The Green Wound Contract

What possible connection could Secret Agent Joe Gall find between the man who danced himself to death on the streets of Laredo and the smiling nun who wielded an efficient blackjack in New Orleans? How did a pornographic book in Trinidad tie in with a race riot on the day a Southern town elected an all-Negro government? Who was the mysterious Uncle Tom Asmodeus, who seemed to know each move Joe Gall would make even before Joe got the word himself? Two beautiful women had all the answers - but Joe Gall had to begin asking the right questions, even though he didn't know whom he was fighting.
