No mystery is too great for super-sleuth Cam Jansen and her amazing photographic memory!

Mysteries follow super-sleuth Cam Jansen everywhere she goes...even to an amusement park. Cam, Eric, and Cam's aunt Katie and uncle George have just braved the amusement park's Haunted House when Aunt Katie realizes that her wallet is missing. Did she lose it or was it stolen? Cam is convinced that this is the start of a very spooky mystery!
