My sister walked into my wedding wearing a white bridal dress

The standoff hung by a thread thinner than gossamer. The storm had reached its crescendo; lightning fractured the night sky, turning the gothic facade of Saint Jude’s into a grotesque silhouette of bone and ash.

"Don't do it, Lila!" Mia barked, moving to flank the vehicle, her bridal gown soaked and heavy. "She’ll shoot him the second you turn that lock!"

"Shut up, Mia," Celeste snapped, her eyes never leaving me. "You spent two years playing the crazy sister, pretending to be Victoria’s obedient doll. Did you really think she trusted you? She left the true inheritance to me. The Vance legacy, combined with every penny Nicholas Sterling bled from this town."

I pulled the heavy brass key from my coat pocket. It felt burning hot against my frozen palm.

"Arthur has been like a father to us," I said, my voice remarkably steady despite the terror threatening to crush my ribcage. "He served our parents faithfully. He doesn't belong in your war, Celeste."

"None of us belong in this war, little sister," Celeste replied mockingly. "Yet here we are, dressed for a wedding and drenched in blood. The key, Lila. Walk to the chapel doors and unlock the grate beneath the altar. If Owen twitches a muscle, Arthur dies."

Owen’s gaze met mine. In the darkness, behind the steady focus of his eyes, was an unspoken message. We had survived Mia’s madness; we had survived Victoria’s courtrooms. We were not going to lose our lives tonight.

"I’ll do it," I said. "Let Arthur lie on the grass. Step away from him."

Celeste shoved Arthur’s limp body off the hood. He tumbled onto the wet clover with a dull thud, breathing shallowly but alive. Celeste stepped backward, keeping her weapon trained on Owen while signaling me toward the arched sanctuary doors.

I walked up the stone steps, passing the bodies of the mercenaries Mia had neutralized. Mia fell into step behind me, her gun held low, her breathing shallow and ragged. For the first time in our lives, the twin sisters were moving in absolute unison.

We stepped into the nave of the ancient chapel.

The interior smelled of damp stone, ancient wax, and decay. Cobwebs hung like tattered shrouds from the vaulted rafters. At the far end of the central aisle stood the high stone altar of Saint Jude, carved from solid grey granite.

Behind us, Celeste followed at a measured distance of ten paces, her gun tracking the back of my head. Owen followed behind her, gun raised, waiting for the slightest opening.

"Beneath the central plinth," Celeste commanded, her voice bouncing off the vaulted ceiling. "There is an iron vent. Turn the key ninety degrees clockwise."

I knelt before the altar, the cold stone biting through my jeans. Beneath the heavy fabric of the altar cloth, hidden in the shadow of the carved stone relief, was a brass escutcheon plate, aged green with verdigris.

I slid the key into the lock. It seated with a heavy, satisfying click.

"Turn it," Celeste whispered, stepping closer, the greed burning brightly in her green eyes. "Turn it now, Lila!"

I placed my fingers on the key. But instead of turning it clockwise, I remembered the water-stained photograph in my pocket. The photograph of the three cradles. On the back, written in my mother’s faded, elegant cursive, had been a single sentence: *Truth is found only in reverse.*

I turned the key counterclockwise.

A deep, mechanical groan reverberated beneath the stone floor. But the altar didn't open. Instead, a heavy iron portcullis—a medieval security gate installed by our paranoid grandfather—dropped from the vaulted arch above with the deafening crash of a guillotine.
