Naoki Urasawa's Monster, Volume 2: Surprise Party (Naoki Urasawa's Monster, #2)

An ice-cold killer is on the loose, and brilliant Dr. Kenzo Tenma is the only one who can stop him! Conspiracies, serial murders, and a scathing indictment of hospital politics are all masterfully woven together in this compelling manga thriller.

Tenma springs to action when he discovers that Johan, the boy whose life he saved nine years ago, has grown up and turned into a serial killer. But when Tenma finds out that Johan has strong inside connections with government officials, he realizes that this monster is far more powerful than he could have ever imagined.
