She moved in for the cheap rent. He bought the duplex to own the wall between them.
Maeve Callahan hasn't slept in months. A burnt-out transcriptionist with a tremor in her hands and a therapist she stopped calling back, she signs the lease on a quiet suburban duplex without asking why the rent is six hundred dollars below market.
The man on the other side of the shared bedroom wall never introduces himself. During the day, he looks through her like she's furniture — dead eyes, zero recognition, absolute indifference. But after midnight, his voice comes through the plaster. Low. Commanding. Precise enough to slow her heart rate on contact.
He tells her when to breathe. When to sleep. When to press her palms to the wall and hold still.
She obeys.
She knows what he is. She heard the violence through the plaster. She heard bones break on his floor.
She knocked to make sure the monster was okay.
Some walls don't keep you safe. They keep you close.
