Entry Island is in the archipelago in the Gulf of St. Lawrence off the coast of Quebec.  When a murder rocks this small island, homicide detective Sime Mackenzie becomes part of an investigative team sent from Montreal to oversee the crime.  The victim is the wealthiest inhabitant among the island's population of just more than 100.  The dead man's wife becomes a prime suspect, although she spins a tale for the police about a masked intruder with a knife who was trying to attack her.  While the evidence points to a crime of passion implicating the wife, the investigation appears to be little more than a formality; but when Sime meets the victim's wife, Kirsty, he is struck with an unshakable feeling that he knows her...although they have never met.  Mackenzie, who suffers from insomnia, dreams of 19th century Scottish farmers and their struggles with a powerful laird which affected his ancestors and possibly Kirsty's too, providing a forceful element to the current-day story line.  How can Sime's ring and Kirsty's pendant, each set with a semiprecious stone which bears an engraving of the same family crest, have a link to this brutal murder?  After reading the Lewis Trilogy, Peter May has become a must-read author for me.  Don't miss this new stand-alone suspense thriller which I highly recommend.  (Quercus, $26.99).
