The fake diamond in Dilys Holland's engagement ring implies that all is not well in her marriage, and the Holland family matriarch, Sybil, calls on Bea Abbot for help. Bea soon discovers that Dilys and her little girl live in fear of her abusive husband, a man called Benton with whom Bea has already clashed.

Benton wants Bea to rescue the ailing fortunes of his company, part of the Holland empire, and has no scruples about trying violence on her too when she turns him down. To make matters worse, Bea's Member of Parliament son has tied both his fortune and his marriage to Benton's future and is desperate for Bea to rescue him. Then Dilys tries to commit suicide . . . or does she?
