The two men watched him leave. When the sound of his footsteps died away, they detached themselves from the wall, unhooked the ladder and lowered it into the pit. As the prisoner started moaning that he had had enough, the big man hurried down, made a shushing gesture and clubbed him hard on the head. Two minutes later the ladder was back on the wall and the big man, now carrying a black duffel bag across his shoulders, followed his accomplice out in the maze of corridors. Silently, they made their way through twists and turns until they reached an open sewer grate.
The big man dumped the bag down in the hole and sat on the ledge. “Now get back to your post,” he whispered, “be ready for the next extraction.” Lithe as a tiger, he jumped in the dark tunnel. Dragging the grate back in place, his accomplice wondered in what sort of unholy mess he had gotten himself into.
