Philo Vance #93, "Golden Key Murder Case," Philo Vance returns from a three-day trip to find his secretary Ellen waiting with an unusual delivery: a mysterious golden key that arrived in the mail with no accompanying letter or explanation. Their lighthearted banter about his absence quickly turns dark when Vance enters his private office and makes a chilling discovery—a dead man is sitting at his desk, clutching another golden key in his hand.
What begins as a peculiar puzzle transforms into a murder investigation as Vance must determine the identity of the victim and the significance of the matching golden keys. With District Attorney Markham having just called moments before the grim discovery, Vance finds himself pulled into a case that has literally arrived on his doorstep. The enigmatic keys suggest a carefully planned message, but who sent them and why remains a deadly mystery that only Philo Vance can unravel.
