While private investigator (P. I.) Morgana (Morg) Mahoney carries a Colt .38 revolver in her purse, her sharp tongue and quick wit are just as lethal weapons. She and her filthy rich, drop-dead gorgeous friend, Heather, leave sunny Southern California for a manor house in northern England to celebrate Christmas.

What begins as a vacation, or holiday as they say in the British Isles, soon becomes a murder mystery laced with threads of local history, race horses, the IRA, family secrets, a touch of romance and, of course, pure greed.
