When a popular singer goes from retired to dead the day before New Year's Eve, Ellery Queen is certain it's murder. Luckily, just before she died, the victim managed to scribble out a single mysterious word: F A C E. Unfortunately, no one knows what it means.

With the help of a new acquaintance, Inspector Harry Burke from Scotland, Queen uncovers even more baffling clues written in invisible ink. Enter the beautiful, discarded conquests of the dead singer's playboy husband, who prove a dangerous distraction for both Queen and Burke. Will erotic temptation derail the investigation? If it does, hearts will be broken, and what's worse -- someone will get away with murder.
