“Ah, yes,” Mr. Gray said, moving to Vladimir’s side. “That is simply an illusion. Come, look closely.”
Vladimir squatted to the floor and examined the marble. A thin, fine seam had been cut along the border of the central stone. “It is practically invisible,” Vladimir said.
“Step away,” Mr. Gray said. Positioning himself over the stone, he applied pressure to its center. The stone lifted from the floor as if on springs. With a twist of his hand, Mr. Gray removed the central stone of the labyrinth.
“Amazing,” Saitou-san said, watching over his shoulder.
“There is nothing a fine stonemason and an abundance of funds cannot achieve,” Mr. Gray said. “You were acquainted with the late Mrs. Rockefeller?”
“No,” Vladimir said. “Not personally.”
“Ah, well, a pity,” Mr. Gray said. “She had a keen sense of social justice marked with the folly of a poetic nature-a combination quite rare in women of her stature. Originally she designated that when angelologists arrived to claim the object under my care, I was to lead whoever came here to the labyrinth and ask for a series of numbers. Mrs. Rockefeller assured me that whoever came would know these numbers. I have them memorized, of course.”
“Numbers?” Vladimir said, baffled by this unexpected test.
“Numbers, sir.” Mr. Gray gestured to the center of the labyrinth. Below the stone there was a safe, a combination lock at its center. “You will need numbers to open this. I suppose you might think of yourself as the Minotaur making your way into the stone labyrinth.” He smiled, enjoying the bafflement he had caused.
Vladimir stared at the safe, its door perfectly flush with the floor beneath the labyrinth as Saitou-san bent over it. Saitou-san said, “How many numbers in each combination?”
“That, I cannot tell you,” Mr. Gray said.
Saitou-san turned each of the dials in succession. “Abigail Rockefeller’s cards were made specifically for Innocenta to decode,” she said, speaking slowly, as if searching her thoughts. “Innocenta’s responses affirmed that she had counted the lyre strings on the cards and had-I assume-written down the numbers.”
“The sequence,” Vladimir said, “was twenty-eight, thirty, thirty-eight, and thirty-nine.”
Saitou-san turned each of the four dials to correspond with the numbers and pulled at the safe. It didn’t open.
“This is the only sequence of numbers we have,” Saitou-san said. “They must work in some combination.”
“Four numbers and four dials,” Vladimir said. “That makes twenty-four different possible combinations. There is no way we can try all of them. There isn’t time.”
“Unless,” Saitou-san said, “there was a designated order to the numbers. Do you remember the chronology in which they were given? Verlaine told us the sequence in which numbers appeared on the cards.”
Vladimir thought for a moment. “Twenty-eight, thirty-eight, thirty, and finally thirty-nine.”
Saitou-san moved each dial, aligning the numbers carefully. Wrapping her finger around a metal lever, she pulled the handle of the safe. It lifted without resistance, exhaling a soft gush of air. Reaching into the cavity, she withdrew a heavy bundle of green velvet and unwrapped it. The sound chest of the lyre threw waves of golden illumination over the stone labyrinth.
“It is lovely,” Saitou-san said, turning it to examine it from all angles. The base was round. Two identical arms bowed out and then curled, like the horns of a bull. The golden surfaces were smooth and polished to a gleam. “But there are no strings.”
“Nor is there a yoke,” Vladimir said. He knelt by Saitou-san’s side and looked at the instrument cradled in her hands. “It is just one piece of the lyre. A most important piece, but alone it is useless. This must be why we were sent to four locations. The pieces have been scattered.”
“We need to tell the others,” Saitou-san said, carefully returning the lyre’s body to the velvet bag. “They need to know what they are looking for.”
Vladimir turned and faced Mr. Gray, who stood trembling between them. “You didn’t know the combination. You’ve been waiting for us to come and give it to you. If you had known, you would have taken it yourself.”
“There is no need to worry about what I know or do not know,” Mr. Gray said, his face growing red from perspiration. “The treasure belongs to neither of us.”
“What do you mean?” Saitou-san asked, incredulous.
“His meaning,” said a voice at the far end of the apse, a familiar voice that sent chills of terror through Vladimir, “is that the game has been over for many years. It is a game that the angelologists have lost”
In his fright Mr. Gray’s monocle fell from his eye, and without a moment of hesitation, he scurried from the apse and into a side aisle of the nave, the fabric of his gray suit appearing and disappearing as he traversed puddles of light and shadow. Watching Mr. Gray flee, Vladimir made out bands of Gibborish creatures along the aisles of the church, their white hair and red wings visible in the dull light. The creatures turned to watch as Mr. Gray passed, avid as sunflowers to the movement of the sun. Before he could escape, however, a Gibborim seized Mr. Gray. As Vladimir watched, all doubt cleared about the nature of the meeting: The angelologists had fallen into a trap. Percival Grigori had been waiting for them.
The last time Vladimir had met Grigori was many decades before, when Vladimir was a young protégé of Raphael Valko. He had seen firsthand the atrocities the Grigori family had perpetrated during the war. He had also witnessed the great pain they’d inflicted upon angelologists-Seraphina Valko had lost her life because of Percival Grigori’s machinations, and Gabriella had come close to dying as well. Back then Percival Grigori had cut a startling, fearsome figure. Now he was a sickly mutant.
Grigori gestured and the Gibborim brought Mr. Gray forward.
Without warning, Grigori cracked the ivory head of his cane from the shaft, twisting the steel blade of a dagger from its mooring. For a second the knife glinted in the weak light. Then, in one swift movement, Grigori stepped forward and plunged the dagger into Mr. Gray’s body. Gray’s expression changed from surprise to disbelief and then to wilting, disconsolate anguish. As Percival Grigori withdrew the knife, Mr. Gray collapsed to the floor, whimpering softly, blood collecting about him. In a matter of moments, his eyes held the watery gaze of death. As swiftly as he’d unsheathed the knife, Percival wiped it clean on a white square of silk and inserted it back into the shaft of the cane.
Vladimir saw that Saitou-san had edged away from him with the sound chest in hand, slinking silently toward the rear of the church. By the time Percival noticed, she was within reach of the door. Percival lifted his hand and ordered the Gibborim after her. Half of the creatures turned upon her, while the remaining Gibborim stepped forward, the hems of their robes brushing against the floor as they surrounded the apse. With a second gesture, Percival instructed these creatures to take hold of Vladimir.
Clutched tightly in their grasp, Vladimir inhaled the scent of the creatures’ skin; he felt the chill of their bodies behind him. A cool gust of air swept the nape of his neck as the creatures beat their wings, steadily, rhythmically.
“She will take the lyre to Gabriella!” Vladimir cried, struggling against the hold of the creatures.
Percival looked upon Vladimir with contempt. “I was hoping to see my dear Gabriella. I know that she is behind this little recovery mission. She has become quite elusive over the years.”
Vladimir closed his eyes. He recalled that Gabriella’s infiltration into the Grigori family had been a sensation in the angelological community, the largest, most influential undercover job of the 1940s. Indeed, her work had paved the way for modern surveillance of the Nephilistic families and brought them useful information. But it had created a dangerous legacy for all of them. After so many years, Percival Grigori still wanted revenge.
