After about fifteen minutes they rounded a bend in the river and spotted a string of lights that, according to the GPS, marked Saddam’s private dock. The dock spanned nearly a hundred meters of waterfront and terminated at its east end in a riverside party and guest house that was larger than most people’s primary homes. The house also contained a guard station, so Mustafa steered well clear of it, continuing upriver past the dock’s west end before killing the launch’s running lights and doubling back. He brought them in on the lowest throttle setting, finally cutting the engine entirely and coasting into an open berth beside a yacht named Bint Zabibah.

“Now what?” Samir said, after they’d tied off the launch.

“You remember back in ’97, when Halal was planning to raid this place?” Mustafa asked.

“I remember the judge denying us a warrant after our informant turned up in a cement mixer.”

“Yes, but before that, when the mission was still a go, I had a good look at the blueprints and reconnaissance photos. The main way up to the estate is through there”—he gestured towards the party/guard house—“but there’s also a separate gate above a slipway at this end, for putting boats into and out of the water—and loading liquor onto trucks. That gate’s not so well guarded, and at the time it was secured only with a padlock and chain.”

Amal was already rummaging in the launch’s toolbox. “Will this do?” she said, holding up a pair of long-handled bolt cutters.

They put their goggles and face masks back on and stepped out onto the dock. The gate was where Mustafa said it would be, but unlike Halal, Saddam had upgraded his security since the 1990s. A video camera had been mounted above the gateway, and the gate itself was now a solid sheet of metal, barred and bolted from the inside.

“What about going over the wall?” Amal suggested, as they huddled out of the camera’s view. “We can use the bolt cutters on the barbed wire.”

“It’s got to be at least four meters high,” Samir said. “You have a grappling hook, too?”

“If we can pile up some boxes or something for you to stand on, you can give me a boost.” Reading their silence as discomfort rather than skepticism, she added: “Pretend you’re my brothers.”

No one had a better idea, so they crept along the dock looking for some boxes or crates strong enough to bear their weight. Just past the Bint Zabibah they found a small, wheeled dumpster chained to a post. They cut the chain and trundled the dumpster back to the slipway.

Mustafa was the tallest of them, so he stood on the dumpster lid and let Amal climb up on his shoulders. Samir stayed on the ground trying to hold the dumpster steady. This circus act would have been difficult even in perfectly calm weather and under these conditions should have been impossible, but the wind was oddly cooperative. More than once, as she stretched to cut the strands of barbed wire, Amal felt herself starting to overbalance, only to have a sudden gust like a firm hand push her back against the wall. She worked as quickly as she could. When the last strand parted, she tossed the bolt cutter to the ground and said, “OK!” Mustafa placed his hands under the soles of Amal’s shoes and pushed up, hard. This maneuver proved too much for the dumpster lid, which buckled beneath him and sent him tumbling back to be caught by Samir—but when they looked up, Amal had vanished over the wall.

Five long minutes later, the light on the security camera went out and the gate opened. Amal, now armed with an assault rifle, waved them inside. They passed through a short tunnel. At the other end was a guard shack, inside which a Republican Guardsman lay, bound hand and foot with plastic zip-ties and blindfolded with his own jacket. Mustafa turned to ask Amal a question but she was already forging ahead.

They made for the lights of the main house. They’d covered about half the distance when the wind dropped almost to nothing, and they heard, somewhere off to the left, the asthmatic roar of a lion. This was followed by another, softer wheezing sound. A Republican Guard staggered out of the haze, gasping for breath, and fell facedown in front of them.

While Amal kept watch for the lion, Mustafa and Samir bent down over the Guard. The man hadn’t been mauled; he’d been stabbed. A handmade plastic blade had been driven into his upper back, piercing a lung. Mustafa pulled it loose and squinted at the legend on the side of the shiv: XBOX 360.

From behind them they heard the sound of a pump shotgun being cocked. “Don’t move!” said a voice. The words were Arabic, but the voice was American . . . and familiar.

Mustafa spoke without thinking: “Captain Lawrence?”

“Stand up slowly,” the voice said. “Now all of you turn around. Slowly.”

The captain’s T-shirt was torn and bloody, and a chunk was missing from his left ear where one of his dying jailers had bitten him. Looking at him, Mustafa experienced a curious sense of doubling. He felt like he knew this man, had worked with him for years. He knew that he didn’t know this man; they’d never met before. Not in this life.

Without waiting to be told, Mustafa lifted his goggles up to his forehead and tugged down the rag that covered his nose and mouth. The captain lowered the shotgun. “Mustafa?”

“Hello, Captain Lawrence,” Mustafa said. “How is Operation Iraqi Freedom coming?”

The window of the prayer room had been shuttered against the storm and the sand pattern on the floor had been redrawn. A chair of hammered black iron held the captive jinn at the center of the circle. Saddam stood facing the jinn, while Mr. Rammal orbited them both. The sorcerer had donned a peaked cap of densely woven silver thread, and as he walked around the circle with the brass bottle held before him, he muttered incantations in the dead language of Babylon.

Bearing witness to the ritual, their faces lit by flickering torchlight, were Qusay, Uday, Abid Hamid Mahmud, Tariq Aziz, and a half-dozen Republican Guard. The Guardsmen remained impassive—all except for one, who grew increasingly uncomfortable with the blasphemy being committed here and finally opened his mouth to protest. But Uday silenced him with a glance.

Mr. Rammal completed his ninth circuit. He removed his cap and gave the bottle to Saddam, who hefted it in both hands, weighing it like a newborn.

Saddam Hussein addressed the jinn: “Are you ready to do my bidding?”

The jinn stared back at him placidly. “Tell me what it is you want.”

Saddam passed the brass bottle back to Mr. Rammal and snapped his fingers. Abid Hamid Mahmud came forward and handed him a globe. Saddam showed it to the jinn; black marker had been applied to the globe’s surface, changing borders and renaming nations. “I also have some notes,” Saddam said, patting the breast pocket of his uniform. “Perhaps you’d like to study them.”

The jinn flexed his wrists beneath the iron bands that held him to the chair. “That’s all right,” he said. “I believe I understand. You wish to be a ruler again. Arabia will be the seat of your power. From there, your armies will march out, victorious, over Persia and India, Europe and America, and all the rest of the world. Your old enemies will be found and brought to you in chains, to be humbled before you. And you will be the king of all kings, now and forever. Does that about cover it?”

Saddam Hussein grinned. “That will do for a start.” He tossed the globe back to Abid and spread his arms to embrace his future. “You’ve heard my wish,” he said. “Now give it to me! I command you!”

“Very well,” the jinn said. “My answer is no.”

The three Guardsmen stood shoulder to shoulder at the window of the front gatehouse, peering out into the storm.

“It’s not natural,” said the first Guard.

“Fuck you, it’s not natural,” said the second.

“Look how dark it’s getting!”
