess I’ve never watched it. I much prefer reading the books.

So away we go! The first victim is found in her own bedroom with her eyeballs in her hand (ewww!). The second victim has 3 arrows straig

I have watched the television show featuring these two women, off and on. Enjoyed the actresses who played Maura and Jane. It also added to my reading enjoyment, since now I picture these two in my head, while reading the novel. Like a episode of the teller show playing in my head. Luckily I did like them because ever since Tom Cruise has played the lead in Lee Child's books, I can no longer read them, and they had been among some of my favorite reads. I apparently have a very strong, pictorial ...more

Returning with the twelfth novel in her popular series, Tess Gerritsen shows that she is still able to captivate audiences with her Rizzoli and Isles police procedurals. When the body of Cassandra Coyle is discovered, her eyes surgically removed, Detective Jane Rizzoli is concerns that there is a new and sadistic killer on the loose. The detail of the bilateral globe enucleation has even Dr. Maura Isles baffled, especially with no real clues as to who the killer might be. When another body is di ...more

I know this was a good read because I finished it in one afternoon and evening! It was too interesting to put down!

I enjoyed the way the book was written from different POVs as it was nice to get into the head of one of the key players as well as knowing what Maura and Jane were thinking. I was a little annoyed that no one thought to look at the victim's pasts as the school link seemed pretty obvious to me, but that is only a tiny criticism.

This is my first Rizzoli and Isles book, and I thoroughly enjoyed it. I have seen a few episodes of the tv show, so in my head I'm picturing those two characters as the talented and lovely actresses who portrayed them. It really added something to the experience of the book, the ability to picture them so vividly. I Know a Secret absolutely works as a standalone. It's quite impressive how the author fills you in on little details of the history of the characters without doing it in an overly obv ...more
‘This guy was so clean he would’ve squeaked.’

‘Or so everyone believes.’

Jane shrugged. ‘You never know what the truth is.’ Every human being had secrets, and too often it was Maura who uncovered them: The upstanding citizen found dead with child porn clutched in his lifeless hand. Or the perfect society wife with the syringe of heroin and a needle still embedded in her arm.

Despite some thrillingly gory deaths inventively used, this book felt formulaic and lacked any real tension. The family drama was all stuff we'd seen before and the main plot, while having a solid foundation in the mix of child abuse scandals, moral panic, and psychological testing, failed to live up to its promise thanks to the hugely unsurprising and unsatisfying ending.

It's good enough to fill a few hours, but it's not her best, and I wouldn't rush out to get it.

When medical examiner Maura Isles was called to the murder site, homicide detective Jane Rizzoli was already on the scene. She was pale and Detective Frost, Jane’s partner looked ashen. The sight of the young woman, lying as though peacefully sleeping was only broken by one thing – and that was horrifying…

When the autopsy was conducted, Maura could find no cause of death – and her puzzlement was to continue with a second victim discovered only a few days later. His staged body was decidedly grim

This is the 12th full length novel in the popular Rizzoli and Isles series by author Tess Gerritsen. I enjoy both the novels and the TV series but although there are a lot of similarities the books in my opinion are so much better. Like most series the more you read the more familiar you get with the characters and 'Rizzoli and Isles books are no different, each character is so much more interesting once you get used to their manerisms.

Homicide Detective Jane Rizzoli and Medical Examiner Maura Isles are called to a gruesome murder site of a horror movie filmmaker. As they consider whether they’re looking at life mimicking art, another murder occurs where Maura makes the unusual connection to the first scene. And, the connection between the victims leads them to a notorious case dating back twenty years.

Imagine the exhilaration I felt when I noticed on Goodreads that a new installment of the Rizzoli & Isles series was due to get published this summer, considering that I have said countless times that Tess Gerritsen is one of my favourite contemporary authors of mystery/thriller. The Rizzoli & Isles novel series also served as a source of inspiration to the popular TNT police procedural and crime drama starring the talented Angie Harmon and Sasha Alexander, which, sadly, concluded last year.

