Troubled Waters — Gillian Galbraith

A young disabled girl is lost on a winter's night in Leith, unable to help herself or find her way home. Someone is combing the streets, frantically searching for her. Within hours of her disappearance, a body is washed up on Beamer Rock, a tiny island in the Forth being used as part of the foundations for the new Queensferry bridge. No sooner has Detective Inspector Alice Rice discovered the identity of that body than another one is washed up on the edge of the estuary, in Belhaven Bay. What is the connection between the two bodies? Is another victim in the killer's sight and if so, can Alice solve the puzzle before another life is taken? In this novel, the sixth in the Alice Rice Mystery series, appearances belie reality, and truths and falsehoods become indistinguishable.
