"Don't really want to die just yet," I muttered.

"Then sprine it will have to be."

I tried to yell then, but it came out as a whimper. I tried to fight free of my lead suit, but to no avail. Then came some kind of schism: the me fighting for life and another me analytically inspecting past memories. I remembered that terse individual aboard a sailing ship on Spatterjay telling me, "Now you're buggered." Then, with seemingly no transition I was standing on Crematorius, the Mercury station from which they launched the bodies of the dead into the sun.

"Why?" I asked.

"That is not a question you need to ask," my father replied.

No, it wasn't—just one I would have to face in the future. It was accepted wisdom that, though it was possible to live forever, people reaching their second century often got bored with life. Ennui killed them. Sometimes it was utterly conscious—a quiet suicide at home or else something often spectacular and messy—other times it manifested in an impulse towards increasingly dangerous pursuits. My mother took up free climbing without aug link, locator or any of the usual safety equipment. She did Everest, many of them do, but her attempt at the Eiger resulted in the mess now sealed inside a glass coffin, ready to be fired into the sun.

Of course, born to my parents when they were in their fifties I hit my similar watershed fifty years after that funeral. I lost interest in U-space mechanics, which I had been pursuing avidly for about thirty years, and decided I would like to go sailing. Inevitably I chose to go sailing on oceans full of lethal predators, which were located on the planet Spatterjay. But I survived and, after a further 400 years, discovered that 'long habit of living' of which the Old Captains there are so fond.

I did not want to die. I didn't want sprine. Sprine means death to those infected by the Spatterjay virus. Sprine on the blade of a dagger…

"Screw you! Screw you and your shag-nasty woman. I'll eat your fucking eyes!" He was big, a 300-year-old hooper who had thrown his Captain's wife over the side of the ship, so it wasn't exactly murder. She would continue drifting through the ocean, body stripped down to bone, but alive and forever suffering, unless someone rescued her, or until her mind went. The penalty remained the same, however. The Captain stepped up to him as he struggled against chains and manacles thick enough to hold an elephant, and drove the sprine-tainted dagger up under his ribcage.

"Oh," said the hooper. "Oh bugger."

Black fluid flowed from the wound. He began shuddering as if being electrocuted, splits developed throughout his body and slowly he began to fall apart, like a building being dismantled brick by brick. And in the end all that remained of him was a pile of steaming offal.

Sprine.

My suffering lasted four days, every hour filled with hallucination and many memories I would rather not recall. Slowly, very slowly, I began to return to myself—disparate fragments of my mind slowly melding together until I became conscious. My body burned. Someone had sanded off the outer layer of my skin and injected chilli oil into my depleted veins. Gritty eyes finally open, I surveyed my surroundings.

The room looked like the inside of a walnut shell, but green and yellow, with light permeating the walls. Nil gee, I noticed. I was strapped down to some organic pulsing object that smelt of clams. Something sucked at my anus and I could feel the intrusion of a catheter. Hoisting myself up a little, I saw a ribbed tube snaking down from between my legs and disappearing into the living mattress. But this wasn't what riveted my attention, for I hardly recognised my own body. It was starveling thin, ribs plainly evident under sagging skin, and jaundice-yellow. Great. Only as I lay back did I feel something squirm on my face and at the back of my throat. Tubes retracted from my nostrils and flipped aside like beached sand eels. I saw them being sucked back into the grey veined flesh pillowing my head.

"Hey," I managed weakly. "Hey."

A vaginal door opened in the wall and Slog stuck his head through. I raised a hand to try sign language, but it shook so much I gave up.

"I'll get someone," Slog clattered, and disappeared.

My thoughts ran clear but I felt incredibly weak. Obviously I was aboard a Brumallian ship, and that ship was now in space. Had I hallucinated that voice talking about sprine? I thought not, but couldn't fathom what had happened. The vaginal door parted again and Rhodane entered, pulling herself along by struts jutting out from the wall to reach over beside my bed.

"You're alive," I said.

She pressed her hand to a bulky lump concealed under her clothing, just over her right hip. "The bullet lost much of its momentum, and broke apart as it passed through you. Some fragments penetrated, that is all."

I wondered what else might have penetrated her. Like many viruses of Earth the Spatterjay virus could not long survive outside its host. However, a bullet passing through me first and then entering her might serve to infect her with it, or with IF21, or both.

"She is not infected with either virus…probably," said a voice.

I recognised it as the same voice that recently talked to me of sprine, and now recognised it from before that. "Are you going to keep on hiding?" I asked in English.

Tigger materialised at the foot of my living bed. "Their own surgeon removed the pieces of the bullet. I used nanoscopic techniques to ensure the removal of any viral fragments, and then screened her blood and other bodily fluids."

I tried to hoist myself up again, but could not seem to find the strength even though I was not fighting gravity. Rhodane reached down and touched something beside the bed. The part behind my back folded up smoothly to bring me into a sitting position.

After a rush of dizziness I said, "Perhaps you'd better start with Vertical Vienna," switching to speak in Sudorian for Rhodane's benefit.

"It would seem that Fleet has obtained technology enabling it to detect me despite my chameleonware." Tigger now spoke Sudorian too. "Ironfist fired a missile at the city—one deliberately hardened so I could not interfere with it from a distance—and when I closed with it, someone aboard that ship pressed the detonation button."

"Yet you are here," I said.

"The smaller portion of me is here," Tigger replied. "As you will recollect, this form you see before you is not all of me."

"The sphere," I managed.

"Yes. By the time I was again able to move, a second missile had already been fired into Vertical Vienna. Through Brumal coms I was able to track you down and came here to this ship as they were bringing you aboard."

I glanced at Rhodane, who was staring at Tigger intently. "He revealed himself to you."

She turned towards me. "You were dying. We sealed your wounds as best we could and made the most of the medical technologies aboard, but to no avail. Tigger then appeared, told us what he was, and took over."

"What did you do, Tigger? I heard something…about sprine."

"As you have known for some time, any injuries done to you enable IF21 to gain headway within your body. Your gunshot wound caused something like open warfare between IF21 and the Spatterjay virus, both of them using up your physical resources in the process. Had I left matters as they were, nothing would have remained of you but the two virus forms, and perhaps a few bones. One of them had to go. I could do nothing about IF21, but sprine effectively kills the Spatterjay virus. I showed the Brumallians how to synthesise that organic chemical, then we fed it to you in very small doses, killing off the Spatterjay virus and enabling IF21 to win the war."

I tried to absorb that news, but felt so very tired. "But sprine kills…"
