Read Chapter 7: Cracking the Code

The first-class library on A-Deck smelled of leather and old paper, a sanctuary of quiet wealth that made Jack’s skin crawl in its civility. He’d chosen the far corner table, the one with a clear view of both entrances, and had arranged his stolen materials like a schoolboy preparing for an examination.

The silver locket lay open beside the red ledger. Its interior had been polished to a mirror shine, and etched into the backing plate was the code the veiled woman had carried: four lines of initials, numbers, and cabin designations that meant nothing to him at first glance.

He read them again, letting his finger trace the tiny engraving:

A.V.D. — 4127 — B-84 J.P.M. — 2286 — C-17 W.W. — 3913 — B-58 J.D.R. — 1744 — C-32

Four names. Four numbers. Four cabins.

Jack pulled the ship’s library copy of the *New York Social Register* from the shelf, a thick volume bound in burgundy morocco. He’d spotted it earlier, nestled between a Baedeker guide to America and a biography of Napoleon. First-class libraries on White Star liners were stocked with flattery for their wealthiest passengers, and nothing flattered a man more than seeing his name in print.

He opened the register to the B section first. B-84. Cabin numbers wouldn’t help him, but initials might. He scanned the pages, his eyes moving fast, when a name jumped out.

*Astor, John Jacob — 4127 Fifth Avenue.*

Jack’s breath caught. He flipped back to the locket. A.V.D. No, that wasn’t Astor. But the number—4127—that was an address. A Fifth Avenue address.

He stared at the four numbers again, his mind rearranging them.

4127. 2286. 3913. 1744.

What if they weren’t addresses at all? What if the digits were part of a different system? He thought of the banks he knew in New York—the grimy exchanges in the Bowery, the marble cathedrals of Wall Street—and how they filed their safe-deposit boxes. Numerals. Rows. Vaults with thousands of tiny steel doors, each waiting for a key.

The key in his pocket suddenly felt heavier.

He turned to the red ledger, flipping through the pages until he found the entry Andrews had logged before his death. The same notation appeared there, written in the steward’s cramped hand: *Item held. Deliver on proof of death.*

But below it, in a different ink, Andrews had scratched a single word: *Battery.*

Jack’s pulse quickened. Battery Park. The tip of Manhattan. Where the great banking houses kept their deepest vaults, the ones that never closed, never asked questions, and never turned away a man with the right key and the right number.

He pulled the locket closer, studying the numbers with new eyes. If the four digits weren’t addresses, perhaps they weren’t box numbers either. Not directly. Perhaps they were a cipher—an offset, a mathematical key to convert the cabin letters into something meaningful.

The cabin designations. B-84. C-17. B-58. C-32.

What if the numbers subtracted from something? What if they were a simple grid reference?

He took a blank sheet of ship’s stationery and began to work. The Titanic’s first-class cabins were arranged in a logical pattern: B-deck forward, C-deck aft. He converted the letters to numbers—A was 1, B was 2, C was 3—and began to calculate.

B-84 became 2-84. C-17 became 3-17.

He subtracted the box digits from the cabin numbers.

84 minus 41. 17 minus 22. 58 minus 39. 32 minus 17.

The results: 43, negative 5, 19, 15.

He swore under his breath. Nonsense. He was overcomplicating this.

Jack leaned back in the leather chair, rubbing his eyes. A steward passed and he ordered a whiskey to maintain appearances. The drink arrived in a crystal glass, and he swirled it absently, watching the amber liquid catch the electric light.

Think, Sparrow. You’re a thief. How would you hide a fortune?

Not with a code so complex you’d need a mathematician to crack it. Codes were for governments and spies. Professional criminals used something simpler. Something that looked innocent to anyone who didn’t know what they were seeing.

He looked at the four lines again.

A.V.D. — 4127 — B-84 J.P.M. — 2286 — C-17 W.W. — 3913 — B-58 J.D.R. — 1744 — C-32

Initials. Four sets. He knew those initials. Every New Yorker would. The Social Register had listed them all, and he’d been too dense to see it.

