Slough House

The cellar

What it is

Where Hassan Ahmed is held: damp, dark, with a door at the top of the stairs and a kitchen above it. Not a dungeon — a room in an ordinary house, which is what makes it frightening.

Why it matters

The novel cuts to the cellar at regular intervals, and those cuts are its clock. Every return measures how much time is left, and every return narrows the space: cellar, kitchen, boot of a car, trees.

Open questions

Whose house it is, and how Alan Black acquired it — the Roupell Street property turns out to be a Civil Service sales portfolio, squatted without a footprint.
