The Night People were an urban myth, weren't they?

A bunch of freaks and other deformed men and women who preferred their own company to that of the people who hated and reviled them. It was said they lived in the sewers beneath New York City, with all the snakes and alligators. People laughed at the idea that such a society could live, undetected, beneath the busiest metropolis in the world.

But Larry Kent knew different. The Night People existed, all right, and they were friends of his.

When multi-millionaire Gordon Pierson's daughter was kidnapped—apparently by the normally peaceful Night People—he hired Larry to find her and bring her home again.

He dare not fail ... because if he did, Pierson promised to mobilize the National Guard and clean out the sewers with guns and flamethrowers.

The fate of the Night People lay in Larry's hands.
