The Sea Lock

A Scottish Highlands Murder Mystery

A canal worker is found drowned at the bottom of the Corpach sea lock.

The chamber was drained. The safety systems were intact. Donald Carrick had worked this lock for thirty-one years and knew every mechanism by heart.

DCI Sarah Lynch arrives to find a death that doesn't fit. The safety interlock was overridden from inside the control building. The sluices were opened deliberately. Someone called in Donald's routine check-in from his own phone while he was in the flooding chamber.

Someone who knew everything about how this lock worked.

As Sarah traces the careful chain of knowledge that led to Donald's death, she uncovers a secret buried for twenty-three years — a boy who drowned in the same water, a cover-up that destroyed nothing visibly and everything quietly, and a woman who had been waiting, with absolute patience, for the truth to finally arrive at her door.

The Sea Lock is the sixteenth book in the Detective Sarah Lynch series.
