“No surprise there,” he said. “You know what we used to call Heath? Captain Ahab. He gets fixated on something, some whale of a thing, and he will chase it to the bottom of the sea. And he’ll be happy to take all his men with him.”

Don paused. He sighed.

“Listen, Stone, you have nothing to prove to me, or to anyone. You’ve earned a free pass. You can decline this mission. Hell, in a couple of months, you could leave the Army if you want and come join me in DC. I’d like that.”

Now Luke nearly laughed. “Don, not everybody around here is middle-aged. I’m thirty-one years old. I don’t think a suit and tie, and lunch at my desk, is quite my speed just yet.”

Don held a framed photograph in his hands. It hovered above an open box. He stared down at it. Luke knew the photo well. It was a faded color snapshot of four shirtless young men, Green Berets, mugging for the camera before a mission in Vietnam. Don was the only one of those men who was still alive.

“Me neither,” Don said.

He looked at Luke again.

“Don’t die out there tonight.”

“I don’t plan to.”

Don glanced at the photo again. “No one ever does,” he said.

For a moment, he stared out the window at the snowcapped peaks of the Hindu Kush rising all around them. He shook his head. His broad chest rose and fell. “Man, I’m going to miss this place.”

“Gentlemen, this mission is suicide,” the man at the front of the room said. “And that’s why they send men like us.”

Luke sat in a folding chair in the drab cinderblock briefing room, twenty-two other men sitting in the chairs around him. They were all Delta Force operators, the best of the best. And the mission, as Luke understood it, was difficult—but not necessarily suicide.

The man giving this final briefing was Lieutenant Colonel Morgan Heath, as hands-on and gung-ho a commander as there was. Not yet forty years old, it was clear that Delta was not the end of the line for Heath. He had rocketed up to his current rank, and his ambitions seemed to point toward a higher profile. Politics, maybe a book deal, maybe a stint on TV as a military expert.

Heath was handsome, very fit, and over-the-top eager. That wasn’t unusual for a Delta operator. But he also talked a lot. And that wasn’t Delta at all.

Luke had watched him a week earlier, giving an interview to a reporter and a photographer from Rolling Stone magazine, and walking the guys through the advanced stealth and navigational capabilities of an MH-53J helicopter—not necessarily classified information, but definitely not the kind of thing you want to share with everyone.

Stone almost called him on it. But didn’t.
