Trampoline experts Trudy Manders and her father, a sergeant instructor in the Army, have joined a circus touring Germany, as a cover in their search for Professor Goldsmith, a missing British scientist. Their only contact with the Secret Service is a mysterious character known as The Mouse. From information received in messages from The Mouse and in other ways, the Manders suspect that Frankel, the circus lion-tamer, is connected with the Professor’s disappearance. Unknown to Trudy, Frankel has decided that she is too inquisitive, and he is out to get her!
