Cam Jansen's career as a fifth-grade sleuth gets off to a fine start in her inaugural adventure, Cam Jansen and the Mystery of the Stolen Diamonds. Cam isn't a proven veteran of dozens of investigations at this point, merely a bright girl hailed for her unfailing photographic memory, but that gift is in rare form as her first case ever pops up when she's at the mall with her friend Eric. The case is challenging, convoluted enough that the police can't get to the bottom of it, but no detective o ...more

Recommends it for: parents reading with their children
Shelves: childrens, mystery, 2009
This is an interesting story about a young girl with photographic memory who solves a mystery based on her observations. She's a female version of Encyclopedia Brown of sorts.

As a mom, I don't like that the youngsters are left alone in the mall to babysit nor that they leave the area and put themselves in danger, but this is just a story.

On the other hand, I like that Cam is the lead character, providing a strong female role model for young girls. We will definitely look for other Cam Jansen s
When I was younger, perhaps nine or under, I was enamored with this series. I bought another Cam Jansen book somewhere (probably a thrift store) and read it last year. I can see why I really liked them back in the day, but now I realize that the writing is very much for a younger audience: very simple sentence structure, simple descriptions, simple dialog.

If I were to rate this Cam Jansen book (and the others) based on how I viewed them when I was younger, they would all be 4.5 to 5 stars. But I

Cam Jansen and The Mystery of the Stolen Diamonds is a story that revolves around a young girl named Cam Jansen, who has a photographic memory. Cam Janson and her friend Eric Shelton were watching Eric's baby brother, Howie, at the mall while his parents were shopping. They notice a commotion at a jewelry store that has just been robbed and see many people running out of the store before the police arrive. Using her photographic memory, Cam remembers noticing a man with a mustache and a young co ...more

I first met Cam Jansen a few years back when my son read a couple aloud to me as his reader, so I picked up a few more for him. I was impressed with the quality of the mystery for this level of reading. Starting here with the first book in the series, I'm again impressed with this mystery series for first chapter book readers. Cam (aka Jennifer) and Eric are two interesting and curious children with a lot of smarts. Cam's photographic memory is an unusual device and makes for a fun element to th ...more

The following is a confession from Stella Chen:
I've always wanted to be like Cam Jansen. Photographic memory? Heck yes! I thought I'll ace every test in school and become a detective one day. Unfortunately, that never happened so I have to rely on stupid studying to get me through school. -le sigh-

Also, please read my review of The Absent Author by Ron Roy to take a peek at my childhood and how I became The Girl That Loves Mystery Books.

Cam Jansen - The Mystery of the Stolen Diamonds is a very cute mystery chapter book! I just might have to read a couple more Cam Jansen books in the series! :) This book is about a young girl named Cam who has a photographic memory and helps solve a mystery based on her photographic memories and observations.

I think this book would be best to be read aloud to a 2nd grade class, but I could see it in 3rd or 4th grade as well. Cam Jansen - The Mystery of the Stolen Diamonds could be used as a way

I cut through the youth section of the library to pick up some reserved books and I am so glad I did. Seeing a shelf of Cam Jansen books stopped me in my tracks and transported me back to the Fairview Elementary School library. I loved Cam so much then and wished I had a photographic memory too. This was an enjoyable time capsule read and I have no shame about it! Cam is a smart role model involved in engaging problem solving and I hope kids still love reading about her. One thing I did find odd ...more

One day while waiting in the mall with a friend Eric, they see that there is a commotion at the jewelry store. They see many different people come running out of the store before the police arrive and Cam learns that the store has been robbed. Using her excellent memory, Jan recalls that immediately after hearing the alarm she saw a man with a mustache run out of the store, then a young c

I used to love reading Cam Jansen as a child. They were some of my favorite books. I had never read this one though, but found it to be just as enjoyable as the rest. Introducing these books to children would open them up to a new genre of mysteries they could look into later, as they grow into reading bigger chapter books. Another thing I like about these books is that it shows kids how they should pay attention to details. Cam, the main character, notices everything, which is how she helps sol ...more

A simple but intriguing Cam Jansen mystery with a robbery and the kidnapping of Cam, and the author does a fine job concealing the identity of the actual jewel thief until the ending. Contrary to the blurb’s poor wording, Cam catches the robbers; she doesn’t "frame" them, unless the author was trying to be punny. Obviously, this is a kid’s tale meaning Cam and Eric expose themselves to an absurd amount of risks despite the fact that the police is already investigating the crime anyway. And the k ...more

I really enjoyed reading this book. I chose it because I have never read it before and I found it in the library at my house. This book is a good beginner book for those children ready for chapter books. The book introduces new language and concepts. I enjoyed the mystery of the book, but the only drawback is if a child reads this book, I would not want them to take it seriously. If they did see a crime like Jennifer did, hopefully they know to report to an authority about it and not go chasing ...more

