Twenty years ago, Charlie Deravin’s mother went missing near the family beach shack – believed murdered. Her body never found. His father has lived under a cloud of suspicion ever since. Now Charlie’s back living in the shack in Menlo Beach, on disciplinary leave from his job with the police sex-crimes unit, and permanent leave from his marriage. After two decades worrying away at the mystery of his mother’s disappearance, he’s run out of leads. Then the skeletal remains of two people are found in the excavation of a new building site – and the past comes crashing in on Charlie.
