Celebrate more than 25 years of Horrible Harry with the 30th book in

Catastrophe strikes Room 3B when the diamond on Miss Mackle's engagement
ring disappears. Fortunately, Harry is on the case! The third-grade
talent show is coming up, and he wants to show off his skills as South
School's greatest detective. Doug, on the other hand, has no idea what
to do for his act. The best friends need to find both Doug's talent
and the teacher's diamond, or else the talent show will be a horrible
disaster for everyone!
