Murder on the Moor (A Rex Graves Mystery) [signed] [first edition]

Book 4 in the acclaimed Rex Graves Mystery Series A Killer Housewarming in the Scottish HighlandsWhen barrister Rex Graves invites a group of friends to Gleneagle Lodge, he doesn't anticipate the arrival of an old flame--much less a dead body or serial killer. Rex's house-guest and colleague Alistair, who recently made an unsuccessful attempt to convict a man for the notorious Moor Murders, now finds himself under the same roof as the killer. Rex must use his skills of intellect, observation and logic to save Alistair's career and bring the murderer to justice.
