Hunting the Witch by Ellen Hart

Jane Lawless has a knack for cooking and a talent for detection. A case gone bad has left her with a serious head injury and vulnerable enough to accept help from former lover Dr. Julia Martinsen. The TLC is welcome—if only Jane didn’t suspect the jittery Julia of hiding something. Disquieted, Jane’s check into the doctor’s past turns up chilling details. Then a shocking death and swirling danger disrupt what’s left of Jane’s recovery, and being in love with Julia doesn’t protect either of them from a killer out for more blood.
