Profundis — Richard Cowper

Tom Jones is naïve, impressionable and very, very willing. His chief talent is conversing with dolphins in the Aquatic Mammals Division of HMS Profundis, a gargantuan submarine destined to roam the ocean depths for a century following the nuclear holocaust.

Years pass and mad captain succeeds mad captain. Eventually the ship falls under the command of one Admiral Prood, a kind, understanding man who finally comes to a startling conclusion. He is God the Father. The Almighty Himself. And all he needs now is a son to sit at his right hand.

Enter the innocent Tom Jones.
