13 East Street

Patrick Holt robs a jewelry store. He is quickly caught and sentenced to prison. He escapes with his cellmate and they make their way to London's docklands, where they join Robert Ayre's gang. Henchman Michael Brennan suspects him, but Ayre's girlfriend, Sandra Dorne, decides she likes Holt. It turns out Mack is right; Holt is an undercover copper, out to infiltrate and break up the gang.

It's a taut little second feature as Holt tries to do his job while Brennan slowly finds grounds for his suspicions, with some nice interludes with Sonia Holm (Holt's real wife at the time) and Dora Bryan as a gossipy neighbor. It's got some beautiful photography, shot by producer-cinematographer Monty Berman. He and co-producer Robert Baker would later strike gold with the TV series THE SAINT.
