The answers only partially satisfied Ma Harper. Evidently she was afraid that Penny might be an investigator, for she debated a moment. Then she said: “You wait here until I talk to someone.”

“But I really must be leaving.”

“You wait here, I said!” Ma Harper snapped. “Maybe you’re okay, but I ain’t takin’ no chances on you getting me into trouble about these stockings. Wait until I talk to Joe.”

Leaving Penny on the balcony, she went out by way of the front living room door. After it had closed, there was a sharp little click which made the girl fear she had been locked in.

The truth was quickly ascertained. The door was locked. For an instant, Penny was frightened, but she told herself she was not really a prisoner. There were windows she could unfasten, and another door at the rear of the house.

Intending to test it, she went quickly through the kitchen. Voices reached her ears. Evidently Ma Harper and the two men were standing close to the door, and although speaking in low tones she could hear most of the conversation.

“The girl may be all right, but I think she was sent here to spy!” Ma reported. “If we let her go, she may bring the police down on us!”

“And if you try to hold her here, you’ll soon be in trouble!” one of the men answered. Penny thought the voice was that of Clark Clayton. “You and this petty stocking business of yours! We warned you to lay off it.”

“Sure, blame me!” Ma’s voice rose angrily. “The truth is, you’re getting scared of your own racket. I was sellin’ stockings and makin’ a good, safe income until you come along and talked my husband into lettin’ you store your loot in our basement. Well, I’ve made up my mind! You’re gettin’ the stuff out of here tonight, and you’re not bringing any more in!”

“Okay, okay,” growled Sweeper Joe. “Just take it easy, and quit your yippin’. We’ll move the stuff as soon as it gets dark. Fact is, we’ve made a deal with a guy that runs a junk shop near the factory. He’s offered us a good price. We had to play along slow and easy to be sure he wasn’t tied up with the cops.”
