The House Below the Tide. Tide House Mysteries, #2

The sea gives up its secrets eventually. Sometimes it takes years. When a man is found dead inside an abandoned salt boathouse on the North Yorkshire coast, Detective Inspector Honor Whitling is pulled into a case that feels disturbingly familiar. The victim had enemies. The town has secrets. And everyone seems to know more than they will say. As Honor digs, long-buried tensions rise - hidden relationships, old betrayals, and something darker tied to Tide House itself.
Because someone has worked very hard to keep the past buried, and they will do whatever it takes to keep it that way. For readers of Ann Cleeves, Elly Griffiths, and Deborah Crombie.
