Blackout is a 1950 British second feature ('B')[2] crime drama film directed by Robert S. Baker and starring Maxwell Reed and Dinah Sheridan.

He returns to the house to find Patricia Dale living there with her father and from a photo on the piano he realises that the ring belongs to her brother, Norman, who is presumed dead after a plane crash a year before.

Chalky gives them a couple of leads, and when Pelley follows up one at a travel agency he meets Guy Sinclair who works there and whose voice Pelly recognises as one of the three men who knocked him out.

It then transpires that her brother Norman is alive and is actually the gang's ringleader who faked his own death to evade arrest; the body Pelley stumbled over in the house was that of a customs investigator.
