A tense psychological crime thriller by Lin Anderson and part of the acclaimed Rhona MacLeod series.

The story centers on a remote estate in the Scottish Highlands known locally as the "Party House," a place with a dark reputation linked to wild gatherings, secrets, and tragedy. When a young woman disappears after attending a party there, concerns quickly escalate into a major investigation.

Forensic scientist Rhona MacLeod is drawn into the case as evidence begins to reveal a disturbing pattern of deception, abuse, and long-buried secrets. As the investigation progresses, the isolated setting and the silence of those involved make uncovering the truth increasingly difficult.

Combining forensic science, psychological suspense, and atmospheric Scottish settings, the novel gradually builds tension while exploring themes of exploitation, trauma, privilege, and justice.
