Early evidence leads Bert and June to a cave which leads to an isolated beach, and contains gear belonging to the gang. They are unaware, however, that in a minisub off this beach's shoreline hides Zorn, the counterfeiter who is printing the phoney bills. Ultimately, however, the evidence points to an unknown, higher authority directing the operations of these men, and apparently indeed someone connected with the circus. Among the most suspicious-acting of the circus staff are Burton the clown, and any of three "rubes", at least one of whom seems to be lurking by when something threatens the life of Bert or June.
