"The vampire bat has struck again!" Chet quavered. This looks like another clue for The Hardy Boys by Franklin W. Dixon. One of the exciting parts is when Biff (The Hardy boys friend), kicks and sends a knife flying out of a counterfeiters hands. I like that part because he saves everybody: Joe, Frank, Chet, and himself! If you like mysteries, you should read The Hardy Boys series, especially book 50! Also, I have heard that The Nancy Drew characters SOMETIMES meet up with the Hardy Boys.
