“But if you remain you will be nabbed,” remonstrated the Jew.

“You said the girl was to come first?”

“Yes.”

“Then I shall wait, and when she comes—well.”

The ruffian’s features were distorted with passion.

“Woe to you, Jew,” Skip continued, “if her coming is not followed by that of the police. Pull off, boys; some one is knocking at the door.”

Again the knock was repeated.

Hastily closing the window, the rascal went to the door.

“Let me in! Let me in, I say.”

“That is not her voice,” muttered Skip.