Tess Gerritsen writes her characters very well. I would think sociopathy comes in varying degrees, and as you read this book, you will know which characters I’m talking about. The two main characters, Jane Rizzoli and Maura Isles, are true to form as they have been in previous books. Even Jane's family is still in turmoil. Maura's life just might be on the verge of a major change. For the life of me, though, I can’t recall which bits of history are in previous books or from the television show.

Who is this person, this narrator who in the opening chapter of Tess Gerritsen’s I Know a Secret lists funerals she has attended? She states that she does not cry at funerals, even though she somehow knows that is what is “normal” behavior. That first funeral was for an uncle, whom she barely liked, but she was there because she was only seven, and her mother required her to attend. Later, as a young adult, we see her attend other funerals. Who are these dearly departed, and what is this nar ...more

I can’t believe there is any avid crime reader out there who has not yet dipped into the Rizzoli and Isles series from Tess Gerritsen but if that is you then you might want to take a look – I have yet to read one that disappointed me (and I’ve read them all sometimes more than once) right from way back when “The Surgeon” was published.

The two main characters have such a fascinating story arc throughout the series (maintained and intriguingly expanded once again here) and in “I Know a Secret” the

This is book 12 in the Rizzoli and Isles series. The book starts with a first person woman narrator who is cold and manipulative. Then it switches to a scene with Maura Isles and her dying mother. The third chapter has Detective Jane Rizzoli and Doctor Isles at a gruesome murder site. These three threads do come together in a very satisfying mystery that I devoured in two days. There are enough twists and turns in the plot to keep you interested until the end.

This is the twelfth book in the Rizzoli and Isles series and I have read everyone of them and enjoyed them all. They have also been made into a T.V. series. I have not watched the T.V. Series as I find it spoils the books for me. I like to have the plot unfold in my head and have my own version of the characters, plot etc.

Tess Gerritsin is one of those authors who have never failed to impress me. Whether it's a stand-alone or Rizzoli and Isles. I must confess that I stopped reading her books back around R&Z #7. Only because I loved the show so much that I decided I needed to pick either books or t.v., the show won because I do love me some Angie Harmon. Then I quit watching television altogether, and Tess fell by the wayside. I'm back! This story left me guessing whodunit. I usually pick up on it, but not this ti ...more

This book won't be released till Aug. 15, but I was way too excited about the opportunity to read an advance review copy that I just couldn't wait to read it. That's because the author's "Rizzoli & Isles" series has been a favorite from the start (for the record, this is the 12th). While this one somehow seems a bit darker than most of the others I've read, it's no less well written.

I have been reading Tess Gerritsen’s “Rizzoli & Isles” mystery series for long time, even before the television show starting airing. I have watched the show and enjoyed it; however, I have always liked the books much better. There is a darker tone and more focus on suspense surrounding the procedural work of solving crimes. I enjoy the strong friendship between the two main characters – detective Jane Rizzoli, and medical examiner Maura Isles – and their related family situations. I also apprec ...more

Let me tell you a secret; it was a few days after Christmas, the busyness was over, the fridge was full of leftovers and all the visitors had returned home, the house was quiet.

Actual rating 3,5 stars!

The books by Tess Gerritsen are one of the only murder mysteries/thrillers I follow. After a while I think this genre books really blends together and I don’t enjoy them anymore. But I love the books by Tess Gerritsen, I love that it follows the same characters throughout the books and that you can see them grow and make more connections and get children, build relationships etc. I also love her books because of the scientific approach she always takes on them.

This is a Rizzoli (Boston PD Detective) and Isles (medical examiner) suspense thriller and it does not fail to impress. The story sucks you right in and takes you in different directions; it’s good reading!

I've been with this series from the beginning with The Surgeon, and I appreciate how the author always comes up with clever, interesting plots involving Jane and Maura and the crew. I am not sure if this is the final book in the series, but if it is, it does tie up some loose ends and feels complete.

I wasn't totally surprised at the villain, it's pretty obvious from the beginning I thought. But the "why" of everything is what makes this story shine and shows me what a creative writer Gerritsen i
