By the end of our time together, someone in this house will be rich. Someone will be the World’s Greatest Detective. And someone, well, someone might be dead.

Detectives’ Row is full of talented investigators, but Toby Montrose isn’t one of them. He’s only an assistant at his uncle’s crime-solving business, and he’s not sure he’s even very good at that. But he sees his chan

A fun read for 10 and up. Felt like a mix off Sherlock Holmes, Agatha Christie, The Westing Game, and Clue. Sure to please a lot of junior sleuths. 😊

Sweet. I downloaded and read it because the description reminded me of The Westing Game, one of my favorite books ever. It wasn't really the same writing style, but the charm of smart children trying to solve a mystery still makes me smile.

Toby's parents were both presumed dead after a boating accident, and after bouncing from relative to relative, he has finally landed with his Uncle Gabriel, who is a detective in the early part of the 1900s. His uncle is not a tremendously successful detective, so Toby has enrolled in Inspector Webster's Detective Course, hoping to gain some skills to help his uncle take business away from the more successful Hugh Abernathy, as well as other detectives in

I thought this story was too slow, and it would have been more enjoyable if it had been significantly shorter. I did like the ending, though. It was something that I didn't expect. The characters were okay. I liked Ivy more than Toby. I thought he was too bland, not an interesting main character.

This middle grade mystery was so fun! The characters were interesting and engaging. I was kept guessing the whole time, and just when I was sure I knew the answer, there was a dramatic twist ending that I didn't see coming at all! (Of course, as this book demonstrates, sometimes children are better detectives than grown ups.) I would recommend this to any mystery-loving child 9 and up (due to the prevalence of, of course, murder and a somewhat intense scene towards the end).

Oh goodness, the WRITING and VOICE in this were glorious. This is one of my favorite types of books~ Britishy mysteries. I adored the characters and the red herrings and the outcome. Loved it!

I have found a book to recommend to our middle-grade grandchildren! Toby thinks trouble follows him, and it does seem so. When his parents go missing, he finally ends up living with his detective Uncle Gabriel who is struggling financially. Toby goes to desperate measures to win the $10,000 prize offered to the detective who can solve a staged death and then become "The World's Greatest Detective." Before the game starts, a detective is murdered. Toby and wanna-be detective Ivy join forces in th ...more

I expected to enjoy this book, and I did. I expected a slightly predicable mystery, and I was pleasantly surprised to find that this author does not underestimate children. The clues were all there, but there was so much more to the story. I stayed up until 2:00 AM finishing the book because the characters mattered to me and I knew I wouldn't be able to sleep until their story was resolved.

My daughter has read (and loves) Carlson's pirate series. It is now on my must read list.

I am not one who usually goes for a detective book, but I am glad I read this book it came in my daughters owlcrate jr box. I really enjoyed it, it has a good mystery, two smart kids who are detectives and a twist in the middle.

I would give this a 3+ as it was slow to get going but the end was good and I hope there are more stories about Toby and Ivy.

Such a delightful read! I (very) often read mysteries and crime fiction, and have an affinity for Sherlock Holmes. That said, I sometimes seek out lighter fare in between weightier novels, and this was the perfect palate cleanser. Caroline Carlson has crafted a twisty, fun book for younger readers that also undoubtedly appeals to adults. Abernathy is the entitled "World's Greatest Detective," and I wasn't disappointed by his skills. I flew through this novel because I had to know how Toby was go ...more

Witty and satisfying! I was expecting a fun adventure, but the story had a layer of emotional depth I wasn't expecting but really enjoyed. Ready for the next one.

Delightful! Ten-year-old Toby Montrose has been passed around homes ever since his parents disappeared. He’s currently staying on Detectives’ Row with his uncle and fears that if something goes wrong, as it always seems to, he’ll finally be out of options and be sent to an orphanage. Being that his uncle is having a hard time getting business, as most of the detectives on the Row are, Toby decides to lie his way into a detective competition to win a good chunk of cash and hopefully solve all his ...more

With tonal similarities to A Series of Unfortunate Events, THE WORLD'S GREATEST DETECTIVE embraces the tension of a murder mystery while remaining a fun adventure for younger readers. Deeper still, it tells the story of a boy plagued by personified 'trouble' and concerns far beyond his young age as Toby works to find not only a murderer, but himself and his place in the world.

Oh my gosh. This book is a must read. It is so exciting and mysterious. I love how many things happened, like dead ends and capturing. Then in the last hundred pages or so, you find out everything. I couldn't believe who actually murdered who, really. This book is so exciting and I suggest it to anyone who likes mystery and surprises.

Toby Montrose is no stranger to trouble; it has dogged him since he was eight years old - and he's eleven now. So he can recognize trouble trying to slip under the door or hovering in the corners, and the bills marked past due and last notice that are arriving in his uncle's mail are sure signs of its presence. Since his parents were lost while boating, Toby has moved from one relative's care to another, and if Uncle Gabriel can't keep him, then it will be the city orphanage next. When a detecti ...more

This book was a great deal of fun in some ways, and heart-wrenching in others. If you're a fan of The Mysterious Benedict Society series by Trenton Lee Stewart, you will thoroughly enjoy this too. In brief, it's about a boy and girl (Toby and Ivy) who end up having to solve a real life murder when all they started out to do was win the huge prize for being The World's Greatest Detective.

I really like Toby. He's endearing, earnest, and frightened. He wants to do this one thing well, so that his l

Toby Montrose has been passed around from relative to relative, ever since his parents disappeared in a boating accident. Now he finds himself with his Last Relative, Uncle Gabriel, who lives on Detective's Row and has fallen on hard times.

Toby dreams of being a detective himself, and when the most famous detective, Hugh Abernathy, opens up a contest

The World's Greatest Detective was full of twists and turns and kept you on the edge of your seat. Carlson's imagination is just wonderful to have come up with such an amazing novel! This book has an old-timey mystery feel to it, and I just love that! I really love modern novels set in the vintage eras, I also enjoy mysteries, so this novel was a perfect mix of the two. I really loved the concept of Detectives' Row and the concept of the east-leaning house. I thoroughly enjoyed the novel, and th ...more

Hmm. Let’s first chat about how cute this cover is, yes? It’s quite lovely.
Now, to the actual story.
Mysteries are always a genre that I’m willing to read, but I don’t believe I’ve read many (secular) middle grade mysteries. (Besides my favorite series, The Mysterious Benedict Society. But, sadly, I am not here to fangirl and giggle over that beloved series.) This book had me curious because I though it may be similar to a game of Clue. I’m still not sure how I feel about a middle grade book inc

Toby is an assistant at his uncles detective agency, but because so many detectives are in the same area, money and clients are in short supply. Thankfully a letter arrived inviting them to a murder mystery party hosted by the World’s Greatest Detective. Others are invited as well and the whoever can solve it before the weekend is over will receive $10,000 and officially be named the World’s Greatest Detective. But soon afterwards a real murder takes place and Toby might be in more danger.

I was extremely interested in reading this as I loved Carlson's previous series (though I haven't read book three yet ::shame::). It's a cute story about a boy who wants to be a detective in a town full of detectives, including the world's greatest. When he enters a competition to be the next to hold that title, he has no idea the danger and trouble in store for him. It's an easy and quick read, with charming characters and a good sense of place (though I'm less sure of the temporal setting). I ...more
