What would you do if a child you once saved grew up to be a monster?

An ice-cold killer is on the loose and Dr. Kenzo Tenma is the only one who can stop him! Tenma, a brilliant neurosurgeon with a promising future, risks his career to save the life of a critically wounded young boy named Johan. When the boy reappears nine years later as a cold-hearted and charismatic young man in the midst of a string of unusual serial murders, Tenma must go on the run from the police, who suspect him to be the killer, to find Johan and stop the monster he set loose upon the world. Conspiracies, serial murders, and secret government experiments set against the grim backdrop of the formerly communist Eastern Europe are masterfully woven together in this compelling work of suspense.
