Murder by the Clock - Rufus King

Lieutenant Valcour must solve the murder of a man who was murdered twice! At 8:34 P.M. the body of Mr. Endicott is first discovered. By midnight the corpse had been revived with a shot of adrenalin. By one o'clock A.M. he had been murdered again. There are many suspects and more than enough false trails. Follow along the timeline as Lt. Valcour uses his experience and intuitions in an attempt to determine who might be responsible. In 1931 a movie starring William "Hopalong Cassidy" Boyd as Lt. Valcour was released to an anxious public. - Summary by Roger Melin
