Unaware herself of the absurdity of her deductions, Betty raised the heavy gun and pointed it toward the bed. As well as she could tell, she was aiming under the bed. She shut her eyes tight and fired.

The gun kicked unmercifully, and Betty ejaculated a loud "Ow!" which was lost in the babble of sound that immediately followed the shot. There was the sound of breaking glass under the bed, a shrill scream from Mrs. Peabody, and the thunderous bellow of Mr. Peabody demanding: "What in Sam Hill are those varmints up to now?" Evidently he attributed the racket to Wapley and Lieson, who had been known to come home late from Glenside.

In a few minutes they were all gathered at Betty's door, Bob open-mouthed and speechless, the two men sleepily curious, the Peabodys loudly demanding to know what the matter was.

"Are you hurt, Betty?" asked Mrs. Peabody anxiously. "Where did you get the gun, dear? Did something frighten you?"

"It's a burglar!" declared Betty. "I heard him under the bed! But I got him, I know I did!"

"Light the lamp and look under the bed, Bob," commanded Mr. Peabody harshly. "I don't believe this burglar stuff, but the girl's shot off a good charge of buckshot, no doubt of that. Find out what she hit."

Bob lit the lamp and stooped down to look. Then his lips twitched.

"Rat!" he announced briefly. "A big one."

"Haul him out," directed Lieson. "Let's have a look at him."

Betty had shrunk inside the doorway when the lamp was lit, conscious of her attire, and now she managed to reach her dressing gown and fling it around her.
