“Matches?”

“Here, sir.”

“Light one, will you, Flannigan? I want to see the time.”

The flare showed Dallas and Flannigan bent over the timepiece. And it showed something else. The rug had been turned back from the windows which opened on the street, and the curtains had been removed. On the bare hardwood floor just beneath the windows was an array of pans of various sizes, dish pans, cake tins, and a metal foot tub. The pans were raised from the floor on bricks, and seemed to be full of paper. All the chairs and tables were pushed back against the wall, and the bric-a-brac was stacked on the mantel.

“Half an hour yet,” Dal said, closing his watch. “Plenty of time, and remember the signal, four short and two long.”

“Four short and two long—all right, sir.”

“And—Flannigan, here’s something for you, on account.”

“Thank you, sir.”

Dal turned to go out, tripped over the rug, said something, and passed me without an idea of my presence. A moment later Flannigan went out, and I was left, huddled against the wall, and alone.

It was puzzling enough. “Four long and two short!” “All but the powder!” Not that I believed for a moment what Max had said, and anyhow Flannigan was the sanest person I ever saw in my life. But it all seemed a part of the mystery that had been hanging over us for several days. I felt my way across the room and knelt by the pans. Yes, they were there, full of paper and mounted on bricks. It had not been a delusion.
