The policeman who had grabbed him down the street came puffing up as others were snapping manacles onto Hale’s wrists and rifling his pockets. “If your name,” the man wheezed angrily, “isn’t-bloody Hale, I’m going to thrash you-right here on the church steps.”

“The name’s-in my notecase,” panted Hale. He could hear the van accelerating in reverse, audibly weaving in the lane as it came fast the wrong way up King Street in the dark. Had there been nobody else to arrest? “Andrew Hale.”

Makes you wonder why we still bother.

Hale had started to slant his stride to the right, away from the direction Theodora was taking across the wet grass of Green Park, and after a moment he realized that this was the old training kicking in; the plot here said that he had given an elderly stranger advice to do with the map, and that the two of them didn’t know each other, weren’t together. Hale squinted to the right, as if considering walking west toward Hyde Park Corner tube station, but dutifully kept the figure of the old man clearly in his peripheral vision.

Now Theodora reached up with his gnarled left hand and took off the black homburg. Even out of the corner of his eye Hale could see the spotty bald scalp and the neatly styled white hair, so different from the black locks he remembered seeing as a boy; and he nearly didn’t notice the signal-the old man had whirled the hat on one finger before flipping it back onto his head. Get in the car, that move meant.

“Not so fast,” Hale whispered through clenched teeth. These were real enemy-territory contact procedures, and for the first time in many years he was experiencing the old anxiety that was somehow more immediate than fear of capture-don’t slip up, don’t let down the side.

Beyond the beech trunks ahead, he could see vehicles driving east down the lanes of Constitution Hill, all their colors drab on this gray day. Keep your pace steady, he told himself. Don’t try to help. They’ll have got this timed.

This? he wondered helplessly. What, did Khrushchev only pretend to back down from Kennedy’s ultimatum about the Cuban missiles two months ago, have all the legal Soviet and Sov Bloc residencies disappeared from their embassies at once, gone covert and illegal, is war the next card to be dealt? But why are we miming? Or has there been some sort of in-house coup at SIS, so that old peripheral agents are being reactivated and concealed from the present victors? Am I in a faction here?

When he passed the bordering trees and stepped off the grass onto the pavement, the old man was an anonymous figure twenty yards away to his left, and Hale just hoped no more signals were being given. When Hale paused at the curb-even as he shrilly wondered, What car?-a blue Peugeot sedan came grinding up to rock to a halt right in front of him. The passenger-side door was levered open from inside, and he bent over and climbed in; and the car had pulled away from the curb even before he had yanked the door closed.

The driver was a thin woman with iron-gray hair, and he thought he recognized her chin-up profile from the fourth-floor offices at Broadway during the war. He knew better than to ask.

“There’s a jacket on the floor,” she said. “When I dogleg through Pall Mall, ditch yours and put it on. Not now.”

She made a fast but controlled left into the narrower corridor of Basingstoke Road and sped between the briefly glimpsed gray stone porticoes of St. James’s Palace and Lancaster House, and then turned left again into the westernmost block of Pall Mall. Hale was gripping the strap on the inside of the passenger door.

“Now,” she said, her gaze darting from the cars ahead to her mirrors and back as she juggled the Peugeot rapidly across the lanes. “Glasses and a moustache in the jacket pocket.” Hale smiled nervously at the notion of a false moustache, but his face went blank when, after a beat, she added, “Iron anchor in the inside pocket.”

He heard his own voice say, “Shit.” With his feet braced against the floorboards he shrugged out of his coat without conspicuous contortion, wondering remotely if he would ever get the coat back and if his test questions would still be in the pocket if he did, but his attention was on the gray wool jacket he now snatched up from the floor; he squeezed the lapel, and even through the cloth his fingers found the heavy iron shape of the looped Egyptian cross, properly called an ankh. And he was bleakly sure now that the route his driver was tracing would be widdershins, a counterclockwise circle, and that it would loop right around Buckingham Palace to end in Whitehall.

“And lose the tie,” she said. “You’ll be getting on the back of a motorcycle pretty prompt here.”

They were speeding up St. James’s Street now, past gentlemen’s hat and shoe shops, but as he obediently pulled loose the knot of his tie, Hale didn’t look out through the windscreen nor at his driver; he was staring blindly at the fascia panel, remembering the ankhs that had failed to work as anchors for the men he had led up the Ahora Gorge below Mount Ararat in ’48, on the night that the starry sky had spun like a ponderous unbalanced wheel over their doomed heads. He was certain now that this new year’s business would have nothing to do with any recognized Soviet residents in London, nor with factions that could possibly still be on the active force at SIS.

He pulled his necktie out of his collar and undid the top button of his shirt. “I wish I could ‘lose the tie,’” he said, his voice sounding childish and frightened in his own ears.

This was going straight back to what had been the most-secret core of espionage in the first half of the century, the hidden power he had become dimly, fearfully aware of only in the last three and a half years of his service, after Berlin in ’45; the operational theater that it had been mortally perilous even to know about, more restricted by far than the German Ultra traffic had been during the war, or the Soviet Venona decrypts after; this had been the concealed war that, ironically, facilitated its own concealment simply by being beyond the capacity of most people to believe.

Like someone tonguing a carious tooth to see if it still ached, he asked himself if he still believed it.

He sighed finally and focused on the traffic, and then glanced around to be sure they were in fact passing the Tory Carlton Club, and Brooks’s. “They let buses drive in St. James’s Street now?” he asked.

“Just in the last year or two,” said the woman at the wheel.

He remembered Theodora saying, I hardly know where I am in London these days. Me too, Jimmy, he thought. And how do you suppose things are in Erzurum, Al-Kuwait, Berlin? Even Paris?

He was to learn later that the old police station in Temple Lane had been exploded across the flower beds of the Inner Temple Garden by a November bomb; but even at nineteen and in the dark he had known at once that the dimly seen hut he’d been driven to in the police van was a wartime makeshift. Its roof was a semicircular arched sheet of corrugated metal, and as he was marched up to the door, he saw that the building sat like a sled on bolted steel beams in the middle of a patch of cleared pavement, a hundred yards from the pillared entry arch and raking cornices of St. Paul’s Cathedral-the big St. Paul’s, at this end of the ride, Christopher Wren’s masterpiece, its dark dome seeming to eclipse a full quarter of the cloudy nighttime sky.

And even in his despairing panic he shivered at the sight, for he had motored past St. Paul ’s Cathedral when he had been a student at the City of London School-and only the top of its dome had been visible then above the close-crowding newer buildings. Now it stood alone in the center of a bomb-cratered plain of low uneven walls, itself miraculously undamaged, like a durable mirage from a previous century.
