Malignant Memories - Kassandra Lamb

After two decades in law enforcement, C.o.P. Judith Anderson has seen it all.
Or so she thought... She's more than a little taken aback when a young woman walks into her police department, holds up one of Judith's business cards, and timidly asks if she herself is this Judith Anderson, Chief of Police. The woman has no memory of her own identity nor her past, so Judith turns to her friend, psychotherapist Kate Huntington to puzzle out Jane Doe's history-with only the business card and some droplets of blood on her dress as clues.

The same day, a naked male corpse is discovered in a sleazy motel. Could Jane be the killer? But the pieces don't fit together well, since the victim's blood type is not the same as the blood on Jane's dress.

As Kate coaxes out more of Jane's memories, she and Judith realize there may be yet another connection-to a teenager murdered years ago. Meanwhile, Judith has her own childhood memory surface, which makes this case a lot more personal.

Then Jane further confounds things by escaping from the hospital's psychiatric ward...twice. Who is this woman, a criminal or an innocent? Or perhaps a witness to something that caused her amnesia...and now may have made her a killer's target?
