Peter May is a prolific and superlative thriller writer. I've only read the first of The Lewis Trilogy, The Blackhouse, which is superbly evocative of the Isle of Lewis in Scotland's isolated Outer Hebrides. He returns to Lewis with The Coffin Road, but this book is not connected to the trilogy, and has different characters. It's very good! It opens with a man bewildered on a beach, with no memory of who he is. Then we have a detective learning that a body has been found on the remote Flannan Islands off the coast of Lewis, and a teenage girls in Edinburgh trying to discover what led her scientist father to kill himself 2 years previously. These three stories come together in an unexpected way. May manages the increasing tension of these three stories extremely well - the reader knows that they will coincide, but not how or when, and when they do, it's not necessarily how the reader would expect. Even for those who have never been to the Hebrides, this is a very satisfying thriller.
