Once inside the troops moved to either side of the wardrobe, leaving one man to unstrap a huge sledgehammer from his back. He swung it at the old wood, dissolving the wardrobe in three huge strokes, uncovering a hole in the wall that emitted the chugging of a steam engine and fitful oil-lamp light.

Two of the officers disappeared into the secret room. There was a muffled shout and the sound of repeated hammering thuds. Benjamin Flex came flying through the crumbling hole, his body twisting, beads of blood hitting his grimy walls in radial patterns. He hit the floor head first and shrieked, tried to scrabble away, swearing incoherently. Another officer reached down and lifted him by the shirt with steam-enhanced strength, shoving him against a wall.

Ben gibbered and tried to spit, staring at the impassive blue-masked face, intricate smoked goggles and gasmask and spiked helmet like the face of some insectile dæmon.

The voice that emerged from the hissing mouthparts was monotonous, but quite clear.

“Benjamin Flex, please give your verbal or written assent to accompany myself and other officers of the New Crobuzon militia to a place of our choosing for the purposes of interview and intelligence gathering.” The militiaman slammed Ben against the wall, hard, eliciting an explosive burst of breath and an unintelligible bark. “Assent so noticed in presence of myself and two witnesses,” the officer responded. “Aye?”

Two of the militiamen behind the officer nodded in unison and responded: “Aye.”

The officer cuffed Ben with a punishing backhand blow that dazed him and burst his lip. His eyes wavered drunkenly and he dribbled blood. The hugely armoured man swung Ben up over his shoulder and stomped from the room.

The constables who had entered the little print-room waited for the rest of the squad to follow the officer back out into the corridor. Then, in perfect time, they each pulled a large iron canister from their belts and pushed the plungers that set in motion a violent chymical reaction. They threw the cylinders into the cramped room where the construct still cranked the printing press handle in an endless, mindless circuit.

The militiamen ran like ponderous bipedal rhinos down the corridor after their officer. The acid and powder in the pipebombs mixed and fizzed, flared violently, ignited the tightly packed gunpowder. There were two sudden detonations that sent the damp walls of the building shuddering.

The corridor jacked under the impact, as innumerable gobbets of flaming paper spewed from the doorway, with hot ink and ripped snatches of pipe. Twists of metal and glass burst from the skylight in an industrial fountain. Like smouldering confetti, snippets of editorials and denunciations were sprinkled over the surrounding streets. WE SAY, said one, and BETRAYAL! another. Here and there the banner title was visible, Runagate Rampant. Here it was torn and burning, only a fragment visible.
