A lawyer becomes a government secret agent after an agent-friend of his is murdered, and discovers a nest of German spies operating out of a former client's hotel.

Carl Becker, a young attorney becomes a counter-espionage agent after an agent friend of his is murdered. He doesn't realize that the girl, Paula Fengler, with whom he is deeply in love, is a member of a clever group of German spies led by Dr. Woolford. He learns her true identity, arrests her, and traps the entire gang at the same time. The information he has allows a U.S. patrol boat to sink a German submarine that had been offshore waiting for instructions from the saboteurs.—Les Adams <[email protected]>
