Harry is in Budapest with Anna Sandor, a lawyer committed to women's rights who wants him to perform a second autopsy on Sofi, a pregnant Romanian prostitute drowned in the Danube. Anna disbelieves the official version that Sofi killed herself but the body is quickly cremated and Anna is murdered. Harry is pursued by the gangsters who killed her, hiding out with street dweller Janos, who tells him not to trust the police. Leo answers Harry's distress call and flies out but Anna's doctor father believes Harry murdered her and detective Orban tells Leo Anna was pregnant by Harry. Harry breaks into Anna's office, finding links to a brothel run by the same tattooed men who pursued him. He and Janos flee but the men shoot them. Leo suspects police duplicity in the gang's ability to locate Harry so quickly.

Nikki flies to Budapest and is called to a secret meeting with Leo to avoid Orban. Harry appears, having faked his death to pursue his enquiries. From another prostitute Marina he learns that the gang use the girls to produce babies for influential people who, for various reasons, cannot have children of their own. If the girls are HIV positive like Sofi, they are killed, a fact that Anna had uncovered. Harry approaches Anna's father who says he knew what was happening but wanted to shield Anna from it, before dropping another bombshell. With the British ambassador and other dignitaries involved in the plot, the pathologists have to trust Orban if they are to bring an end to the racket.
