After the early tense scene where the blind Captain Dan Adams finds the dead body in the wrong house and gets knocked out the film becomes a routine mystery story with no surprises. It was obvious that Johnny Brent was still alive and that 'Chalky' White was part of the diamond smuggling gang. The only reason to watch the film is the abundance of good and familiar acting talent; Delphi Lawrence, Gordon Jackson, John Le Mesurier, George Pastell, Arthur Lowe, Andrew Faulds, John Crawford and in a brief but effective appearance Michael Caine as the seemingly lost brother. It was a re-make of 'Blackout' from 1950, not better but not worse either.
