The Armchair Detective on AllMovie

Created by Ernest Dudley, The Armchair Detective was a BBC radio anthology, tied in with a series of popular detective novels. The film version of Armchair Detective features Dudley as "himself", both narrating the story and acting as sidelines observer. Sally Newton co-stars as a radio singer suspected of murdering her hateful boss. Her friend Hartley Power tries to expose the real killer before Scotland Yard inspector Derek Elphinstone can pounce upon the poor girl. If Elphinstone seems to have all the best lines, it may be because he wrote the script.
