Time Thief (Solve Your Own Mystery 2) by Gareth P. Jones

What worked:

The series includes a good deal of humor and strange events, which should appeal to young readers. Detective Klaus drives a car that used to be a dog. It wags its tailpipe when it’s happy or excited and makes soft, satisfied sounds when you scratch its car seats. Two talking gargoyle statues watch a museum’s back entrance, where a medusa-like character is the curator. The main police inspector is a minotaur, and the lead detective is an elf walking on stilts. A banshee news reporter details the facts of her stories, or she makes them up to make the stories more appealing to her readers.

The premise of the series is that the reader is Klaus’s assistant, and they make decisions on which clues to follow. Young readers will enjoy skipping pages to arrive at the next step in the story they have chosen. The different sections aren’t very long, which is appealing to young or reluctant readers. Like real detectives, readers identify the cast of suspects, examine their motives, and decide if they had opportunities to commit the crime. There’s always evidence pointing to different suspects, but readers eventually discover clues that narrow their focus. The book says there are three possible conclusions, depending on which clues are followed. The last page of the story lets readers move to alternate endings by directing them to different parts of the book. 

What didn’t work as well:

There isn’t much time spent developing characters or describing the events in detail. However, that’s the trade-off for skipping around to different parts of the plot. Readers may be curious about Klaus’s time with the UPF when he was the lead detective on the police force. It’s been mentioned in both books, but readers are left to wonder about anything specific. 

The final verdict:

Books that allow readers to choose how the stories unfold are always entertaining, and this one adds mystery and humor. Overall, I recommend this book to all middle-grade readers.
