"I'll stay for one more drink and then I'm due at the office," he said. "You know, I think this would make an item for the paper." He grinned and nodded toward the pandemonium.

When he was gone, I noticed it was getting dark and turned on the desk lamp. Then I saw the curtains. They were all tied in knots, except one. That was tied in three knots.

All right, I told myself, it was the wind. But I felt the time had come for me to get expert advice, so I went to the phone to call McGill. McGill is an assistant professor of mathematics at a university uptown and lives near us. He is highly imaginative, but we believe he knows everything.

When I picked up the receiver, the line sounded dead and I thought, more trouble. Then I heard a man cough and I said hello. McGill's voice said, "Alec? You must have picked up the receiver just as we were connected. That's a damn funny coincidence."

"Not in the least," I said. "Come on over here. I've got something for you to work on."

"Well, as a matter of fact, I was calling up to ask you and Molly—"

"Molly's away for the week. Can you get over here quick? It's urgent."

"At once," he said, and hung up.

While I waited, I thought I might try getting down a few paragraphs of my novel—perhaps something would come now. It did, but as I came to a point where I was about to put down the word "agurgling," I decided it was too reminiscent of Gilbert and Sullivan, and stopped at the letter "R." Then I saw that I had unaccountably hit all four keys one step to the side of the correct ones, and tore out the page, with my face red.

This was absolutely not my day.
