Read Chapter 6: The Abbey of Numbers

The night train had spat them out at Lewes before dawn, and by the time the sun burned the mist off the South Downs, Marcus Webb was already regretting the last cup of station coffee. It sat sour in his stomach as he and Sophie picked their way through waist-high nettles toward the broken shell of Whitmore Abbey.

“You’re sure this is it?” Sophie asked, ducking under a fallen lintel. Her voice echoed off stone that hadn’t heard speech in centuries.

Marcus pulled the postcard from his jacket. The symbol Tom had scrawled—a circle quartered by a cross, each quadrant holding a crude numeral—matched the one from the Lyon folder. Sophie had plotted it against old Cistercian land grants. Whitmore. He’d hoped Tom was wrong. Hoped the whole trail would dead-end here and he could pretend his brother had just… drifted, like the police said.

“The coordinates are exact,” he said, folding the card away. “Tom didn’t make mistakes.”

The abbey’s nave was open to the sky, roof beams long since rotted or scavenged. But Marcus wasn’t looking at the nave. He was counting flagstones from the north transept, matching a diagram Sophie had sketched on the train. Nine paces. Turn. Seven paces. At the tenth stone, he stopped.

“Here.”

The stone looked identical to its neighbours—grey, pitted, indifferent. Sophie knelt and ran her fingers along its edge. “There’s a groove.” She produced a small pry bar from her bag. The stone lifted with a groan of reluctant earth.

Beneath it, a narrow stair spiralled into blackness.

Sophie clicked on her torch. The beam cut a white wedge into the dark, revealing walls slick with moisture. Marcus followed her down, the air growing colder and heavier with every step. The stairs ended in a low vaulted crypt. And there, in the centre, they stopped.

Columns. Twelve of them, arranged in a circle, each carved with dense bands of script and numerals. Not Latin. Not French. Something older—a merchant’s tally, figures and abbreviations that looked like the bastard child of Arabic numerals and Lombardic script.

“Christ,” Marcus breathed.

Sophie was already circling the nearest column, torch tracing the carvings. “This is a ledger. A physical, stone-cut ledger.” She tapped a sequence near the base. “Look—‘Bardi, 1312. Wool, 400 sacks. Gold, 12 marks.’ They’re recording transactions.”

“The Bardi were bankers,” Marcus said. “Florentines. They bankrolled kings.”

“They bankrolled *everything*.” Sophie moved to the next column. “But this isn’t banking. It’s a map. Each column lists a fortress, a treasury location, and a cipher.” She paused at the seventh column, her torch trembling. “Marcus. Look at this one.”

He joined her. The carving was deeper here, the letters sharper. It read: *FERRO BANCO. SOTTO LE ALPI. LA STRADA CHIUSA.*

“Iron bank,” Marcus translated. “Under the Alps. The locked road.”

“The guardians of the locked road,” Sophie echoed. “The same phrase as on the coin. So the company that took the Lyon folder—they’re not just chasing reliquaries. They’re tracing the Bardi’s collateral vaults. And this one’s in the Italian Alps.”

She crouched and examined the base of the column. “There’s a date. 1319. And a seal.” She brushed away centuries of grime. “A wolf. Same as the coin.”

Marcus knelt beside her. “So the wolf is the Bardi mark?”

“Or the guardians’ mark. The people who *hid* the vaults.” Sophie’s voice dropped. “The Lyon folder had a partial cipher key. And you have Tom’s postcard with that symbol. The pieces are fitting together.”

Something scraped above them. Loose stone, skittering down the stairwell.

Marcus went rigid. Sophie killed her torch. Darkness swallowed them whole.

Footsteps. Multiple sets, moving with practiced efficiency. A voice, female, with a clipped Eastern European accent: “The nave is clear. Check the transept for a false stone.”

Sophie’s hand found Marcus’s arm in the dark. Her grip was iron. “They know the entrance protocol,” she whispered. “They have the Lyon folder.”

Marcus’s mind raced. The columns. The steps. The single stairwell. They were trapped in a stone box with one exit. He felt along the nearest column’s base, fingers finding seams, carvings, nothing useful—

A beam of light stabbed down the stairs. “Two sets of footprints,” the same voice called up. “They’re here. Seal the entrance.”

“No,” Marcus breathed. He looked around desperately. The crypt was circular, the columns arranged around a central dais. On the dais, a flat stone slab bore deeper carvings—a wolf’s head, jaws open, and beneath it a series of numbers. 7. 3. 9. 1.

He remembered the columns. The seventh was marked with a different numeral sequence. The third had a wolf’s paw chiselled at its base. He looked at the slab again. *7-3-9-1.* A sequence. Column seven, column three, column nine—

“Sophie. The columns are keyed to the slab. It’s a combination.”

She was already moving. She pushed the seventh column’s base—nothing. She tried twisting. Still nothing. Marcus joined her, fingers finding a slight give in a carved wolf’s eye. He pressed. A deep grinding sound echoed from somewhere below the floor.

Column nine. Then eleven. Then—

A section of the dais slid sideways, revealing a narrow shaft with iron rungs descending into further dark.

But the footsteps were closer now. The female voice rang out, sharp: “We have you cornered. Come out and we’ll discuss terms. Stay, and we’ll burn the abbey to its foundations.”

Marcus looked at Sophie. She was already at the shaft’s edge, torch aimed down. “It’s deep. But there’s a floor. Maybe another chamber.” She looked back at him, and in the faint light he saw the calculation in her eyes. “We don’t have a choice.”

He didn’t argue. He climbed onto the rungs, Sophie following, and they descended into the earth as the sound of boots thundered down the stairwell above. Ten feet down. Twenty. The shaft opened into a rough-hewn tunnel running north.

Behind them, a shout. A curse. Then a sharp crack—a gunshot, echoing off ancient stone.

“They’re shooting,” Sophie said, her voice tight.

“They’re not aiming,” Marcus replied. “They’re trying to scare us into stopping.”

It worked. His hands were slick with sweat on the iron rungs. The tunnel floor was uneven, cracked, and after fifty yards it ended in a collapsed wall of rubble. But tucked into a niche beside the rubble was a small iron chest, no larger than a shoebox, banded with rust.

Sophie reached it first. She worked the latch—it gave with a scream of corroded metal—and inside, wrapped in oiled cloth, lay a rectangular plate of brass. It was engraved with a dense grid of numbers and letters. And at the top, in clear Latin: *AMORE ET LABORE. THE LEDGER OF BONES.*

Marcus took it. The plate was heavier than it looked.

Behind them, the sound of boots grew louder. They were coming down the shaft.

“The rubble,” Sophie said. “Can you move it?”

Marcus wedged his shoulder against the largest stone. It gave an inch. Another. Sophie added her weight, and together they shoved a gap wide enough to slip through. Beyond it, another tunnel—fresher air, a hint of daylight.

They crawled through, scraping elbows and knees, and emerged into a shallow chalk pit overgrown with brambles. The abbey loomed above them, half a mile uphill.

Sophie pulled a bramble from her hair, gasping. “They’re still in the crypt. They’ll find the shaft.”

“Then we move.” Marcus pocketed the brass plate. “And we don’t stop until we’re out of this county.”

But as they scrambled up the slope toward the road, his phone buzzed. A single message, from an unknown number.

*They took the Lyon folder because it contained your brother’s name. Come to Turin if you want to know why he vanished.*

Marcus stared at the screen. The sender’s timing was perfect—again. Whoever was watching him knew exactly where he was.

Sophie saw his expression. “What is it?”

For a heartbeat, he considered lying. Then he handed her the phone.

“Tom isn’t just missing,” he said. “He was a target.”
