A man dead in his seat. A hat gone missing. And a theater full of secrets.

Inside the prestigious Roman Theater in the heart of 1930s Manhattan, a packed house is stunned when a well-dressed man is found murdered during a performance—the only apparent clue a mysteriously missing hat. Enter Ellery Queen, the brilliant amateur detective with a razor-sharp mind and a flair for the unconventional. Together with his father, Inspector Richard Queen of the NYPD, Ellery unravels a tangled web of deception, blackmail, and high-society scandal hidden beneath the city's glittering entertainment scene. But as the investigation deepens, the mystery only grows more intricate. Why was the victim sitting alone? What was hidden inside the missing hat? And what secret was so deadly it demanded murder? The narration reveals every clue for readers to follow while concealing Ellery's final deductions until the climactic solution. Near the end of the novel, the authors issue their famous "Challenge to the Reader," announcing that all the necessary clues have been presented and inviting readers to solve the crime before Ellery reveals the answer. It's an irresistible opportunity to match wits with one of literature's greatest gentleman detectives.
