Nolieti turned round when he heard us approach. "About fucking time," he spat, fixing his stare on first me, then the Doctor and then Unoure (who, I noticed, as the Doctor stuffed her kerchief back into a pocket in her jacket, was making a show of folding the black blindfold he had been told to use on her).

"My fault," the Doctor said in a matter-of-fact manner, stepping past Nolieti. She bent down at the man's rear. She grimaced, nose wrinkling, then came to the side of the apparatus and with one hand on the iron hoops of the framechair brought it squeaking and complaining round until the man was in a more conventional sitting position. The fellow looked in a terrible state. His face was grey, his skin was burned in places, and his mouth and jaw had collapsed. Little rivulets of blood had dried under each of his ears. The Doctor put her hand through the iron hoops and tried to open one of the man's eyes. He made a terrible, low groaning sound. There was a sort of sucking, tearing noise and the man gave a plaintive moan like a kind of distant scream before settling into a ragged, rhythmic, bubbling noise that might have been breathing.

The Doctor bent forward to peer into the man's face and I heard her give a small gasp.

Nolieti snorted. "Looking for these?" he asked the Doctor, and flourished a small bowl at her.

The Doctor barely glanced at the bowl, but smiled thinly at the torturer. She rotated the iron chair to its previous position and went back to look at the caged man's rear. She pulled away some blood-soaked rags and gave another grimace. I thanked the gods that he was pointing away from me and prayed that whatever the Doctor might have to do would not require my assistance.