This story revolves around a young girl named Cam Jansen who has a fantastic photographic memory. One day while walking about Cam notices a stir going around the Jewelry store. She notices a man with a mustache leave along with a women carrying a baby stroller. The two disappeared before the police could show up. After this incident Cam makes it her duty to help solve the mystery of who stole the diamonds from the Jewelry store. I gave the book 3 stars because it could have been better and I fee ...more

Cam Jason and her friend Eric were at the mall, when the jeweller store was robed. The suspect was a man running, but he wasn’t the robber. Then Cam found out an important clue, a couple had a baby and only a rattle, but Eric's baby brother needed a bagful of things.
This book holds mystery, but in a good kid way. It shows photographic memory in action. Age range is 7 or 6 and up.
I like this book because I like mystery’s. My favourite part is when Cam hid from the bad guys. There is nothing I

My youngest daughter is 6 years old an in 1st grade, but her reading level is more on the line of a 4th grader, which makes finding books difficult. I need to find things interesting and difficult enough to engage her, but yet she is still a 1st grader and as such not mature enough for some books.

Last night, she and I sat down to read this book. Now, having been a Literacy Assistant (basically a teachers aide that taught reading) in our local school for the past two years, I knew that Cam Jansen

Cam Janson and her friend Eric Shelton were watching Eric's baby brother, Howie, at the mall while his parents went shopping. Near the bench they were sitting, the jewelry store's alarm went off and the people around panicked as a man wearing a green tie ran out of the store in a hurry. This made Cam very confused because there were plenty of exits around that he could have went for. Cam, who was nicknamed that after "camera" due to her photographic memory, noticed the other people who were a pa ...more

The original Cam Jansen series follows the exploits of 10-year-old 5th grader Jennifer "the Camera" (aka "Cam") Jansen and her best friend, classmate, and neighbor Eric Shelton. Cam got her nickname because of her photographic memory. All she has to do is say "Click," and Cam can remember everything she's seen, which comes in pretty handy when trying to solve mysteries.

David Adler has written several beginning chapter book series, but Cam Jansen is one of the earliest and most successful. He's b

When the streets get too hot, and crime is at its worst, count on Cam Jansen! She's a twelve-year-young junior detective with a photographic memory like a steel trap, and a sense of right and wrong which has trumped and stumped most older male private eyes! Her first adventure has Cam the Camera hanging with associate (read: BFF) Eric Sutton and Eric's baby brother. Then a lowlife happens to run from a jewelry he just robbed! Then two others are seen as carrying a baby of their own, ...more

Ages 8 & Up • Cam and Eric are sitting in the mall when an alarm goes off. Cam jumps onto a bench to get a better view and sees a man race out of the jewelry store. Cam knows that she has to act fast, especially after the police arrest the wrong person.

It's up to Cam and Eric to catch the real thief.

I always thought that the main character's name was Cameron, and she went by Cam as both a reference to her abilities and as a regular nickname. That, apparently, was not the case. Oops.

I first read this book as a kid. My best friend's name was Cameron, and so I started calling her Cam after reading this book. It annoyed her to no end. It was awesome. :)

Cam Jansen has photographic memory and a knack for solving mysteries. In this book, Cam witnesses some commotion in the mall. She and her friend, Eric, help the police find out who stole the diamonds from the Jewelry Store.

Mystery. Great in-between for Nancy Drew. Intermediate First-Chapter (longer sentences and more content on pages).

The both look around to see what is happening and see police officers arresting a man who is the so called jewelry thief. Cam and Eric decide that is up to them to catch the real thief, they then go on an adventure and attempt to get the thieves arrested. The author does an excellent job in helping the readers ...more

I always loved Cam Jansen books as a child. These books are great because they are easy to follow and the mysteries are serious but child-appropriate. The story is full of twists and turns, however there are enough hints to the solution that a child can have the success of solving the mystery themselves. In this story, Cam, a young girl with a photographic memory and a penchant for solving mysteries, solves the mystery of a jewelry store robbery. The main characters, Cam and her best friend, Eri ...more

This was a really good book with a mystery that was more real than a typical kids book. Most kids won't be able to have a true photographic memory, but it might encourage them to want to try and memorize more. I thought this book also had appropriate illustrations for the story.

"Fifth-grade sleuth Cam Jansen uses her photographic memory to catch a jewel thief." (From Amazon)

A great mystery/detective series - a great novel for young children (easy to read). For those who like Harriet the Spy and Encyclopedia Brown.

Cam Jansen series withstands the test of time though the fact that she and her best friend Eric (also in fifth grade) are watching his 1 year old baby sister in a shopping mall gives away that Stolen Diamonds was published in another era :)

I thought this book was really engaging for young readers. David Adler does a good job at reeling the reader in to get you hooked on this book. The basic plot line is that a girl Cam, (short for camera, due to her photographic memory) and her friend Eric witness a robbery and go to catch a mall thief that stole from a jewelry store. The setting and some things in the book are very realistic, which I prefer to read in childrens books. As the story progresses, Cam begins to go after the thieves on ...more
