Naoki Urasawa's monster 11

Tenma discovers two more pieces of the puzzle to Johan's past in Prague--a story about Johan's mother, a beautiful woman taken away by the secret police, and an old recording of Johan as a child. And Tenma knows all too well that Johan is lurking close by when a brilliant young detective of the Prague Police Department is accused of poisoning three of his superiors...with whiskey bon bons.
