The blinds were closed, and over them had been nailed several heavy slats. The room was rather cold, and they had only a small lamp for illumination.

When Pepper awoke he thought somebody was whistling in his ear. He listened intently and soon discovered that the whistling came through the keyhole of the door.

“Who is there?” he asked, rising.

“Is that you, Pep?” came in Andy’s voice.

“Yes.”

“Is Jack there, too?”

“Yes.” And now the Imp aroused his chum.

“What is it all about anyway? Our crowd is all upset over it,” continued Andy, in a low voice.

Pepper and Jack told as much as they knew, and their acrobatic friend listened with interest.

“I’d like to let you out, but the door is locked and I haven’t any key,” went on Andy.
