Nick Soul: Fallen Angel

A man wakes up in a care unit. Who is he, and how did he get there? He feels no pain, but he's unable to speak or move. Infrequent visits by a "bean counter" named Gabe reveal what he refuses to he's an angel fallen from grace, all the way. He can survive, um, sorry, not in heaven. But he can live in the realm of humankind only by performing a meaningful "mitzvah" or act of retribution. But for what sin? And why in hell should he believe in angels when he knows there is no god?
