The lead homicide investigator in a rural town, Detective Sergeant Gemma Woodstock is deeply unnerved when a high school classmate is found strangled, her body floating in a lake. And not just any classmate, but Rosalind Ryan, whose beauty and inscrutability exerted a magnetic pull on Smithson High School, first during Rosalind's student years and then again when she returned to teach drama. As much as Rosalind's life was a mystery to Gemma when they were students together, her death presents even more of a puzzle. What made Rosalind quit her teaching job in Sydney and return to her hometown? Why did she live in a small, run-down apartment when her father was one of the town's richest men? And despite her many admirers, did anyone in the town truly know her? Rosalind's enigmas frustrate and obsess Gemma, who has her own dangerous secrets--an affair with her colleague and past tragedies that may not stay in the past.
