Previously filmed in 1928, the old Edgar Wallace novel
The Terror was dusted off for another cinematic go-round ten years later. A spectacular crime spree, instigated by a mysterious miscreant known only as "The Terror", has galvanized Scotland Yard into action. The trail of clues leads to a ramshackle old castle, owned by retired Army doctor Col. Redmayne (
Arthur Wontner). The detective on the scene is one Mr. Goodman (
Wilfred Lawson), who has devoted 10 years of his life to bringing The Terror to justice. Among the suspects are such low-lifes as Ferdie Fane (
Bernard Lee) and Soapy Marks (
Alastair Sim), but the identity of The Terror comes as quite a surprise to all concerned (except for those dyed-in-the-wool mystery fans who pegged the villain's identity as the credits unreeled!) ~ Hal Erickson, All Movie Guide
