“You could be arrested for that,” Brad reminded him.

“I know,” the man admitted. “I figured that sooner or later I’d be caught here. I’ll move out today. I’d hoped to stay a little longer—but never mind.”

“You should tell us your name.”

“I should,” the man agreed. “Just call me Mr. Smith. When the right time comes, you’ll learn my true name.”

Brad and Dan were becoming more confused each moment. They liked the friendly stranger, but could not understand why he acted so mysteriously. If he had no criminal record, why should he hesitate to reveal his name?

“What happened Halloween night?” Dan asked curiously. “You must have played ghost.”

Mr. Smith laughed aloud at the recollection. “I heard those boys speaking up the stairway,” he revealed. “I waited until they were nearly in the belfry. Then I popped out with a blanket over my face. I made moaning sounds and wild gestures. Those kids bolted out of here like a streak of lightning.”

“From time to time, we’ve heard the bell tap,” Dan went on. “Were you responsible?”

“Afraid I’ll have to plead guilty. Once when the kids were here, I hit the bell by accident. The other times I tapped it on purpose. I didn’t want to scare the kids too much—only wanted to keep them from playing around here.”

Brad had been gazing thoughtfully at the stranger, thinking hard. If the man had lived in the belfry for three weeks, he must have observed a great many persons come and go. No wonder he seemed personally acquainted with the members of Den 2!
