The Smokeout of Blackjack

Author of the tell-all about polls has a thing about their MO. Shanghaied, hidden from a blackmailer, all he has to do is write another blockbuster to undo the first book that trashed pollsters. He's also safe from the blackmailer, trying to nail him for a murder. The top cop claims a renegade cop did it. But the street cop suspects the top badge himself whitewashed it. The PI plays on the writer's psyche, moving him to rat on the blackmailer, a relative, swearing, the top gun is the killer-who won't confess.
Media and props from the murder scene roll in to torment him. He can't stand it and befriends a terrorist bomber. The end.
