Do No Harm - Hurwitz, Gregg Andrew

A madman assaults nurses at the UCLA Medical Center Emergency Room, but is hurt in another attack and captured. ER chief David Speir treats the assailant. But troubles multiply when the madman escapes. To find him, David delves deep into his patient's mind--a hunt that will lead him into the darkness of his own past.
