Rachel pushed Margaret down the patio steps, but Thomas caught her before she fell.

We stood in silence long after his footsteps faded away. The woman—my mother-in-law, David’s real mother—leaned against the cold stone wall, trembling.

David turned to her. "Are you hurt?"

"He tightened it," she whispered. "Just enough to show me he means it."

David knelt and shone his light on the chain. It was heavy iron, bolted deep into the wall. No key hung nearby.

"He’ll come back," she said. "He always comes back. He likes to watch people choose."

"Choose what?" I asked.

"Between their lives and their secrets." She looked at David. "Your father faced the same choice. He chose Margaret. And Julian never forgave him."

David stood up slowly. He pulled the letter from his pocket and unfolded it. He shone his light on the bottom lines again.

*Look where the light never falls. Beneath the foundation. Behind the stone marked with a cross.*

"Beneath the mansion," David said. "There’s a cellar. An old root cellar Richard sealed off years ago. Margaret told me once he went down there every month. Said he was checking the foundation."

"He was hiding something," she said. "Richard told me. He said Julian would never find it. That it was buried behind a stone only he could identify." She looked at David. "He said you would know it. That it bore your initials."

David stiffened. "My initials?"

"He carved them himself. The day you were born."

David stared at the wall, thinking. Then he looked at his phone.

"Sunset in four hours. Julian expects an answer by then." He turned to me. "Rachel, can you get a message to Thomas?"

I checked my signal. One bar. Just enough.

"I can try."

"Tell him what we learned. Tell him Julian is the one. Tell him to watch Margaret. And tell him to get to the mansion. To the old cellar beneath the west wing. Before Julian realizes what we’re doing."

I typed fast, hit send. The message queued… then vanished.

"No luck," I said. "No connection."

David swore softly. He paced the small room, light swinging.

"Julian will be back by sunset. He expects us to agree. When we don’t… he’ll hurt Margaret. He’ll hurt her." He nodded toward his mother.

"Then we need to be gone before he returns," she said.

"There’s no way out," David said. "Door is locked. Windows are bricked. We’re trapped."

She looked up at the ceiling. Then at the far wall.

"Richard came down here once," she said quietly. "He told me this whole section was built over an old drainage tunnel. It was sealed decades ago. But he said… he said the seal was weak. And he showed me where the stones were loose."

She pointed to the far corner, behind the cot.

"There. Behind the loose stones. He said if I ever needed to escape… that was the way."

David rushed over. He pulled the cot aside. He ran his hands along the stonework.

"Here," he said. "They’re loose."

He began pulling stones out one by one. Dust filled the air. I helped him, clearing the debris. Minutes later, a narrow opening appeared. Cold air drifted through.

"It’s tight," David said. "But it goes somewhere."

He turned back to the woman. He knelt beside her.

"I can’t break the chain," he said. "Not without tools."

She touched his face. Her hand was gentle.

"Then you go. Both of you. Get to the mansion. Find what Richard hid. Expose Julian. And come back for me."

"I won’t leave you."

"You must." Her voice hardened. "You think I’ve waited twenty-five years to watch Julian destroy my son? Go. Save Margaret. Save the evidence. And then… come back and finish what Richard started."

David hesitated. He looked at the chain. At the tunnel. At me.

"She’s right," I said quietly. "If we stay, Julian kills all three of us. And he wins. If we go… we have a chance."

David took her hand. He pressed it to his chest.

"I will come back. I promise. Whatever happens. Whatever it costs."

"I know," she whispered. "You are my son. And you are stronger than Richard ever was."

David kissed her forehead. Then he stood. He shone his light into the tunnel.

"Rachel, first."

I crawled in. The passage was narrow, jagged, filled with dirt and cobwebs. David followed, pulling the stones back into place behind us. We crawled for what felt like miles—cold, damp, breathless—until finally, the tunnel opened into a drainage ditch half a mile from Blackwood Hall.

We stood up, gasping, covered in mud.

David looked back toward the house.

"She’s still there," he said. "Chained. Waiting."

"We’ll come back," I said. "But first… the evidence."
