Set-up for the Chet Gecko Mystery series has Chet taking on a case at school where the little brother of a girl he likes is missing. The doll does not give Chet all the info she has and he has to do a little detective work. He gets a sidekick he didn't want with Natalie but it is a good thing she's there. She's got the brains.
I enjoyed this book. The world building is good. It reminded me of a 1940's Film Noir movie. I liked Chet's thought process. He needs Natalie but eventually figures it out. I loved the humor and cannot wait to read the rest of the series.
