The Monthly Film Bulletin wrote: "The first of a series of one-hour second features adapted from Edgar Wallace, brought up to date but unable to avoid the slightly old-fashioned look one associates with Wallace's theatricality and liking for red herrings, Clue of the Twisted Candle nevertheless augurs well for the stories to come. After a slow start, curiosity is aroused and resourcefully maintained, with solid backgrounds, crisp playing and economical treatment lending the film an expert air."^[4]
