Margaret Fielding was tried for the murder of her first husband ten years ago and, innocent, was acquitted for lack of evidence. Now someone is threatening to produce evidence that could convict her.
Classic crime from one of the greats of the Detection Club
Fortunately, Margaret meets Arthur Crook, the detective lawyer to whom the innocent turn, never in vain. When her blackmailer is found murdered, just after she is seen, distraught, leaving the premises, it is to Crook that she tells her tale. But someone knows Crook by reputation, and is anxious that he does not take on Margaret's case.
