"Come on! We'll get 'em!" shouted Roy, turning quickly and starting after his captor and the confederate.

But he was too late.

Wakely slammed the door of the room shut, and locked it, and Roy knew it would be useless to try and open it.

"Break the door down!" exclaimed Mortimer De Royster. "We can catch them!"

"The door's too strong," replied Roy.

"Then we're caught!"

"Yes, but don't worry. I can go down the lariat the same as I did before."

"Perhaps you can, but I can't my dear fellow."

"Oh, I'll come up the stairs and open the door for you, if the key's there. Say, but how did you get here, anyhow?"

"I came after you. I've been tracing you for hours. What does it all mean, Roy? Why did they take you a prisoner?"
