“You can clean your section later,” Brad consented. “Just so you get the job done in the next day or so. By the way, you told Mr. Kain about the broken window?”

“No, I didn’t.”

Then, as Brad fixed him with a disapproving gaze, Ross added with a flare of temper: “I didn’t get a chance to do it. I’ll tell him the next time he comes around.”

“Don’t bother,” Brad replied shortly. “I’ll tell him myself when I see him.”

As the sun rose higher, all the Cubs began to look forward to lunch. Unaccustomed to such heavy work, they felt the need of a rest.

“All right, fellows, knock off,” Mr. Hatfield advised them. “You’ve put in a big morning. Rest awhile and then we’ll eat.”

Dan and Brad took advantage of the lull to roam around the castle. Both boys were fascinated by its unusual design and old-world appearance.

“It’s queer about that laughter I heard from the woods,” Dan commented thoughtfully. “We’ve seen no one, and yet I’m sure someone was watching us.”

“Maybe it came from the castle,” Brad suggested, gazing up at the shadowy turrets. “With that window broken, any tramp could get inside.”

“How about taking another look?” Dan proposed. “We’ll have time for a quick search through the house before lunch.”
