Division chief of emergency services at UCLA hospital, David Spier is just as horrified as his colleagues when a madman wielding a beaker of drain cleaner attacks an ER nurse who happens to be the sister of an LAPD cop. But when he uncovers the abuse the assailant suffered as a child in a psychological experiment Spier's own mother signed off on decades ago, David puts his career in jeopardy to keep Clyde Slade safe from a policeman bent on vengeance, even after Slade attacks the woman David loves and threatens his life. Gregg Andrew Hurwitz packs the pages with enough medical details and procedures to keep ER fans satisfied until summer reruns are over with this foray into Jonathan Kellerman territory. Spier's no Alex Delaware, at least not yet, but while Hurwitz has a way to go before he approaches Delaware's creator in plotting and pacing, he's on the right track. --Jane Adams
