His battered Volkswagen was parked over on Newhall Street, and he had just turned onto Colmore Row when the driver’s-side window of a sleek Jaguar sedan whispered down.

“Dr. Cantor, might I have a word?” The voice was cultured, with a continental accent—French, German, maybe Swiss, which to Cantor sounded like a combination of the two.

“Ah, I don’t have my doctorate yet,” he stammered when he recognized the black shirt and tie of Dark Suit sitting behind the wheel of the luxury sedan.

“No matter, you gave a compelling speech. I would have stayed for the rest, but I received a call I couldn’t ignore. Please, just a few moments, is all I ask.”

“It’s raining.” Bending to peer into the car sent a spike of pain through Cantor’s strained sinuses.

“Not in here.” The man smiled, or at least his lips parted and his teeth were revealed. “I can drive you to your car.”

Cantor looked up the street. There was no one about and his car was five blocks away. “Okay.”

He stepped around the long sloping bonnet and heard the electronic lock disengage for the passenger seat. He slid into the supple leather. In the glow of the dash lights, the sedan’s considerable woodwork shimmered.

The stranger slipped the car into gear and eased it from its parking space. The Jag was so smooth that Cantor hadn’t realized the engine had been running.

“An associate of mine heard the lecture you gave last week in Coventry and was intrigued enough to tell me about it. I had to hear for myself.”

“I’m sorry, you are?”

“Oh. My apologies. Tony Forsythe.” They shook hands awkwardly since Forsythe had to reach under his left arm so as to not release the steering wheel.

“And what’s your interest in Marco Polo, Mr. Forsythe?” Cantor asked.

He got an odd vibe from the man. He was around forty and had plain, unexceptional features, yet thick dark hair that was so dense it could have been a toupee. Still, there was something else. Cantor realized what it was. His hands had been large and callused. His grip hadn’t been overly forceful, but Forsythe’s hand had practically swallowed Cantor’s. In his experience, men in £1,000 overcoats and £60,000 cars didn’t have calluses.

“I’m a dabbler in history, you might say, and I’m interested in this folio and its contents.”

William Cantor had looked for a fish, but he had the sudden feeling he’d nabbed a shark. “Um, I’m down Newhall.”

“Yes, I know,” Forsythe said, which rather bothered Cantor, but the stranger added, “Have you there in a jiff. You mentioned the folio’s owner had no interest in selling, correct?”

“Yes, the man’s loaded. I think he asked me to pay to see his library just to get under my skin.”

“But no price was discussed?”

“Ah, no. It was all I could do to come up with the five hundred quid to see the damned thing for a day.”

“Pity,” Forsythe said almost to himself. “A simple cash transaction would have been preferable.”

To Cantor’s relief, the Jag made the left-hand turn onto Newhall.

Forsythe glanced at him for a second. “I don’t suppose you’d be willing to tell me the gentleman’s name?”

“I, ah, I don’t think that would be in my best interest, now would it?”

“Oh, but it would, friend William. It is most certainly in your best interest.”

The Jaguar suddenly leapt forward under hard acceleration. Cantor got a fleeting glimpse of his blue VW Polo as they raced past. “What the bloody hell do you—”

The arm of a person who’d been lying flat and unseen in the spacious rear seat snaked around Cantor’s neck with the strength of an anaconda, choking the words in his throat. A sharp jab to the neck, a strange metallic taste in his mouth, and three seconds later William Cantor slumped over in drug-induced unconsciousness.

With his parents long dead from an accident on the M1 and no siblings or a girlfriend, it wasn’t until his landlord knocked on the door to his tiny one-room flat a month later that anyone knew Cantor had gone missing. The handful of presentations he’d planned had been courteously postponed by a person claiming his identity. It would be another several days before a missing persons report was matched with the headless and handless corpse found floating in the North Sea of the fishing town of Grimsby about that same time.

There were two things on which all the police involved agreed. The DNA found in Cantor’s apartment matched that of the body fished from the water. The second was that before the man died he’d been tortured so severely that death would have been a blessed relief.

Because Cantor kept all his notes on the Rustichello Folio in his briefcase, which was never recovered, there was one more crime the authorities never realized was related to his disappearance. There had been a botched break-in of a Hampshire estate down in the southern part of the country near a town called Beaulieu. It happened two days after the last confirmed Cantor appearance. Forensic reconstruction showed that the burglars had been surprised by the widower owner during the robbery, bashed him over the head with a jimmy bar left on the scene—no prints—and fled in panic, not even bothering to take the pillowcases stuffed with sterling silverware they’d already gathered.

None of the police gave a second look at the slim gap in the rank upon rank of books that lined the estate’s paneled library.

TRIBAL REGION

NORTHERN WAZIRISTAN

TODAY

THE MOUNTAIN VILLAGE HADN’T CHANGED IN TWO HUNDRED years. Except for the guns, of course. They had long been around, that wasn’t the issue. Rather, it was the type of weapon that had changed. Centuries ago, the bearded men toted bugle-throated blunderbusses. Then came the Tower muskets, followed by the Lee-Enfield rifles, and finally the ubiquitous AK-47s, which flooded into the region thanks to the Soviet invasion of Afghanistan, to the north. And so good were these guns that most were older than the men who carried them. Didn’t matter if he was defending the region from a rival faction or heading off to the outhouse, a man without an AK at the ready was no man.

All this ran through Cabrillo’s mind as he watched two Pashtun youths from the north, kids barely out of their teens, their beards just shadowy stubble on chin and cheek, try to wrestle a pair of goats onto an open-bed truck. All the while the assault rifles slung around their shoulders would slip and go across their chests, hitting the animals hard enough to make them fight the manhandling.

Each time a gun slipped, the boy would have to pause and redirect it back over his shoulder and then try to calm the satyr-eyed goat. The distance was too great to hear, but Cabrillo could imagine the goats’ frightened bleats and the young men’s earnest pleas to Allah for easier ways to handle livestock. It never occurred to them to rest their rifles against the rickety stockade fence for the sixty seconds it would take to load the animals unencumbered.

Take away the forty or so other armed men in the village encampment and he would have found it comical.

He had to admire the kids for one thing. Though he was ensconced in the latest arctic gear, he was still freezing his butt off while they cavorted in a couple of layers of homespun woolen clothing.

Of course Cabrillo hadn’t moved more than his eyelids in the past fifteen hours. And neither had the rest of his team.

In Northern Waziristan, it was traditional that villages were built like citadels on the tops of hills. What grazing and farming was available was accomplished on the slopes leading to the town. In order for him and his people to find a suitable observation post that let them look down on the Taliban encampment, they had to find cover on an adjacent mountain. The distance across the steep valley was only a mile, but it forced them up a snow-and-glacial-ice peak and left them struggling to draw breath at almost ten thousand feet. Through his stabilized binoculars, he could see a couple of old men smoking a never-ending chain of cigarettes.
