This is a neat, entertaining and witty British movie from the 1950's which is very much enhanced by an excellent lead performance by Derrick De Marney as Slim Callaghan. Based on a Peter Cheyney novel, and featuring his main character of Callaghan, the film moves along at a brisk pace, and the plot, which is quite involved, never sags and retains the viewers interest all the way. This is helped in no small way by a sharp and vibrant script. Although other actors have portrayed Slim Callaghan, there is little doubt that De Marney is by far the best. His laconic and downbeat style fits the character perfectly, and it is a pity that it was never put to further good purpose. In many ways, he provides a perfect comparison to similar American-style gumshoes in movies from the 40's and 50's, in particular. The scene in the nightclub, when he is tempted by singer Adrienne Corri, is a joy of deadpan expression and he certainly carries this film along in a thoroughly expert way. You are left with the distinct impression that this is how the author imagined his main character to be. All in all, a film well worth catching and one that should gain a wider audience.
