For the "Nameless Detective," investigations involving matters of the heart are to be avoided. But when an old poker buddy asks him to help frazzled and distraught Kay Runyon, whose husband, Victor, is having a clandestine affair with a mystery woman named Nedra, Nameless relents. After all, it seems like a simple matter: Find out just who Nedra is so Kay can confront her in a last-ditch effort to save her marriage.

But Nameless soon discovers that there is much more at stake than a simple affair. Nedra is a modern-day Circe who attracts men who become obsessed with her, in some cases dangerously so. Victor Runyon is the latest in a long line; others whose paths Nameless crosses include a violent ex-convict, Nedra's jealous ex-husband, and a powerful San Francisco politician.

Victor's obsession with Nedra takes a bizarre twist when she suddenly vanishes without a trace. Did she disappear willingly or was she the victim of one of her lovers' private demons? Nameless must find out before it's too late to save Victor and Kay from tragic ends. And he must do so while trying to cope with a very personal and private demon of his own.

Demons is a powerful tale of psychological suspense that builds inexorably to a chilling and shocking climax.
