On a deserted Riverside Drive at three in the morning, a young man in evening dress glimpses a face full of hatred, and the encounter draws him and a quick-witted young woman named Jane into a hunt for enemy agents in New York. Strange cards, coded books, missing messages and eavesdropping neighbours lead them into the apartment next door.
