Read Chapter 18: The Letter

Abigail’s hands trembled as she broke the wax seal, the crack of it sharp as a pistol shot in the silent wheelhouse. The paper inside was yellowed, brittle as dead skin, and the ink had faded to a sepia brown, but every word was still legible.

Rosa leaned over her shoulder, and Mack stepped closer, the deck tilting beneath him. The ship was still moving under a wind that shouldn’t have been pushing them—not northeast, not against the storm’s will. But he pushed that thought down. The letter was the key. Everything pointed to it.

Abigail read aloud, her voice low and careful, as if the words might shatter if spoken too loud.

*“To Captain Elias Blackwood, master of the Santa Catalina, by the authority of the Royal Admiralty and in the service of His Majesty King George—*

*I write to you not as your admiral, but as a man who owes you a debt he can never repay. The charges leveled against you by Commodore St. John are false, born of jealousy and corruption. Your capture of the French prize ship Revenant, and your delivery of her coded dispatches, revealed a conspiracy that would have cost England her Caribbean holdings. You acted not as a pirate, but as a privateer under my commission, and I have the papers to prove it.*

*Your name will be cleared. Your crew will be pardoned. Your family will inherit your honor, not your shame.*

*Deliver this letter to me in person at Myrrdin’s Island, and I will see it done. The island does not appear on any chart, but you know the way—where the sun sets and the sea boils, there you will find me waiting.*

*Your friend, Admiral John Pimm, 3rd of March, 1711.”*

Abigail looked up. The wind howled past the wheelhouse windows, rattling the glass. “Myrrdin’s Island,” she said. “That’s where we’re going. Where Blackwood was going the night he died.”

Mack’s throat was dry. He’d felt it building for hours—that cold pressure behind his eyes, that whisper at the edge of his hearing, like a man speaking just out of sight. He gripped the edge of the chart table, knuckles white, and forced the words out.

“Pimm promised to clear his name. Blackwood was trying to deliver this letter. He never made it. The Santa Catalina sank with the proof in her hold.” Mack stared at the paper. “So the curse isn’t about gold. It’s about this.”

Rosa shook her head slowly. “But that was over two hundred years ago, Mack. Pimm is dead. Everyone is dead. How can Blackwood complete his voyage if the man he needs to deliver it to doesn’t exist?”

The question hung in the air like smoke. Mack didn’t have an answer. He looked at the letter again, at the date—1711—and something cold settled in his chest.

“Pimm wrote that the island doesn’t appear on any chart,” Mack said. “And Blackwood knew the way. That means there are charts, just not ours. Thorne said Blackwood’s ghost is in the gold. If we’re sailing where the sea boils… maybe we’re sailing where Pimm still is.”

Abigail’s face went pale. “You’re saying we’re going to meet a dead admiral.”

Mack didn’t answer. The wheelhouse door banged open, and a cold gust of spray hit them. The kid—Danny—stood there, rain streaming down his face, his eyes wide.

He pointed aft. “Captain, you need to see this.”

Mack followed him out onto the deck. The storm they’d been chasing had turned strange. The squall line ahead wasn’t just dark clouds—it was *wrong*, shaped like a wall that stretched from the water to the heavens, black and bruised purple at the edges, swollen with something besides rain. The sea beneath it didn’t roll in waves like the Atlantic should. It churned. Bubbles the size of dinner plates broke the surface, and the water itself seemed to be steaming, wisps of vapor rising off the swells.

“That’s not a storm,” Rosa said, coming up beside him. She pointed at the water. “Look at the color. That’s not open ocean. That can’t be open ocean.”

Mack looked down. The Sea Serpent had crossed into water that was green and milky, streaked with pale sediment. The depth gauge in the wheelhouse had gone blank two hours ago—another thing he couldn’t explain, another thing that shouldn’t have been possible. But now he saw what the boiling sea meant.

Islands. Shallows. And not on any chart.

The letter’s final words burned in his mind: *where the sun sets and the sea boils, there you will find me.*

He turned to look at the horizon behind them. The sun was setting, a red ball bleeding into the ocean. Ahead, the boiling sea churned and hissed. And in the middle of it, barely visible through the steam, was a dark shape—not a rock, not a reef, but something too regular, too straight-edged to be natural. A masted silhouette.

