Slough House

Westacres

What it is

A shopping centre on London’s western fringe, built around a fountain hub where four corridors meet. The pages give it no borough, no owner and no size; they give it a plan, and the plan is the point. Every avenue in the building funnels through the fountain, which is why a Community Regulation Officer called Samit Chatterjee keeps his post there, and why the bomb is placed where the crowd is thickest and the exits furthest away.

The only other physical details are seasonal and slightly wrong: on the first working day of the year the windows are dressed for a spring that has not arrived, and the wet floor makes every passage hazardous. It is a building dressed for a better day than the one it gets, staffed by officers in the same ambiguous position — security guards by another name, with a radio and no authority to stop anything.

Why it matters

Westacres is the book’s absent centre. It is dramatised once, from inside, by a man who dies in it, and every subsequent chapter is a reaction to it: an alert level, a budget, a COBRA, a warrant, a shoot-to-kill order, a cleanup. Herron withholds the explanation until the final chapter and then supplies it in a single sentence, which is the shape of the whole novel — an atrocity that turns out to have been assembled from the Service’s own inventory.

That is the argument the place carries. The identity was a cold body issued when its carrier was two years old; the Semtex came from an armoury raid in the early nineties; the operator was raised by a Service-funded programme in France. Nothing at Westacres was foreign except the target. Taverner’s formula — no involvement, product misappropriated — is technically true and morally worthless, and the shopping centre is where the difference between those two things is measured in bodies.

It is also the book’s comment on cover. The weapon was delivered inside a crowd: a ghetto-blaster, a flash mob, three boys who thought they were supplying music. The ordinary is the camouflage, which is why the prologue spends its length on wet floors and shop windows before it spends a line on the bomb.
