Key to a Murder — Vicki Vass

A mysterious woman appears on the doorstep of Great Aunt Sybil's Attic in the middle of the night. Owner Anne Hillstrom lets her in, only to have the woman die in her arms. With no final words, and only an old lantern clutched to her chest, the dead woman provides Anne and her partner CC precious few clues to discover her murderer or why she spent her last moments in their antique store. The two Antique Hunters search for clues, finding themselves entangled in a centuries-old mystery leading them to a cemetery in Ireland where a ghost from the past has left them a cryptic message, and a killer has left them no choice but to discover his identity before he kills again. On their journey, the two best friends encounter antiques, romance and the key to a murder. Key to a Murder is the fourth book in the Antique Hunters Mystery series.