A ship.

Abigail’s breath caught. “Is that the Santa Catalina?”

Mack’s hand went to the knife at his belt—Blackwood’s blade, the one that had found him in the wreck. It was warm to the touch, hotter than it should have been. And as he stared at the ship through the rain and steam, he felt the voice again, stronger than ever, not just at the edge of his hearing but inside his skull.

*Bring her home.*

He tried to pull the knife away, but his fingers wouldn’t uncurl. The voice was his own now, and it wasn’t asking.

“Mack?” Rosa’s voice was sharp, scared. “Mack, you’re bleeding.”

He looked down. His nose was bleeding. He hadn’t felt it. A thin stream of red ran onto his lip, dripped onto the deck, and the wind carried it specks of it out to the churning sea.

“I’m fine,” he said, and even he didn’t believe it.

But his eyes couldn’t leave the shape in the water. The Santa Catalina didn’t look like a wreck. She looked whole—real and solid as the day she was built—and she was moving, swinging broadside, coming toward them. The sails were furled on her yardarms, but she cut through the boiling water without effort, as if the sea was moving her, not the wind.

Abigail grabbed his arm. “Mack, we need to turn around. That’s not a ship. That’s a ghost.”

For a moment, Mack thought she was right. Every instinct told him to turn the wheel and put the Sea Serpent’s stern to that impossible shape and run for open water, back to the world of charts and radar and rules that made sense. But his hand wasn’t reaching for the wheel. His legs were walking forward, toward the bow.

“Mack!” Rosa shouted.

He stopped at the rail. The boiling sea had gone suddenly, eerily calm, the water glassy and discolored, the steam rising thick around them. And in the mist, the Santa Catalina was there, close now, close enough that he could see the figures on her deck—men in seaman’s rags, standing frozen at their stations, faces grey and empty, watching him.

His own crew was shouting now, pointing at the ghost ship. The Sea Serpent’s engines coughed, sputtered, died.

Mack felt the letter in his hand. He didn’t remember taking it from Abigail. He looked down at it, at Pimm’s faded promise to clear Blackwood’s name, and he understood what the compass in the wheelhouse had been trying to tell him, what Thorne had meant by the crew waiting below the keel, what the gold had been screaming for two hundred years.

The voyage wasn’t about delivering the letter to create an ending. It was about delivering it so Blackwood could let go of the beginning. The curse wasn’t greed. It was unfinished business.

And Pimm wasn’t waiting on the island. He was waiting on the ship.

The ghost of a man in a worn captain’s coat stood at the Santa Catalina’s bow, watching him. His face was shadowed, but Mack saw the shape of it under the tricorn hat—the same face he’d seen in the mirror, the same face that had been growing in his reflection since the day he pulled the knife from the wreck.

Blackwood’s lips moved. Mack heard the words clear as a bell.

*You look good in my coat.*

Mack reached up and touched his shoulders. He hadn’t put on a coat. But he was wearing one. Cold, salt-stained wool. He hadn’t felt it until he looked.

Rosa screamed his name.

Mack stepped toward the rail. The ghost ship’s boarding plank slid out toward him, and he didn’t remember choosing to reach for it. His hand closed on the rope, and the voice inside him whispered, quiet as a prayer.

*Finish what I started.*

He looked back at Rosa. Her face was white. Her mouth was open, but the words were lost in the howl of wind that had returned.

“Hold the letter,” he said.

She shook her head. “No. You come back here.”

“Hold the letter,” he repeated, and he saw something in his own hand change. The letter was burning, but it wasn’t consumed. The edges were smoking, curling black, and Pimm’s words were rising off the paper like clouds, vanishing into the boiling sky.

He boarded the ghost ship. The plank did not move beneath him. The dead crew did not turn to look.

Behind the helm, waiting near the wheel, was Admiral Pimm, in the uniform of the Royal Navy, a bullet hole over his heart and two hundred years of patience in his eyes.

“You’re late, Captain,” Pimm said. “Seal the deal.”
