I don't think they know I have a disease. I didn't have any obvious marker symptoms, like pox or a rash, and I think they put my fever and delirium down to my injuries. Wounds often became infected, and there were frequent cases of blood poisoning. There would be no reason to keep the little girls away from an injured person.

And none of them have caught it. It's been five days, and if it is a virus, the incubation period should only be twelve to forty-eight hours. Dr. Ahrens told me the most contagious period is before there are any symptoms, so maybe I wasn't contagious by the time the little girls started coming in. Or maybe this is something they've all had already, and they're immune. The steward's wife asked if I had had "the Florentine? Flahntin? fever," and Mr. Gilchrist's convinced there was an influenza epidemic in 1320. Maybe that's what I caught.

It's afternoon. Rosemund is sitting in the windowseat, sewing a piece of linen with dark red wool, and Blackie's asleep beside me. I've been thinking about how you were right, Mr. Dunworthy. I wasn't prepared at all, and everything's completely different from the way I thought it would be. But you were wrong about it's not being like a fairy tale.

Everywhere I look I see things from fairy tales: Agnes's red cape and hood and the rat's cage and bowls of porridge, and the village's huts of straw and sticks that a wolf could blow down without half trying.

The bell tower looks like the one Rapunzel was imprisoned in, and Rosemund, bending over her embroidery, with her dark hair and white cap and red cheeks, looks for all the world like Snow White.

I think my fever is back up. I can smell smoke in the room. Lady Imeyne is praying, kneeling beside the bed with her Book of Hours. Rosemund told me they have sent for the steward's wife again. Lady Imeyne despises her. I must be truly ill for her to have sent for her. I wonder if they will send for the priest. If they do, I must ask him if he knows where Gawyn found me. It's so hot in here. This part is not like a fairy tale at all. They only send for the priest when someone is dying, but Probability says there was a seventy-two per cent chance of dying of pneumonia in the 1300's. I hope he comes soon, to tell me where the drop is and hold my hand.

CHAPTER THIRTEEN

Two more cases, both students, came in while Mary was interrogating Colin on how he had got through the perimeter.

"It was easy," Colin had said indignantly. "They're trying to keep people from getting out, not getting in," and had been about to give the particulars when the registrar came in.

Mary had made Dunworthy accompany her to the casualties ward to see if he could identify them. "And you stay here," she had told Colin. "You've caused quite enough trouble for one night."

Dunworthy didn't recognize either of the new cases, but it didn't matter. They were conscious and lucid and were already giving the house officer the names of all their contacts when he and Mary got there. He took a good look at each of them and shook his head. "They might have been part of that crowd on the High Street, I can't tell," he said.

"It's all right," she said. "You can go home if you like."

"I thought I'd wait and have my blood test," he said.

"Oh, but that isn't till — " she said, looking at her digital. "Good Lord, it's after six."

"I'll just go up and check on Badri," he said, "and then I'll be in the waiting room."

Badri was asleep, the nurse said. "I wouldn't wake him."

"No, of course not," Dunworthy said and went back down to the waiting room.

Colin was sitting crosslegged in the middle of the floor, digging in his duffel. "Where's Great-Aunt Mary?" he asked. "She's a bit flakked at my showing up, isn't she?"

"She thought you were safely back in London," Dunworthy said. "Your mother told her your train had been stopped at Barton."

"It was. They made everyone get off and get on another train going back to London."

"And you got lost in the changeover?"

"No. I overheard these people talking about the quarantine, and how there was this terrible disease and everybody was going to die and everything — " He stopped to rummage further in his duffel. He took out and replaced a large number of items, tapes and a pocket vidder and a pair of scuffed and dirty runners. He was obviously related to Mary. "And I didn't want to be stuck with Eric and miss all the excitement."

"Eric?"

"My mother's livein." He pulled out a large red gobstopper, picked off a few bits of lint, and popped it in his mouth. It made a mumplike lump in his cheek. "He is absolutely the most necrotic person in the world," he said around the gobstopper. "He has this flat down in Kent and there is absolutely nothing to do."

"So you got off the train at Barton. What did you do then? Walk back to Oxford?"

He took the gobstopper out of his mouth. It was no longer red. It was a mottled bluish-green color. Colin looked critically at all sides of it and put it back in his mouth. "Of course not. Barton's a long way from Oxford. I took a taxi."

"Of course," Dunworthy said.

"I told him I was reporting the quarantine for my school paper and I wanted to get vids of the blockade. I had my vidder with me, you see, so it seemed the logical thing." He held up the pocket vidder to illustrate, and then stuffed it back in the duffel and began digging again.

"Did he believe you?"

"I think so. He did ask me which school I went to, but I just said, very offended, 'You should be able to tell,' and he said St. Edward's, and I said, 'Of course.' He must have believed me. He took me to the perimeter, didn't he?"

And I was worried about what Kivrin would do if no friendly traveller came along, Dunworthy thought. "What did you do then, give the police the same story?"

Colin pulled out a green wool jumper, folded it into a bundle, and laid it on top of the open duffel. "No. When I thought about it, it was rather a lame story. I mean, what is there to take pictures of, after all? It's not like a fire, is it? So I just walked up to the guard as if I were going to ask him something about the quarantine, and then just at the last I dodged sideways and ducked under the barrier."

"Didn't they chase you?"

"Of course. But not for more than a few streets. They're trying to keep people from getting out, not in. And then I walked about awhile till I saw a street sign I recognized."

Presumably it had been pouring rain this entire time but Colin hadn't mentioned it, and a collapsible umbrella wasn't among the items he'd rooted out of his bag.

"The hard part was finding Great-Aunt Mary," he said. He lay down with his head on the duffel. "I went to her flat, but she wasn't there. I thought maybe she was still at the tube station waiting for me, but it was shut down." He sat up, rearranged the wool jumper, and lay back down. "And then I thought, she's a doctor. She'll be at the infirmary."

He sat up again, punched the duffel into a different shape, lay down and closed his eyes. Dunworthy leaned back in the uncomfortable chair, envying the young. Colin was probably nearly asleep already, not at all frightened or disturbed by his adventures. He had walked all over Oxford in the middle of the night, or perhaps he had taken further taxis or pulled a collapsible bicycle out of his duffel, all by himself in a freezing winter rain, and he wasn't even fazed by the adventure.

Kivrin was all right. If the village wasn't where it was supposed to be she would walk until she found it, or take a taxi, or lie down somewhere with her head on her folded-up cloak, and sleep the undauntable sleep of youth.

Mary came in. "Both of them went to a dance in Headington last night," she said, dropping her voice when she saw Colin.
