1777: Landon Mansion is commandeered by British Lord "Butcher" Bedford. He stabs Lucy Tarleton, who spurned his king and his love, leaving her to die in her father's arms. Now: Docent Allison Leigh, while locking up, finds a colleague slumped over Bedford's desk, impaled on his own replica bayonet. Allison is indignant at the prospect of "ghost hunters" investigating this apparent murder. Agent Tyler Montague knows his hauntings and his history. Then a second mysterious murder occurs. Wary, yet deeply attracted, Allison has to trust Tyler and work with him to discover just what uninvited guest has taken over the house.
