Derrick De Marney plays Slim Callaghan as a poor mans version of Sam Spade or Phillip Marlowe rather unsuccessfully.The air of world wide cynicism may work for Bogart or Dick Powell but it doesn't work for him.This is one of those rather over plotted thrillers where the private eye is always one step ahead of the dimwitted police and the actual killer comes as little surprise when the identity is revealed in the denouement.In the meantime Adrienne Corri is given time to warble a ballad in a nightclub and show a lot of fiery temperament.There is the usual attempt at a funny sidekick,from an actor i do not remember>Michae Balfour who normally fills these roles has a small part as a bartender.Fairly undistinguished all round.

Derek de Marney is Peter Cheyney's tough British private eye Slim Callaghan who in this "pilot" for a proposed Callaghan movie series, requires him to solve the mystery behind the death of a much-hated rich man. Callagham, a fictional British private detective in the American "hard boiled" mode, was the central character in several popular Peter Cheyney novels, in a stage play by Gerald Verner, and in the 1948 movie programmer UNEASY TERMS (also available below), which starred Michael Rennie. Directed by Charles Saunders (JUNGLE STREET, THE GENTLE TRAP, KILL HER GENTLY, BEHIND THE HEADLINES, NAKED FURY, THE NARROWING CIRCLE, A TIME TO KILL, THE END OF THE LINE, DANGER BY MY SIDE).

Derrick de Marney plays private detective Slim Callaghan in this fast paced British mystery. Callaghan is a bright, fast talking fellow, but still his detective agency has fallen on hard times. So when a young socialite drops in at his office close to midnight and drops 500 pounds sterling on his desk he jumps at the case. The heiress wants Callaghan to protect her as she fears her wealthy stepfather may be murdered and that the guilty person will implicate her.Callaghan smells something fishy right away, but can't turn down the cash. When he learns that the stepfather has already been murdered he begins to suspect his client may be the killer. Still, he works hard and quickly to gather information. He probes all angles and doesn't miss a chance to fatten his own wallet at every opportunity.This is the second film based on the character created by Peter Cheyney. The first film is Uneasy Terms, with Michael Rennie playing Slim Callaghan.

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.
