Bishop Blackie Ryan--who spends more time troubleshooting and solving crimes than he does on spiritual matters--is back in action in a paperback original that's sure to delight Father Andrew M. Greeley's faithful fans. Sent by his boss, Cardinal Cronin, to the nuclear-powered aircraft carrier USS Langley ostensibly to perform a confirmation, Blackie finds that his detecting talents are more in demand than his devotional ones. ("Those of you who have seen the film Pulp Fiction will doubtless remember Harvey Keitel. He was a sweeper, a person designated by God and his betters to sweep up the mess left by higher-ups in the outfit. That's what I am, Sean Cronin's sweeper") Disappearing crew members and other strange occurrences have led to talk of the new ship being haunted, a situation that dedicated debunker of demons Bishop Ryan can't resist.
