Rain lashed the windows of the crumbling estate, thunder rumbling like a distant accusation. Theo gripped the flashlight, its beam slicing through attic gloom thick with mildew and regret. He'd come here after the lawyer's call—inheritance from an uncle he barely remembered. The trunk sat in the corner, iron bands rusted, lid ajar as if waiting.

He knelt, wood splintering under his knees, and flipped it open. Amid moth-eaten clothes, the diary tumbled free. Leather cover cracked, embossed with Theo's initials—impossible, since Uncle Elias had died childless. Heart thudding, he cracked the pages. Ink blurred but legible: 'The boy isn't gone. I hid him where the roots twist deepest.'

A chill draft snaked up his spine, carrying the sour tang of damp earth. Theo's breath fogged the air. Pages deeper in: sketches of a face—his own, but younger, eyes hollowed by shadows. 'He came back last night,' one entry read. 'Whispered my sins through the floorboards.' Elias's sins? Theo had heard rumors—disappearances in the family line, whispers of a bastard son walled up alive. Folklore, he'd thought.

Footsteps echoed below—slow, deliberate on the stairs. Theo froze, beam trembling. No one else was in the house. The attic door creaked open on its own, hinges screeching like a plea. He bolted it shut, pulse hammering, and pored faster. 'The secret binds blood,' Elias wrote. 'To free it is to become it.' A photo slipped out: Theo's mother, young and terrified, cradling an infant that wasn't him.

Shadows lengthened as storm clouds choked the moon. Something scratched beneath the floor—faint at first, then rhythmic, like nails carving bone. Theo pressed his ear down, floor cold as grave soil. The scratching spelled letters: T-H-E-O. His name. Sweat beaded on his lip, tasting salt and fear. The diary's last page, unfinished: 'He's here now, smiling—'

The beam flickered out. In the pitch black, a breath warmed his neck, carrying words like rustling leaves: 'Welcome home, brother.' The trunk slammed shut behind him. Theo spun, but the attic felt smaller, walls pressing in. Downstairs, the front door hung wide, rain pooling on the threshold. Something waited outside—or had it already come in?
