When four murders take place in a secluded English community, Scottish barrister Rex Graves is called on to lend his investigatory expertise. The only link between the victims is that their homes were up for sale. But when the local authorities arrest a shady house agent, letters written in blood on the bodies tip Rex off to a different kind of killer. Digging into the past, Rex discovers that the victims were not who they appeared to be. For the first time, he's not up against a lone operator. With his fiancee away on a cruise, Rex must race to solve the murder before she catches him indulging his forbidden crime-solving hobby . . . or before he becomes the latest victim.
