'Enter Inspector Duval' (1961) – Max Varnel.

This deceptively delightful, vastly neglected thriller stars everyone's favourite Teutonic villain Anton Diffring, the frightfully urbane, mellifluously-voiced Thespian now takes on the alternate Gallic mantle of indomitable Inspector Duval of the Sûreté, a most capable cop, his singular obsession to capture elusive cat burglar 'Mr. March' brings the meticulous sleuth to the UK, where a grisly crime scene bearing the signature hallmarks of a recent murder, strongly suggest that the wily, and wholly ruthless 'Mr. March' is actively perpetrating his cool, exacting mode of ruthless, well-planned larceny. Max Varnel's dynamic, conspicuously thrilling pulp-noir 'Enter Inspector Duval' is a sheer delight from start to finish, a neatly conceived vintage murder mystery, gloriously garlanded with another exceptionally refined performance from the effortlessly debonair Diffring, which culminates zestfully in a suitably exhilarating, playfully twisted, break-neck paced climax!
