"I say," he said, "it looks as if—I wonder. I hope you haven't."

"What?"

"Mumps. It sounds jolly like it."

"Mumps! Of course I've not. Why should I?"

Allardyce produced a letter from his pocket. "I got this from Keith, the Ripton captain, this morning. You know they've had a lot of the thing there. Oh, didn't you? That was why they had such a bad team out."

"Bad team!" murmured Drummond.

"Well, I mean not their best team. They had four of their men down with mumps. Here's what Keith says. Listen. Bit about hoping we got back all right, and so on, first. Then he says—here it is, 'Another of our fellows has got the mumps. One of the forwards; rather a long man who was good out of touch. He developed it a couple of days after the match. It's lucky that all our card games are over. We beat John's, Oxford, last Wednesday, and that finished the card. But it'll rather rot up the House matches. We should have walked the cup, but there's no knowing what will happen now. I hope none of your lot caught the mumps from Browning during the game. It's quite likely, of course. Browning ought not to have been playing, but I had no notion that there was anything wrong with him. He never said he felt bad.' You've got it, Drummond. That's what's the matter with you."

"Oh, rot," said Drummond. "It's only a chill."

But the school doctor, who had looked in at the house to dose a small Seymourite who had indulged too heartily in the pleasures of the table, had other views, and before lock-up Drummond was hurried off to the infirmary.

Sheen went to Drummond's study after preparation had begun, and was surprised to find him out. Not being on speaking terms with a single member of the house, he was always out-of-date as regarded items of school news. As a rule he had to wait until Jack Bruce told him before learning of any occurrence of interest. He had no notion that mumps was the cause of Drummond's absence, and he sat and waited patiently for him in his study till the bell rang for prayers. The only possible explanation that occurred to him was that Drummond was in somebody else's study, and he could not put his theory to the test by going and looking. It was only when Drummond did not put in an appearance at prayers that Sheen began to suspect that something might have happened.
