My brother poured champagne over my head in front of 200 wedding guests because I refused to give him Grandpa's beach house, but a lawyer at table four had other plans...

The house was completely still as midnight approached.

Outside, the tide was coming in, the Atlantic roaring against the cliffs with rhythmic, thunderous power. The floorboards groaned gently under my feet as I walked through the kitchen toward the basement door.

I held a high-powered tactical flashlight in one hand and the heavy iron key in the other.

The basement smelled of earth, damp stone, and old cedar shavings. At the far end of the cellar, half-buried behind stacks of seasoned firewood and lobster traps, was a low archway made of hand-cut granite blocks.

I cleared the debris away, coughing as decades of dust rose into the air.

Behind the woodpile was a thick, iron-reinforced oak door, covered in green sea moss and heavy iron bolts. In the center was an ornate, antique keyhole shaped like an inverted anchor.

My heart began to hammer against my ribs.

*Arthur had maintained the navigation beacon to protect the property,* I thought. *He gave me the land patent to keep Sterling out. But why the warning? Why tell Vance that some doors were locked for a reason?*

I slid the iron key into the slot.

It resisted for a second, stiff with rust, before turning with a heavy, metallic *CLACK* that reverberated through the stone floor beneath my boots.

I pulled the door open.

A rush of cold, damp air blasted into my face—an air that smelled of ozone, deep seawater, and something else... something ancient and metallic, like old copper and burnt sulfur.

A flight of rough-hewn stone steps led down into the blackness, descending far below the foundation level, down toward the sea line where the waves pounded against the cliff face.

I switched on the flashlight, the bright white beam cutting through the darkness.

Step by step, I went down.

The air grew colder. The sound of the ocean became deafening, vibrating through the granite walls around me. At the bottom of the stairs was a long, narrow tunnel carved out of the natural rock, leading toward the sound of the surf.

At the end of the tunnel was a second barrier—not a wooden door, but a massive steel safe door from the early 1900s, like something from a bank vault.

I approached it slowly, the beam of my light sweeping across the rusted dial and the heavy iron handle.

Then I froze.

The dial hadn't been turned. The safe wasn't locked.

Lying on the damp stone floor in front of the door was a fresh, unburned cigarette butt, stamped with a golden logo I had seen only once before: the private crest of Richard Sterling’s personal luxury brand.

And right beside the cigarette butt was a trail of wet, dripping saltwater footprints leading *out* from behind the heavy steel vault door, heading deeper into the shadows of the cave.

Before I could turn, before I could breathe, the sound of metal scraping against stone echoed from the darkness behind me.
