Thanks to the unknown girl, the scheme had been frustrated.

For a moment, Harry was tempted to beat against the revolving wall, to attract the attention of the policemen. But on second thought he decided to wait.

There were a dozen persons in that room who would testify that he was the cause of the trouble. He could be framed with ease.

After all, he was safe here for the time being. Why should he invite more trouble?

The girl had promised to return, Harry had confidence in that promise.

He scanned the lighted room. There was not a woman in the place, let alone the one he sought. The feminine patrons had evidently been escorted out; the girl had probably slipped away in the darkness.

Two rough-looking waiters began to clear up the debris, and the policemen left. Quiet was restored. The few patrons who remained took their places at the tables, and the waiters brought them drinks.

Volovick remained. So did the man who had drawn the knife. The others — Harry could see nearly a dozen of them — were fit companions for those men.

It would be suicide to attempt an escape now. There was only one thing to do — wait until the gang had gone. Then, Harry hoped, the girl would return to release him.

Some of the men were engaged in discussion. Harry fancied that they were talking about him. Two men came in from the entrance. They talked with Volovick. They had probably been stationed outside to prevent Harry’s escape.
