Showing Legend in Green Velvet by Elizabeth Peters

Scotland is Susan's passion and obsession--and the opportunity to join a Highland dig is a dream come true for the young archaeology student. But then a sinister stranger slips Susan a cryptic message and is later found viciously slain. A mysterious peril has emerged from the mists to haunt Susan, sending her running for her life in the company of handsome, unconventional laird Jamie Erskine. For she has an unseen enemy hiding in the shadows--someone who, for some unknown reason, is going to great lengths to frame her for murder . . . and to bury Susan, if necessary, in this land she loves.
