Ichabod Jones: A psychopath's work is never done

A psychopath escapes from an asylum and becomes a monster hunter during the apocalypse with the unwelcome help of the voice in his head. This is a story about perception. Throughout the whole story we don't know if Ichabod is really in the Apocalypse, if it's all in his head, or if he's killing real people and just thinks they are monsters.
