Naoki Urasawa's Monster Volume 7 (NAOKI URASAWAS MONSTER GN)

Tenma's on the run! A wanted man, he's the prime suspect for the serial killings he's trying to stop. But he still manages to edge closer to discovering more about Johan's mysterious past, and everything seems to point to a now defunct institution of East Berlin--an infamous "experimental" orphanage called 511 Kinderheim!
