Dunworthy put him on, and he launched into a recital of his gifts, down to and including the motto in his cracker. "Mr. Dunworthy gave me a book about the Middle Ages." He held it up to the screen. "Did you know they cut off people's heads for stealing and stuck them up on London Bridge?"

"Thank her for the muffler, and don't tell her you're running errands for the vicar," Dunworthy whispered, but Colin was already holding the receiver out to him. "She wants to speak to you again."

"It's clear you're taking good care of him," Mary said. "I'm very grateful. I haven't been home yet, and I should have hated him to be alone on Christmas. I don't suppose the promised gifts from his mother have arrived?"

"No," Dunworthy said cautiously, looking at Colin, who was looking at the pictures in the Middle Ages book.

"Nor telephoned," she said disgustedly. "The woman hasn't a drop of maternal blood in her body. For all she knows, Colin might be lying in hospital with a temp of forty degrees, mightn't he?"

"How is Badri?" Dunworthy asked.

"The fever was down a bit this morning, but there's still a good deal of lung involvement. We're putting him on synthamycin. The South Carolina cases have responded very well to it." She promised to try to come over for Christmas dinner and then rang off.

Colin looked up from his book. "Did you know in the Middle Ages they burned people at the stake?"

Mary didn't come nor telephone, and neither did Andrews. Dunworthy sent Colin over to hall for breakfast and tried phoning the tech, but all the lines were engaged, "due to the holiday crush," the computer voice said, obviously not reprogrammed since the beginning of the quarantine. It advised him to delay all nonessential calls until the next day. He tried twice more, with the same result.

Finch came over, bearing a tray. "Are you all right, sir?" he said anxiously. "You're not feeling ill?"

"I'm not feeling ill. I'm waiting for a trunk call to come through."

"Oh, thank goodness, sir. When you didn't come over for breakfast I feared the worst." He took the rain-spotted cover off the tray. "I'm afraid it's a poor sort of Christmas breakfast, but we're nearly out of eggs. I don't know what sort of Christmas dinner it will be. There isn't a goose left inside the perimeter."

It actually seemed to be quite a respectable breakfast, a boiled egg, kippers, muffins with jam.

"I tried for a Christmas pudding, sir, but we're nearly out of brandy," Finch said, pulling a plastic envelope out from under the tray and handing it to Dunworthy.

He opened it. On top was an NHS directive headed: "Early Symptoms of Influenza. 1.) Disorientation. 2.) Headache. 3.) Muscle Aches. Avoid contracting it. Wear your NHS regulation face mask at all times."

"Face mask?" Dunworthy asked.

"The NHS delivered them this morning," Finch said. "I don't know how we're going to manage the washing up. We're nearly out of soap."

There were four other directives, all similar in tone, and a note from William Gaddson with a printout of Badri's credit account for Monday, the twentieth of December, attached. Badri had apparently spent that missing time from noon to half-past two Christmas shopping. He had purchased four books, paperback, at Blackwell's, a muffler, red, and a digital carillon, miniature, at Debenham's. Wonderful. That meant dozens and dozens more contacts.

Colin came in carrying a napkinful of muffins. He was still wearing his paper crown which was a good deal the worse for the rain.

"It would reassure everyone, sir," Finch said, "if after your call comes through, you'd come over to hall. Mrs. Gaddson particularly is convinced you've come down with the virus. She said you'd contracted it through poor ventilation in the dormitories."

"I'll put in an appearance," Dunworthy promised.

Finch went to the door and then turned back. "About Mrs. Gaddson, sir. She's behaving dreadfully, criticizing the college and demanding that she be moved in with her son. She's completely undermining morale."

"I'll say," Colin said, dumping the muffins on the table. "The Gallstone told me hot breads were bad for my immune system."

"Isn't there some sort of volunteer work she could do at Infirmary or something?" Finch asked. "To keep her out of college?"

"We can hardly inflict her on poor helpless flu victims. It might kill them. What about asking the vicar? He was looking for volunteers to run errands."

"The vicar?" Colin said. "Have a heart, Mr. Dunworthy. I'm working for the vicar."

"The priest from Holy Re-Formed then," Dunworthy said. "He's fond of reciting the Mass in Time of Pestilence for morale. They should get along swimmingly."

"I'll phone him straightaway," Finch said, and left.

Dunworthy ate his breakfast, except for the muffin, which Colin appropriated, and then took the empty tray over to hall, leaving orders for Colin to come get him immediately if the tech rang up. It was still raining, the trees black and dripping and the Christmas tree lights spotted with rain.

Everyone was still at table except for the bellringers, who stood off to one side in their white gloves, their handbells on the table in front of them. Finch was demonstrating the wearing of the NHS regulation masks, pulling off the tapes at either side and pressing them to his cheeks.

"You don't look well at all, Mr. Dunworthy," Mrs. Gaddson said. "And no wonder. The conditions in this college are appalling. It is a wonder to me that there has not been an epidemic before this. Poor ventilation and an extremely uncooperative staff. Your Mr. Finch was quite rude to me when I spoke to him about moving into my son's rooms. He told me I had chosen to be in Oxford during a quarantine, and that I had to take whatever accommodations I was given."

Colin came skidding in. "There's someone on the telephone for you," he said.

Dunworthy started past her, but she placed herself solidly in his way. "I told Mr. Finch that he might be content to stay at home when his son was in danger, but that I was not."

"I'm afraid I'm wanted on the telephone," Dunworthy said.

"I told him no real mother could fail to go when her child was alone and ill in a far away place."

"Mr. Dunworthy," Colin said. "Come along!"

"Of course you clearly have no idea what I'm talking about. Look at this child!" She grabbed Colin by the arm. "Running about in the pouring rain with no coat on!"

Dunworthy took advantage of her shift in position to get past her.

"You obviously care nothing about your boy's catching the Indian flu," she said. Colin wrenched free. "Letting him gorge himself on muffins and go about soaked to the skin."

Dunworthy sprinted across the quad, Colin at his heels.

"I will not be surprised if this virus turns out to have originated here in college," Mrs. Gaddson shouted after them. "Sheer negligence, that's what it is. Sheer negligence!"

Dunworthy burst into the room and snatched up the phone. There was no picture. "Andrews," he shouted. "Are you there? I can't see you."

"The telephone system's overbooked," Montoya said. "They've cut the visual. It's Lupe Montoya. Is Mr. Basingame salmon or trout?

"What?" Dunworthy said, frowning at the blank screen.

"I've been calling fishing guides in Scotland all morning. When I could get through. They say where he's gone depends on whether he's salmon or trout. What about friends? Is there someone in the university he goes fishing with who might know?"

"I don't know," Dunworthy said. "Ms. Montoya, I'm afraid I'm waiting for a most important — "

"I've tried everything else — hotels, inns, boat rentals, even his barber. I tracked his wife down in Torquay, and she said he didn't tell her where he was going. I hope that doesn't mean he's off somewhere with a woman and not really in Scotland at all."
