The theme is blackmail in 1940s Hollywood, where appearances are everything and no one cares what you're doing as long as it doesn't become public knowledge.
The heroine is a strong-minded, intelligent woman who suddenly finds herself the victim of ruthless blackmailers. What they don't count on is that this is a woman who refuses to be a victim and will fight back just as ruthlessly.
York has written a wonderfully literate mystery, rich in setting and characterization. The characters are vivid and very believable, and the atmosphere created makes you feel like you've gone back in time and space to Hollywood in the late 1940s.
