“I’ll keep it in mind.”

The man stepped back. “They’ve moved the checkpoint on the other side as well.” He nodded for Mueller to drive on. “Don’t run into that one.”

Mueller put the car in gear, and Hoffner waited until they were out of earshot. “Old friend of yours?” he said.

Mueller remained silent as he continued to stare ahead. He took them down into the town square, where a pious if haggard-looking church stood at one end, immune to the filth and disarray of the skiffs and fishing nets lazing at the other. The sea and the docks opened up beyond them, but there seemed to be no sound coming from the waves. It was just the smell of salt and wet fur. Lines of drying sheets blew in the breeze, but the place was strangely empty. Mueller followed the street up to where the second barricade appeared, just beyond the last of the houses. Another bottle, and they were back on the coast road.

Hoffner said, “They’re not going to win this thing if all it takes is a few bottles of booze.”

Mueller reached for the canteen. “That’s a courtesy, Nikolai.” He had the spout to his lips. “You and I don’t have that piece of paper, we’re lying on the side of the road back there, a single bullet hole through the back of the skull for each of us.” He drank.

“Good that you had it, then.”

“Yes.”

“And they’re selling these pieces of paper in Marseilles?”

Mueller held the canteen out to him. “You haven’t met these boys, Nikolai. These are the true believers. Nothing’s for sale with them.”

Hoffner took a drink. “So you just asked for one and they gave it to you?”

Mueller stared ahead, his smile at once coy and obvious. “Some of us didn’t have to ask.” The road straightened, and Mueller pressed down on the accelerator.

It was nearly an hour before they turned in from the coast, a dirt path that ran through thick grassland dotted with carob, olive, and fig trees. They were heading up toward Montjuic-Jew Mountain, according to Mueller-one of those ancient hills on which ancient cities plant themselves. Mueller had promised a fortress at the top that had seen ancient Romans or Muslims or whichever invading conqueror the Catalans had so bravely sent back into the sea, time and time again. Hoffner had always thought cities like this too comfortable in their pasts to make any present-day swagger seem more than a borrowed vanity: the fading libertine-wrinkled, bronzed, and smelling of a too-sweet cologne-drawing strength only from memory.

And yet it wasn’t all that long ago that the hill had known sheep and cows and goats and, somewhere off in the distance, those long stalks of yellow wheat that a woman could thresh and grind into whatever might keep a family alive: twelve hundred years of tradition rooted out by a city once again desperate to move beyond itself. The world had come to Barcelona in 1929, and sheep and cows and goats were not what the world was meant to see. Instead, it was a mechanical fountain that swayed under the lights; a grand palace to rival any of the most lavish in Europe; pavilions to tease with tastes of Galicia, Valencia, and Andalucia; and views of the city to make even the worst kind of frippery seem worthwhile.

The World’s Fair had transformed Montjuic, or at least that part of the hill which faced the city. It was now a glowing tribute to Barcelona’s past, present, and future. For Hoffner, though-coming up on it from the backside-it was little more than a rise of brush and thick trees, with a few tracks leading nowhere.

“Bit of a risk, leaving the car up here,” Mueller said, as he downshifted and willed the old sedan up the slope. They were well into the tree cover now, grateful for a respite from the sun. “We’ll do a little painting before we go. Find it a good spot.”

It was impossible to mount Montjuic head on. Instead, they lumbered up one of the slaloming paths until, about fifty meters from the top, they stopped. Mueller pulled up hard on the hand brake before stepping out to find a few rocks. He wedged a handful behind each of the wheels and then headed back to the boot.

Hoffner was lighting a cigarette as he gazed up the hill.

“Smells like sugared beets,” he said.

“Does it?” Mueller found a small jar of something and placed it on the fender. He went back to his rummaging.

Hoffner said, “At least the sun’s not making it through here.”

“At least.” Mueller reappeared with a small paintbrush and limped around to the side of the car.

“The path’s still good,” said Hoffner. “We could take it up a bit farther.”

“We could.” Mueller knelt down. “If you like cracked axles and blown tires. We’d also hit the cliff. At least that would make it easier coming down.”

Mueller unscrewed the top of the jar. Mixing the paint with the brush, he began to slather the doors in some sort of design. Hoffner tried to decipher it upside down, but the dripping made that impossible. He got out on the driver’s side and stepped around the car.

It was letters: CNT-FAI.

“Anarchist trade union,” Mueller said, admiring his work. “Leave it to the Spanish to unionize the one group bent on tearing the whole works down. ‘Don’t like anything that smacks of organization? Come, join our organization…’ ” He took some water from the canteen and washed off the brush. “Must have a hell of a time collecting dues.”

When he had everything back in the boot, Mueller closed it and started up the hill. Hoffner had no choice but to grab the rucksack and follow.

“So you just leave it there?” Hoffner said, doing what he could to adjust the ropes on his shoulders. “No one touches it?”

Mueller nodded without turning. Even with the limp he was putting distance between them.

Hoffner said, “A few letters on the side and everything’s fine?”

Again Muller nodded.

When Hoffner began to feel it in his legs, he said, “So why didn’t we paint it in the first place, avoid the hill altogether, and just drive into town?”

Mueller continued to walk. “Right foot giving you a little trouble, Nikolai? Tough going on the rocks and roots?”

“I was just asking.”

Mueller slowed, then stopped. He looked up as if he were thinking something through. Hoffner took the opportunity to stop as well. “Why didn’t we drive into town?” Mueller said. “What a good question.” He looked back at Hoffner. “You’d think a cripple would be smarter than that.”

Hoffner started walking again. “Fine. There’s a reason. Just walk.”

Mueller let Hoffner pass him before saying, “You don’t want to be driving a car into Barcelona these days, Nikolai. They’ll either take it and burn it or pull you out so they can beat you before they take it and burn it.”

“And they do this to people who have those mysterious pieces of paper?”

“A car requires a different piece of paper,” Mueller said, as he started up the hill again. “So we walk.”

A small falcon hovered high on the wind ahead of them, its head pressed down, before it banked and sped toward the ground.

They were beyond the trees now, almost to the top, where the grade of the hill grew steeper. Off to the right Montjuic was sheer cliff, two hundred meters of rock face to the sea. Hoffner wondered if the bird might somehow misjudge the sudden rise-fail to pull itself up in time-but that would have required a different kind of instinct, a daring built on fear. It was the bird’s effortlessness that saved it from anything human. The wings came within a half meter of the ground and swept up again, with something small and wriggling caught in its talons.

“They like the rocks and the fortress,” Mueller said, as he brought them to the summit. “Kestrels. Don’t know what it is in Spanish.”

“Cernicalo,” Hoffner said. He had no idea how he remembered it.

Mueller was only mildly impressed. “Smart little birds. Rats never see them coming.”
