She wanted to cry out and tears came to her eyes. She saw two more nails. They were thick and looked long and old, and had been hammered through Tanith’s collarbones to keep her upright in the chair. A fifth nail entered Tanith’s right leg just above the knee and drove down and through her left, pinning them together.

Kenspeckle was talking again, but Valkyrie wasn’t listening to the words. She stared at her friend. She couldn’t breathe. She was suddenly too hot in the ventilation shaft and it was tight, far too tight, and close. She had to get out. She had to back out the way she had come, and she had to smash down that door and rip that Remnant out of Kenspeckle’s body. It was the only thing to do. It was the only thing that mattered.

Valkyrie tried moving backwards, the anger churning. It was bubbling, boiling, rising in her throat. She wasn’t moving. She couldn’t move backwards. Panic mixed with anger and fuelled it, and a small voice somewhere in Valkyrie’s mind told her to calm down, but she wasn’t listening.

She moved on, crawling, moving quickly, grunting, not caring if that thing that was not Kenspeckle Grouse could hear her or not. And then there was no more ground and Valkyrie was suddenly sliding downwards. She cursed as she went, trying to snag an intersecting crawlspace, but only succeeded in taking a rat’s nest with her. The rats squealed beneath and beside her and she lashed out, trying to throw them off. Her head struck stone. Her body twisted.

Below her, brightness and heat.

She tumbled through the gap and fell about a metre. There was another gap directly below it and she reached out instinctively, spreading her arms and legs and jamming herself over the opening, stopping herself from falling through to the room below.

Valkyrie looked down on to a large wooden table, and the partially inflated skin of the Hollow Man that lay upon it.

Another Hollow Man lumbered into view, carrying a bucket of slop and what looked like entrails. It didn’t look up and Valkyrie didn’t make a sound. It went to the furnace built into the wall, the only source of light in the room, and opened the metal grille above the flames. Spilling some and not caring, the Hollow Man poured the slop into the furnace. Valkyrie’s muscles were beginning to ache.
