Operation Murder is a 1957 British 'B'[1] crime film directed by Ernest Morris and starring Tom Conway, Patrick Holt and Sandra Dorne.

A scheme by two doctors to establish an alibi for a killing by switching roles in the operating theatre is foiled by the insight of a detective and the chance action of a small boy.

The Monthly Film Bulletin wrote: "The familiar crime-and-detection formulas are applied in a manner conventional to the point of dullness; and the acting does little to brighten things up.

The cast contains popular names, but the leading players fail to achieve the impossible and seal the many loopholes in its sketchy script.

John Stone does a neat job as Inspector Price, but Tom Conway and Patrick Holt are forced to behave as if they want their heads examined as Doctors Wayne and Bowen and Sandra Dorne is completely wasted as Wayne's extravagant wife.
