A US style private detective tale but coming from Britain, and it just about works.
Slim Callaghan (Michael Rennie) is called to the country home of Colonel Stenhurst (Roy Russell) but he is murdered just before he can tell Slim why he wants him. There are a number of suspects including the Colonel's three daughters (including Moira Lester). The case involves inheritances, secret marriages and blackmail...
This is a decent enough crime drama though tries a little too hard to copy US hard boiled detective stories which sometimes fails to come across properly in a British setting. The story is complicated with plenty of sub-plots though the film can be a little static at times. The final fight scene is well worth sticking around, Slim knowing a bit of judo!
