This is one of my favourites from Kate Ellis's Wesley Peterson series. It combines the mystery of a big old house, a skeleton in an ice house, a village collapsing into the sea - and starts with the discovery of a corpse in a hotel room, whose name doesn't match his identity!
In this story it was the historical element which grabbed me - the hundred-year-old diary of a maid who worked at the local 'big house'. I was also fascinated by story of the village collapsing into the sea - and a note at the back of the book explains that this is based on an actual event.
Particularly nail-biting was a member of Wesley's family being caught up in the present day investigation and one of the main characters becoming trapped in what remained of that lost village. How do all these seemingly unconnected events tie up? In a brilliantly clever way! One of Kate Ellis's best, and thoroughly recommended!
