Downfall is yet another hour-long entry in the seemingly endless series of British-filmed Edgar Wallace mysteries. Maurice Denham plays a brilliant attorney who arranges an acquittal for murderer T.P. McKenna. It's all part of Denham's master scheme to divest himself of his wife (Nadja Regan). Denham hires McKenna as his chauffeur, then blackmails the poor bloke into murdering the wife. Downfall was the 22nd entry in Merton Park's Edgar Wallace series. ~ Hal Erickson, Rovi
