Bill Shane is The Lad, an opportunistic petty criminal mistaken for a private detective. When Shane arrives at a remote country estate, he's offered much money not to delve into the private affairs of the Fandon family. Shane is all for taking the money and duping the family, but on being reunited with ex-girlfriend Pauline, now the Fandon's maid, he decides to turn over a new leaf.
The Radio Times wrote, "Gordon Harker was such a favourite of crime writer Edgar Wallace that he frequently had material especially tailored for him. It's hardly surprising, therefore, that the actor is totally at home in this serviceable adaptation of one of Wallace's most popular thrillers...Director Henry Edwards wisely keeps the action brisk and on the light side, as the mystery is hardly baffling and the performances are painfully stiff."[3]
