William Hartnelll always made interesting parts in interesting films, so that you could rely on his name to warrant a reward. This is a typical example, although you have to wait for his appearance, in a role out of the ordinary for him, for he is the criminal inspector. The stars are instead the crooks, George Mikell as a rather interesting and fascinating victim of injustice coming for his exoneration, and Eddie Byrne as the real villain, a gangster and leader of mobs who has made a fortune on his rackets, whom George Mikell with a German accent pays a visit to get back what has been stolen from him. Eddie Byrne refuses to cooperate, so there is a conflict, and Mikell robs him of £6000, which Eddie Byrne naturally raises hell by mishandling every person in connection with Mikell, trying to learn where the renegade is. Naturally there is a final settlement between the two, which naturally ends bad for both of them. We never learn what happened to the survivors.
It's an efficient thriller, well written with a top cast all the way, and every supporting part earns some high credits. The music like the drama is hard-boiled and perhaps a little too invasive, and the finale could have been made more efficient. However, as it is, the thriller is efficient enough with many interesting currents, every supporting part being of major importance.
