Deadly Care — Leonard S. Goldberg

Dr. Joanna Blalock's specialty is death - but now the fiercely dedicated forensic pathologist has more of it than even she can handle. She has a murder victim without a face to identify, a lengthening list of sudden and suspicious patient mortalities at Los Angeles Memorial Hospital to investigate, and a growing fear that a serial killer is stalking the hospital corridors.
The only one who can help her is her ex-lover, Detective Jake Sinclair, who she thinks has betrayed her. But not even he can protect her when an unseen enemy she cannot escape closes in on her, leaving her nowhere to run. No place to hide. No one to trust...
