‘Thank you, Apothecary.’

‘Ebhoe,’ he said, ‘I think it is fair to say we cannot save any who have been infected now. We can only hope to vaccinate the healthy against infection. I have prepared a serum for that purpose, and I will inoculate all healthy men with it. You will help me. And you will be first. So I can be sure not to lose you.’

I hesitated. He came forwards with the syringe, and I started to pull up my sleeve.

‘Open your jacket and tunic. It must go through the stomach wall.’ I reached for my tunic clasps.

And saw it. The tiniest thing. Just a tiny, tiny thing. A greenish-yellow blister just below Valis’ right ear.

Ebhoe fell silent. The air seemed electrically charged. Inmates in neighbouring cells were thrashing, restless, and some were crying out. At any moment, the novitiate wardens would come.

‘Ebhoe?’ I called through the slit.

His voice had fallen to a terrified whisper, the whisper of a man who simply cannot bear to put the things haunting his mind into words.

‘Ebhoe?’

Keys clattered nearby. Lamplight flickered under a hall door. Ioq was banging at his cell door and growling. Someone was crying, someone else was wailing in a made-up language. The air was ripe with the smell of faeces, sweat and agitated fear.

‘Ebhoe!’

There was no time left. ‘Ebhoe, please!’

‘Valis had the Torment! He’d had it all along, right from the start!’ Ebhoe’s voice was strident and anguished. The words came out of the slit as hard and lethal as las-fire. ‘He had spread it! He! Through his work, his vaccines, his treatments! He had spread the plague! His mind had been corrupted by it, he didn’t know what he was doing! His many, many vaccines had failed because they weren’t vaccines! They were new strains of the Torment bred in his infirmium! He was the carrier: a malevolent, hungry pestilence clothed in the form of a noble man, killing thousands upon thousands upon thousands!’

I went cold. Colder than I’d ever been before. The idea was monstrous. The Torment had been more than a waster of lives; it had been sentient, alive, deliberate... planning and moving through the instrument it had corrupted.

The door of Ioq’s cell was bulging and shattering. Screams welled all around, panic and fear in equal measure. The entire hospice was shaking with unleashed psychoses.

Lamps flashed at the end of the block. Novitiates yelled out and ran forward as they saw me. They would have reached me had not Ioq broken out again, rabid and slavering, throwing his hideous bulk into them, ripping at them in a frenzy.

‘Ebhoe!’ I yelled through the slit. ‘What did you do?’
