The story unfolds in two stories. The first begins in 1866, with a mystery: a politician, Alastair Lauderback, arrives at a cottage to find a woman, unconscious with opium; a Māori man, also unconscious; and a corpse. Lauderback brings the woman to town, where she is arrested for public intoxication and held at the jail. The jailer identifies her as the prostitute Anna Wetherell. The corpse is brought back from the cottage and identified as Crosbie Wells. The town jailer, George Shepard, mounts a murder investigation with Anna as his prime suspect. Anna discovers that a fortune in gold has been inexplicably stitched into the lining of the dress she is wearing. She uses part of it to pay her bail. The second story takes us back nine months earlier to 1865, beginning on the day of Anna's first arrival in New Zealand. She is fresh-faced and full of promise. After a romantic first encounter with a fellow passenger, Emery Staines, she arranges to meet him again. But the scheming fortune-teller Lydia Wells arranges for Anna's purse to be stolen. Realizing that Anna is illiterate, Lydia lies about Emery's whereabouts. Anna is taken under Lydia's wing, and Emery under the wing of Lydia's lover, the former convict Francis Carver. Emery and Carver are interrupted by a Chinese man who shouts at Carver in Cantonese and then tries to kill Carver, who only narrowly escapes. Lydia's husband, Crosbie Wells, returns home from the goldfield having made a strike.