Astor. Vanderbilt. Morgan. Rockefeller.

No—not exactly. The initials didn’t match perfectly, but close enough to recognize the pattern. A.V.D. could be a cover name, an alias to mask the true owner. But the numbers, those were the real map.

He picked up the Social Register and turned to an appendix he’d noticed earlier: a listing of prominent New York families and their holdings. He found the banking section and scanned until he saw the name.

*The Knickerbocker Trust Company. Established 1884. Principal office at 4127 Fifth Avenue. Branch vaults throughout Manhattan.*

Number one: A.V.D. — 4127.

A bank address. Now the cabin letters made sense in an entirely different way. Each line might not be a separate box. Each line might be a separate account—a separate key and deposit location. The cabin designations could be a delivery instruction: books kept in a stateroom aboard the Titanic, packed for travel, meant to be claimed on arrival.

But two of the cabin letters were B-deck, two were C-deck. All first-class. All occupied by living passengers.

Unless they weren’t.

He flipped through the red ledger again, checking the entries Andrews had logged more carefully this time. The steward had recorded the contents of each delivery. Brass fittings for a clockmaker’s shop. Ship’s fittings for repairs. Silk bolts for a dressmaker.

Jack laughed out loud, drawing a sharp look from a dowager reading poetry across the room. He covered his mouth, but the revelation burned bright.

They weren’t shipping silk or brass or clock parts. They were shipping diamonds. Rough-cut, unregistered stones—the kind that could be slipped into a false-bottomed crate, moved through customs without a whisper, and sold on the black market for double their weight in gold.

The code was simple. Each line was a currency exchange: a specific Haight bank vault, a box number, and a claim ticket. The cabin letters weren’t descriptions of where the goods were hidden; they were the *delivery point* for each shipment.

B-84. He’d walked past that cabin on his way to dinner. B-84 was three doors down from Vance’s stateroom.

And C-17 was directly below, on the deck beneath.

Jack’s mind raced. Andrews had been the courier, moving shipments from the ship’s hold to these staterooms, logging each delivery in the red ledger. But Andrews hadn’t just been a deliveryman—he’d known the contents. He’d known what those polished crates carried. And someone had killed him for it.

The veiled woman was a collector. She passed the locket to Vance, who would pass it to his employer. The code was meant to be delivered in pieces, to prevent any single person from knowing the full map.

Now Jack held the entire thing.

He traced the last line again. J.D.R. — 1744 — C-32. John D. Rockefeller. If even half of what he suspected was true, the combined value of those vault contents was enough to buy his way out of every debt, every danger, every shadow he’d ever run from—and vanish into a life so comfortable that no enforcer or crime boss would ever find him.

But that meant he couldn’t sell the key. The key was worthless without the code, and the code pointed to vaults that required special access—clearances only the bank’s elite clients held.

Unless he found the lock the key actually opened.

He studied the key again, turning it over in his hand. Nothing on the surface indicated a bank name or a number. But he knew from London black markets that identical master keys existed for institutional vaults: grand banks that used a single master to access a nest of private boxes in the deepest chamber.

His hand tightened around the metal.

The door to the library opened, and Jack looked up sharply. A steward entered, scanning the room. When he spotted Jack, he walked over, shoulders set, face expressionless.

“Mr. Collins?”

Jack’s blood chilled. Not the name he’d given the purser.

“There’s a message for you,” the steward said, holding out a silver tray with a sealed envelope. “It was left at the purser’s desk by a gentleman who declined to give his name.”

Jack took the envelope, a habit born of caution. The seal was plain wax, pressed with a signet ring bearing a spade.

Inside, a single line of elegant handwriting: *You have the whole deck, but I hold the wild card. Dinner tomorrow, main dining room, table eight. I expect my chips returned—or we flip for something else entirely.*

No signature. No name. But Jack didn’t need one.

Vance had found him again, and whatever game he was playing, he’d just made clear that losing wasn’t an option.

Jack pocketed the note, looked out the library’s tall windows at the dark Atlantic beyond the glass, and began counting the hours until the ship would meet its end.
