John Currie, a chemist, is murdered, with evidence that he was an abortionist who treated his clients with dangerous lead compounds. His apprentice points the police to a deserted surgery and a strong box, containing evidence that the doctor who owned the surgery was experimenting in sterilization. Dr Frayn persuades Susan to employ Dr Rolle, who will conduct medically supervised terminations to prevent girls visiting back street abortionists but it is too late for Mary Tait, mutilated by Currie and the cause of a fight between her boyfriend Edwin Havelock and her adopted father George Tait. Reid discovers that both George and Rolle have very dark secrets, which lead to the solving of Currie's murderer. Having outwitted a fraudulent property developer Susan is still pursued by Fred for more news of the train robbery loot and then confronted by her father Theodore Swift, who has fled from America.
