From: The Darker Mask. Ed. Gary Phillips and Christopher Chambers. Tor, 2008.
This story from a anthology of noirish superhero tales is told in the frenetic, poetic stream of consciousness of a crack addict who kills a priest to steal from a church poor box. After this encounter, he gains the power to travel through time, taking the sins of others as his own, clearing their paths to heaven while he is cursed with immortality on earth. A Deity with an Irish brogue calls him the Absolver.
