The Case of the Waltzing Mouse

Gustave von Maltzbenden's pet mouse Xenophon can waltz. This is not strange because Gustave is an animal trainer. What does seem strange to Brains Benton and Jimmy Carson is that Gustave, and Xenophon have disapeared, leaving behind a trailerful of hungry animals, a fortune in bills where only a skindiver could find it, and enough clues to send the members of the Benton and Carson International Detective Agency on the wildest boat ride of their young lives.
