Lew Bascom is an idea man, and he has quite an idea. To put his career on the fast track, Bascom plans to pen a film about Hollywood's longest-running theatrical feud--Blythe Stewart and her daughter Bonnie's rivalry with Jack Royale and his son Ty. The twist? Bascom wants the four actors to play themselves in the film. The film's producer insists on bringing Ellery Queen, a successful New York writer, out to Hollywood to help close the deal. Only problem is that Bascom - a notorious procrastinator - isn't interested in outside help. So beautiful gossip columnist Paula Paris offers Queen an in by explaining the specifics of the feud ranging back to when Blythe and Jack were in a hot and heavy romance, throughout their unexpected separation, and into their subsequent marriages to other people. Meanwhile, the deepening hatred of their adult children has become the latest tabloid fodder. But when Blythe Steward and Jack Royale turn up dead, Queen must go from screenwriter to mystery solver before more Hollywood superstars become Hollywood casualties.

Raised in Japan by American expatriates, Karen Leith now lives a reclusive life in New York, known chiefly for her highly regarded novels, of which the latest has won a major American literary award. When she is found on the floor behind her desk, surrounded by blood, it looks like foul play. But the only possible suspect is Leith's future daughter-in-law, Eva, who has recently become engaged. Eva swears by her innocence, even though she was the last to hear Leith alive and the first to find her dead. Eva was waiting outside Leith's office to share the happy news and maintains that no one entered through that door, while the room's other possible exit was locked. The only one who can help her clear her name is mystery writer Ellery Queen, an acquaintance of the victim through New York's literary circles. Queen intends to unravel the locked-room mystery, but with no murder weapon and too many incriminating fingerprints, this case just might be one even he can't solve.
