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."
Variety wrote: "Compared to other Wallace films, this is tame stuff. Disregard the usual mild production values, pat camera setups and choppy editing. However, the usual bizarre characterizations are not present, Bernard Lee is engagingly enthusiastic as the persistent Yard man, and David Knight is occasionally effective in his dual role; but the balance of the cast is lacklustre, without sufficient motivation or eccentricities. Then too, there is little of the gruesome, fast paced action which usually inhabits Wallace pictures. Too much of the story occurs offscreen, especially the key murder sequences. Scripter Mackie and director Davis were just not inventive enough to make this programmer the satisfactory interlude it potentially might have been. Except for Lee's dynamic chomping away to track down the villain, the story lags along too predictably, with no real puzzle for mystery fans seeking a diverting whodunit."
Picture Show wrote: "really gripping entertainment ...a plot packed with red herrings, all kinds of twists, melodrama and romance. And it’s only an hour long. There just isn't time to be bored." ==References==
