Knox sat in a chair and said, “You were a piece of crap for pulling the plug on it just because he wouldn’t follow your order to slaughter an innocent village in Nam.”

“I know that now. I’m sorry. I should never have given that order.”

Stone stopped next to the quaking Hayes and looked him up and down, apparently deciding on the best place to deliver the lethal blow.

Knox added, “And you shouldn’t have come up to that prison and made a deal with that warden to keep me there because I’d found out the truth.”

Stone was now holding the knife against Hayes’ throat.

“I’ve dreamed about this for nearly forty years, Mack,” said Stone.

“Knox,” wailed Hayes. “I’m begging you. I’m sorry for what I did at the prison. I never should have left you there. I’m sorry. For God’s sake make him stop.”

“Okay,” Knox said. “Oliver, go ahead and stop.”

Stone stepped back and flipped the knife to Knox, who pulled out a walkie-talkie and said into it, “Okay, come on in.”

Five men came rushing through the door seconds later and strode up to the still cowering but confused-looking Hayes.

One of the men said, “Macklin Hayes, you’re under arrest for obstruction of justice, false imprisonment, war crimes, covering up a drug ring, conspiracy to commit same and for using government property to blow up a civilian car in a public place resulting in reckless endangerment.” The man then gave him his Miranda warning.

Knox pulled out a DVD from his pocket and tossed it to Hayes. “You can share that with your lawyers.”

Hayes looked down at it. “What the hell is it?”

“The place where you met with us at the prison and told us everything because you figured we’d never get out? It was an interrogation room, you dumbshit. Warden up there was real keen on surveillance. There was a hidden camera and it recorded every syllable you said.” He looked at the men. “Take his ass away. I’m sick of looking at him.”

As they pulled Hayes from the room in cuffs, he screamed, “That man is John Carr. He killed Carter Gray and Roger Simpson. Arrest him, arrest him right now.”

One of the men said, “Shut up!” and then pushed Hayes out the door.

After they were gone, Knox and Stone left the house and walked down the dark, quiet, lamplit streets of Georgetown as a chill wind blew in off the nearby Potomac.

“You know,” Knox said, “Hayes was the only one who was after you. I reported only to him. He was doing this on his own authority, it wasn’t an Agency thing.”

“He’s a man who holds his grudges,” agreed Stone.
