I Love a Mystery was a campy TV revival of Phillips Lord's old radio series. The three adventure-loving heroes are Jack, Doc and Reggie (Les Crane, David Hartman and Hagan Beggs), insurance investigators hired to tackle a mystery at a remote island mansion. Ida Lupino plays a domineering matriarch whose billionaire husband is missing, and who seems to know more than she's letting on. The mystery's ingredients include the eerie nocturnal sound of a crying baby and a series of related murders and kidnappings. The heroes are occasionally distracted from their work by Lupino's nubile daughters Faith, Hope and Charity (Karen Jensen, Deanna Lund and Melodie Johnson). The script for I Love a Mystery was based on Philips Lord's classic radio serial "The Thing That Cries in the Night," but there's nothing classic or even remotely entertaining about the derisive, patronizing treatment of the source material herein. This made-for-TV "busted pilot" gathered dust for seven years before its 1973 premiere, and not without just cause. A further note: Though Don Knotts is advertised as one of the "stars," he shows up to sputter one miserable line at the end of the film!
