Heat rises, as is commonly known, but not always without effort. In Slough House, its ascent is marked by a series of bangs and gurgles, an audible diary of a forced and painful passage through cranky piping, and if you could magic the plumbing out of the structure and view it as a free-standing exoskeleton, it would be all leaks and dribbles: an arthritic dinosaur, its joints angled awkwardly where fractures have messily healed; its limbs a mis-matched muddle; its extremities stained and rusting, and weakly pumping out warmth. And the boiler, the heart of this beast, wouldn’t so much beat as flutter in a trip-hop rhythm, its occasional bursts of enthusiasm producing explosions of heat in unlikely places; its irregular palpitations a result of pockets of air straining for escape. From doors away you can hear its knocking, this antiquated heating system, and it sounds like a monkey-wrench tapping on an iron railing; like a coded message transmitted from one locked cell to another.
It’s a wasteful, unworkable mess, but then this shabby set of offices—hard by Barbican underground station, on Aldersgate Street, in the borough of Finsbury—isn’t exactly noted for its efficiency, of equipment or personnel. Indeed, its inhabitants might as well be banging on pipes with spanners themselves for all their communication skills are worth, though on this cold January morning, two days after an appalling act at Westacres shopping centre claimed upwards of forty lives, other noises can be heard in Slough House. Not in Jackson Lamb’s room, for once: of all the building’s occupants, he may be the one most obviously in tune with its rackety plumbing, being no stranger to internal gurglings and sudden warm belches himself, but for the moment his office is empty, and his radiator its sole source of clamour. In the room opposite, though—until a few months back, Catherine Standish’s; now Moira Tregorian’s—there is at least some conversation taking place, though of a necessarily one-sided nature, Moira Tregorian currently being the room’s sole occupant: her monologue consists of single, emphatic syllables—a “tchah” here, a “duh” there—interspersed with the odd unfractured phrase,
Meanwhile, from the landing below, other noise floats up: a murmur from the kitchen, where a kettle has lately boiled, and a recently opened fridge is humming. In the kitchen are River Cartwright and Louisa Guy, both with warm mugs in their hands, and Louisa is maintaining a nearly unbroken commentary on the trials and tribulations accompanying the purchase of her new flat. This is quite some distance away, as London flats tend to be if they’re affordable, but the picture she paints of its size, its comfort, its uncluttered surfaces, is evidence of a new contentment that River would be genuinely glad to witness, were he not brooding about something else. And all the while, behind him, the door to his office creaks on a squeaky hinge, not because anyone is currently using it, but in general protest at the draughts that haunt Slough House, and in a more particular complaint directed at the commotion arising from the next floor down.
