The Devil's Door - A Catherine Levendeur Mystery (Paperback, 1st pbk. ed)

1140 Anno Domini:
A wealthy countess lies dying at the Convent of the Paraclete, brutally beaten by unknown assailants. Despite entreaties, she is unwilling to name her killer. Beautiful Catherine LeVendeur, the Paraclete's most learned young novice-scholar, vows to find out the identity of the woman's attacker.
When her beloved Edgar comes to lead her from the convent to a life of the flesh, Catherine is torn between her quest for justice and the pledge she made him. Catherine doesn't want to break any of the vows she's made-and if she abandons her crusade for the truth, others will die, and the convent she loves may be destroyed...
