In a contemporary review,
The Monthly Film Bulletin wrote: "A holding thriller, with a fairly plausible London background, racy direction, occasional laconic humour, and skilful though! familiar performances from John Gregson – doggedly and moodily honest – and Herbert Lom, suavely villainous."
Variety described it as "a conventional but brisk gangster yarn," concluding that "Herbert Lom plays the brains of the crooked organization with urbane villainy and equally reliable John Gregson makes a solid, confident job of the dedicated cop. Alfred Marks is cast offbeat as Lom’s gangster lieutenant. Marks gives a rich, oily, sinister and yet often amusing portrayal of an ambitious thug who is prepared to turn killer to get his own way. Comparative newcomer, rugged Sean Connery makes a distinct impression as an Irish crook, with an eye for the ladies. Connery combines toughness, charm and Irish blarney."
The Radio Times Guide to Films gave the film 2/5 stars, writing: "Limping along years after Hollywood's postwar exterior location thrillers such as
The Naked City, this British attempt at the genre just about manages to hold the interest. The story is about London gangsters falling out over a protection racket, and features a young Sean Connery and a pre-Pink Panther Herbert Lom at his most seedily sinister." According to a review on the
AllMovie website: "The film itself is only of moderate interest, a gangster thriller that's engaging but not special; but the cast makes it worth watching." ==References==
