The Secret of the Old Diary

Casey is back on the investigation! This time, things are downright strange… Pets are disappearing everywhere, and a pet chimpanzee has taken in a kitten that seems to appear out of nowhere. But that’s not where the problems end. The café where Casey opened her office is in danger of closing. And Freddy the ferret finds an old diary full of puzzles and a mysterious map. Could it be a treasure map—and maybe the café, and with it the agency, can still be saved!
