The Vow Beneath the Thames
Read Chapter 10: Eleanor's Trail
Finch’s office was a glass box on the eighteenth floor of a Canary Wharf tower, all pale wood and abstract art that cost more than Adam’s flat. The receptionist—a sharp-featured woman with a smile that didn’t reach her eyes—told him Ms. Finch had left early.
“Left where?”
“I’m not at liberty to—”
Adam placed his card on the desk. “Detective consultant. Urgent matter regarding a client of hers. Marcus Pendergast.”
The name landed. The receptionist’s fingers hovered over the keyboard. “She… she didn’t say. She took her bag. Said she had a dinner.”
“With who?”
“I don’t know.” A flicker of genuine unease crossed her face. “But she’s been different lately. Jumpy. She cancelled all her meetings for tomorrow. That’s not like her.”
Jumpy. Cancelled tomorrow. Tomorrow night was the ceremony. The window Eleanor herself had warned him about.
Adam was already moving toward the elevator. He pulled out his phone and rang Sarah.
“Adam? What’s wrong?”
“Finch is gone. Her office says she left early. I need her address.”
A pause. “I have it. She gave it to me when we exchanged notes. But Adam—if the Covenant knows she’s been talking to you, they’ll move her. They won’t wait for the ceremony.”
“Then I’m not going to wait either.”
The address was a converted warehouse in Shad Thames, a block of exposed brick and black iron balconies that looked out over the river. Adam killed the engine of his car two streets early and went on foot. Old habit. He wanted to see who was watching before they saw him.
He counted three. A man in a grey work jacket leaning against a lamppost, pretending to scroll his phone. A woman in a delivery driver’s uniform, sitting in a van with the engine idling, loitering in a no-loading zone. And a kid on a bike, too old to be playing in the street, moving in slow loops around the block.
The Covenant’s watchers were lazy. Or they didn’t care if they were seen.
Adam slipped through a service alley behind Finch’s building, found the fire escape, and climbed. Her window was on the third floor, a wide casement that gave onto the iron landing. It was locked.
He took out the leatherman he’d carried since his Met days, worked the latch. Three seconds. He was inside before the delivery van’s engine had stopped idling.
The apartment was neat. Minimalist. A lawyer’s flat, tidy and functional—but wrong. The details clawed at him. A half-drunk cup of coffee on the kitchen counter, still warm when he touched the ceramic. A coat left on the back of a chair. A phone charger snaked across the floor, cable still plugged into the wall, no phone in sight.
She hadn’t left for a dinner. She’d been taken, or she’d run—and either way, she’d left in a hurry.
Adam moved through the rooms. The bedroom was undisturbed. The bathroom the same. He was about to head back to the kitchen, look for signs of forced entry, when he caught it: the corner of something sticking out from under the living room rug, just by the sofa. He lifted it.
A map of London. But not the kind you bought at a newsagent.
It was printed on heavy archival paper, the kind used for museums and restoration work. The street grid was faded, a ghost of a city that had been drawn before the Victorian sewers and the tube lines came to reshape everything. But layered over that old skeleton were marks in fresh red ink: a web of lines and nodes tracing beneath the streets, connecting the church crypt in Bermondsey to the Wapping basin, to a knot of tunnels under the Bank of England, then spreading outward like veins across the whole financial district.
Underground tunnels. Not the Tube. Not the sewers. Something else.
Adam traced the line from the crypt to Wapping, then followed it northwest. It ended at a cluster of symbols he didn’t recognize—spidery marks like the ones on the parchment fragment he’d taken from the crypt. He couldn’t read them, but he didn’t need to. The pattern was unmistakable. The ceremony chamber where the ritual would happen wasn’t just any chamber. It was the hub. The centre of the web.
And the map had been annotated in a hand that wasn’t Finch’s—or not only hers. Circle around Shad Thames. A note in the margin, cramped and hurried: they’re coming. Another, near the Wapping node: the fifth anchor is me.
Eleanor knew she was the fifth. The next victim. And she’d known it long before she’d warned Adam about the ceremony.
He pulled out his phone, snapped a photo of the map, then folded it and tucked it inside his jacket. He was stepping toward the window when he saw it—a slip of paper on the floor beside the sofa, half-hidden where the rug had been displaced. He bent and picked it up.
It was a receipt. From a shop in Bermondsey. The watch shop. The Silent Broker’s front.
Finch had been there. Recently.
The air in the room went cold. Adam thought of the Broker’s agent, the smile that didn’t reach his eyes when he’d warned Adam that Sarah’s payment was nearly clear. Eleanor Finch had been a Covenant anchor once. Left behind after a failed ceremony. She knew too much. And now, according to that map, she was the next one on the table.
But she wasn’t missing yet. Not taken. She’d gone to the Broker first. She’d known she was marked, and she’d gone to the one institution in London that traded in open debts—maybe looking for protection, credit, time. Or maybe she’d gone to negotiate a different kind of service.
Adam’s ring pulsed hot against his knuckle. He looked down at it. The band had always sat loose, comfortable, an ornament he’d picked up second-hand years ago. Now it felt tight. He’d thought it was a clue. Eleanor had marked it as collateral.
A fifth anchor. The fifth ring.
He pulled out his phone and called Sarah.
“Tell me everything Finch told you about the Covenant,” he said, voice low. “Every word. I think she was planning on giving them something she didn’t intend to survive.”
Sarah’s breath hitched. “Adam, she told me her story—she was left behind because she wasn’t a perfect fit. Her vow was fulfilled, but incompletely. They released her because keeping her cost more than binding her. She said she thought she was out.”
“But she knew they kept files. Debts. The Broker runs on debts.”
Quiet. Then: “Her brother. She mentioned a brother, once. Adam—if the Covenant or the Broker holds something over her family, they’re not just taking her for the ritual. They’re asking her to go willing.”
That was the pattern. Marcus Pendergast went willing. All of them did. The Covenant didn’t take victims; they made them walk into that chamber themselves, bound by vows they couldn’t break.
Eleanor had known she was next. And she’d gone out to meet them anyway.
Adam looked at the map. The web of tunnels beneath London spread like a wound. He’d assumed the ceremony site was at Wapping. But the hub—the centre of the red lines—was somewhere else entirely. Beneath the Bank. Beneath the square mile where the city’s oldest promises had been made with blood and iron.
He pocketed the receipt and climbed out through the window, dropping down the fire escape as the kid on the bike rounded the corner and spotted him. The kid’s hand went to his collar—a mic, cheap.
Adam ran.
Behind him, the delivery van’s engine revved. The watchers were closing in. The Covenant knew he’d been here. They knew he had the map now. And they didn’t need the element of surprise anymore.
The ceremony was tomorrow night.
Eleanor Finch was already inside the web.
And Adam was wearing the ring that would make him the one to take her place if she didn’t show.
