Robert Blair, a local solicitor, is called on to defend two women, Marion Sharpe and her mother, who are accused of kidnapping and beating a fifteen-year-old war orphan named Betty Kane. Set in Milford, the novel opens with the Sharpes about to be interviewed by local police and Scotland Yard, represented by Inspector Alan Grant (who is the protagonist of five other Tey novels). Marion calls Blair and, although his firm does not do criminal cases, he agrees to come out to their home, "The Franchise", to look out for their interests during the questioning.
