Then, but not without many misgivings, the girls set out to try to find Russ.
"We can call up the studio on the telephone," suggested Alice, as she and her sister reached the street. "That will be the quickest way. If Russ isn't there they may be able to tell us where he is, or Mr. Pertell may know where the model is—I mean the machine shop where the apparatus is being turned out."
"That's so," agreed Ruth. "Why, we could have used one of the telephones in the apartment!"
"No, some of the neighbors would overhear us, and we don't want that."
"Why not?" Ruth wanted to know.
"Because you can't tell but one of those men may be watching this place, and some of the neighbors may be in league with them. Besides, all the telephones here are on party wires, and when you talk over one, some of the other subscribers on the same circuit may listen, for all we can tell. It isn't safe."
"My! You think of everything!" exclaimed Ruth, admiringly. "How do you manage it?"
"Oh, it just seems to come to me," replied Alice, with a laugh. "Come on," she added, after they had walked a little way. "There's a drug store and there's a telephone booth in it. Do you want to talk to Russ, in case he's there?"
"Oh, no, you'd better," responded Ruth, blushing.
"I will not. I'll call up the studio, but if he's there I want you to be the one to tell him. He'll appreciate it."
