This is a run-of-the-mill police drama noteworthy for being directed by John Ford. Lots of familiar British character players give it some interest but it compares poorly with The Long Arm, another police picture also starring Jack Hawkins. I don't usually spot mistakes in films but I did notice two in this one. When policeman Andrew Ray follows killer Laurence Naismith down the street he picks up the newspaper Naismith has dropped and we see the headline. When we see it again it has a different headline. When Hawkins' wife Anna Lee takes a hot casserole from the oven she uses an oven cloth but two minutes later daughter Anna Massey takes the lid off with her bare hand.
