The body of Herbert Endicott is discovered by his wife at 8:37 PM, dead in his walk-in closet. The circumstances seem suspicious but there is no evidence of foul play, so Lieutenant Valcour, New York's most astute investigator, orders an autopsy on site. The doctor discovers a faint heartbeat and, with an injection of adrenaline, Endicott is alive again. But just a few hours later, he has been shot dead--this time for good.
From this puzzling set-up, an atmospheric and tense mystery ensues, with Valcour's research turning up more questions than answers. Before twenty-four hours are up, the solution will be uncovered.
