Following his stunning trilogy of suspense novels set on the Scottish Isle of Lewis, Peter May won the 2014 Deanston Scottish Crime Novel of the Year Award and France's Trophée 813 for Best Foreign Crime Novel of 2015 with this standalone novel set on a tiny island off the coast of Quebec. Entry Island is home to barely more than 100 inhabitants, the wealthiest of whom has been found murdered in his home, with his wife covered in his blood. Insomniac homicide detective Sime Mackenzie, part of an investigation team from Montreal, is electrified by the man's melancholy widow, and convinced he has met her before. His sleepless nights are punctuated by vivid hallucinations of her, and himself, in a distant past in Scotland.
