Three housemates.

One dead, one missing and one accused of murder.

Dubbed the Housemate Homicide, it's a mystery that has baffled Australians for almost a decade.

Melbourne-based journalist Olive Groves worked on the story as a junior reporter and became obsessed by the case. Now, nine years later, the missing housemate turns up dead on a remote property. Oli is once again assigned to the story, this time reluctantly paired with precocious millennial podcaster Cooper Ng.

As Oli and Cooper unearth new facts about the three housemates, a dark web of secrets is uncovered. The revelations catapult Oli back to the death of the first housemate, forcing her to confront past traumas and insecurities that have risen to the surface again.

What really happened between the three housemates that night? Will Oli's relentless search for the murderer put her new family in danger? And could her suspicion that the truth lies closer to home threaten her happiness and even her sanity?

A riveting, provocative thriller from the bestselling author of The Dark Lake, Into the Night and Where the Dead Go.
