Synopsis: In an unusual move for a mere program picture, RKO Radio filmed A Saint in London on location in England, using a largely British cast and crew. George Sanders makes his second appearance as suave soldier of fortune Simon Templer, aka The Saint. This time, Templar gets mixed up with a gang of counterfeiters who've murdered and robbed a European count of 1,000,000 pounds. He is aided reluctantly by Scotland Yard inspector Teal (Gordon McLeod), who's convinced that Templar himself pulled off the heist, and less reluctantly by light-fingered Dugan (David Burns) and dizzy socialite Penny Parker (Sally Gray). The Saint in London was directed by John Paddy Carstairs, who later worked on some of the episodes of the Saint TV series.
