Dead Simple: Peter James (Pan 70th Anniversary)

It was meant to be a harmless stag-night prank. A few hours later Michael Harrison has disappeared and his friends are dead. With only three days to the wedding, Detective Superintendent Roy Grace—a man haunted by the shadow of his own missing wife—is contacted by Michael's beautiful, distraught fiancée, Ashley Harper. Grace discovers that the one man who ought to know Michael Harrison's whereabouts is saying nothing. But then he has a lot more to gain than anyone realizes, for one man's disaster is another man's fortune.
