“But how do we proceed?” Anton asked. “This is the only road heading south.”

“You will have to turn around,” said the officer. “Go back the way you came. Eventually, you will reach a crossroads. From there, you can go north. And then”-he rolled his hand in the air-“after some hours, you will find another road heading east.”

“Hours?” shouted Kirov.

“Yes, so the sooner you get started…”

Anton rummaged in the pocket of his tunic.

As he did this, the second guard reached slowly down and undid the flap on his gun holster.

Anton removed a sheaf of orders typed on thin, waxy paper, grayishly transparent, the last one signed at the bottom with ink which had soaked through the page. “Read this,” he said.

The officer snatched the papers. He glanced at each of the three men in turn.

The Emka’s engine burbled patiently, filling the air with a smell of exhaust.

The second guard leaned over the officer’s shoulder, reading the orders Anton had given them. He made a faint choking sound. “The Emerald Eye,” he said.

One late September afternoon, Pekkala was summoned to the Catherine Palace, which was on the grounds of the Tsarskoye Selo estate.

Pekkala arrived late. That afternoon, in Petrograd, he had testified at Grodek’s trial. The hearings lasted longer than expected. By the time the tribunal had released Pekkala from the witness stand, he was already overdue.

He guessed that the Tsar would not have waited up, but would already have returned to his quarters for the night. Without any way to confirm this, and with no idea what the Tsar wanted, Pekkala decided to make his way to the palace. In his two years as the Tsar’s Special Investigator, he had often been summoned without knowing the purpose of his visit until after he arrived. The Tsar did not like to be kept waiting. He was a man of disciplined habits, his days rigidly scheduled between meetings, meals, exercise, and time with family. Anyone who upset this balance was not dealt with kindly.

To Pekkala’s surprise, the valet who met him as he entered the Catherine Palace explained that the Tsar had waited after all. The next surprise came when the valet told him the Tsar was expecting him in the Amber Room.

The Amber Room was unlike any other place on earth. Pekkala had heard it described as the Eighth Wonder of the World. Few people outside the immediate family were allowed inside. It was not a large room, a little over six paces wide by ten paces long and the height of two tall men. Nor, in comparison with other rooms in the Catherine Palace, did it have the most spectacular view from the windows which lined one of its walls. What made the room remarkable was the walls themselves. Covering them from floor to ceiling were panels inlaid with over half a million pieces of amber. Wooden mosaics on the floor mirrored this dizzying collage of fragments, and a glass case in the corner contained trinkets made from the fossilized sap-cigar cases, music boxes, hairbrushes, an entire chess set whose pieces were carved from amber.

When light poured through the windows, the walls would glow as if they were on fire, radiating heatless flame from somewhere deep inside. At moments like this, the amber appeared to be like a window into a world of perpetual sunset.

In spite of finding himself so often surrounded by the priceless possessions of the Tsar, Pekkala did not covet them. He had grown up in a house where beauty had been found in simplicity. Tools, furniture, and cutlery were appreciated for their lack of frivolousness. To Pekkala, so much of what the Tsar owned struck him as merely impractical.

Pekkala’s lack of interest in such wealth confused the Tsar. He was used to people being jealous, and the fact that Pekkala didn’t envy him troubled the Tsar. He would try to interest Pekkala in the ivory and ebony inlay of a desk, or a damask-barreled set of dueling pistols, even going so far as to offer them to Pekkala as gifts. Pekkala usually refused, accepting only small tokens and then only when the Tsar would not take no for an answer. In the end, it was the Tsar who envied Pekkala, and not the other way around, not because of what the younger man had, but because of what he did not need.

But the Amber Room stood apart from all the other treasures of the Tsar. Even Pekkala could not deny the spell it cast on those who saw it.

As he passed through the White and Crimson Dining Rooms, Pekkala noticed a tall man in military uniform emerging from the Amber Room. The man closed the door behind him and, with a spring in his step, strode through the Portrait Gallery.

As the man approached, Pekkala recognized the close-tailored uniform and slightly bowlegged gait of a cavalry officer. The Major’s face was thin and accented by a rigid waxed mustache.

He walked right past Pekkala without so much as a greeting, but then he seemed to change his mind and he stopped. “Pekkala?” he said.

Pekkala turned and raised his eyebrows, waiting for the man to identify himself.

“Major Kolchak!” said the man, his voice louder than it needed to be in the gallery’s confined space. He held out his hand. “I’m glad we have a chance to meet.”

“Major,” said Pekkala and shook his hand. He did not want to offend the man by admitting that he’d never heard of him before.

“You are expected, I believe.” Kolchak nodded towards the Amber Room.

Pekkala knocked at the door and walked into the room.

Without the sunlight through the open windows, the amber walls seemed mottled and dull. In the half-light, the polished surfaces made the walls appear wet, as if he had stumbled into a cave and not a room inside the Catherine Palace.

The Tsar sat in a chair by the window. Beside the chair stood a small table, on which a candle burned in a holder. The holder was shaped like a dog howling up at the moon, with the candle clenched in its teeth. Two books lay neatly stacked beside the candle.

Only in that sphere of the candle’s reach did the amber seem to glow. The Tsar himself appeared more like an apparition, floating in the darkness. On his lap was a stack of documents-a common sight, since he acted as his own secretary. This meant that, in spite of his fastidiousness, the Tsar was often overwhelmed with paperwork.

“You met Major Kolchak?” asked the Tsar.

“Briefly,” Pekkala replied.

“Kolchak is a man of great ingenuity. I gave him the unusual task of protecting my private financial reserves. In the event of an emergency, he and I have arranged to hide them in a place where, God willing, they will not be found until I need them.” The Tsar lifted the stack of documents and let them fall with a slap to the floor. “So,” he said. “You are late.”

“I apologize, Excellency,” said Pekkala, and was about to explain why when the Tsar cut him off.

“How was the trial?”

“Long, Excellency.”

The Tsar gestured towards the two books. “I have some things for you.”

Now that he looked more closely, Pekkala realized they were not books at all but wooden boxes.

“Go on and open them,” said the Tsar.

Pekkala lifted up the first box, which was smaller than the one below. Opening it, he caught his first glimpse of the emblem which was to become his trademark in the years ahead.

“I have decided,” said the Tsar, “that the title of Special Investigator lacks…” He twisted his hand in the air, like the claw of a barnacle sweeping through an ocean current. “Lacks the gravitas of your position. There are other Special Investigators in my police force, but there has never been a position quite like yours before. It was my grandfather who created the Gendarmerie and my father who established the Okhrana. And you are my creation. You are unique, Pekkala, and so is that badge you will wear from now on. I noticed, as others have done, that certain silvery quality to your gaze. I have never known anything like it. One might think you suffered from a type of blindness.”
