The Notes on the Walls

The first day and night in 4B

Nadia moved into Harrow House and found the apartment covered in handwritten rules left by Sylvie Marsh, the previous tenant. Beneath a loose floorboard she discovered Sylvie’s water-damaged diary, which suggested the rules documented a responsive presence rather than a prank; after noticing a delayed reflection and movement inside the wall, Nadia followed the seven-count rule when knocking came at 3 a.m.—only for the sound to begin within the bedroom wall.
