The House On The Sound (Tide House Mysteries, #5)

At the bottom of the world, distance is not the same as safety. On a deep, cold sound in the far south of New Zealand, a grey man has kept his mother's record for thirty-one years — a record of the sister who went to a beloved school and never came home.

When it reaches the people who come now, DI Maya Anders travels to the end of the map, and Honor Whitling makes one last journey to stand at the edge of a case she can no longer run. The sound keeps its dead a long time in the cold. This year, it gives them back. The fifth Tide House Mystery.
