“Do you know that your enemies are here?” went on our hero.

“My enemies?”

“Gaff Caven and Pat Malone. But they are traveling under other names.”

“Have they seen you?”

“I think not, sir.”

Mr. Vane soon had his room assigned to him and he and our hero passed up in the elevator. As soon as they were in the apartment by themselves, Joe related what he had seen and heard.

“They are certainly on my trail,” mused Maurice Vane. “And they must have kept pretty close or they wouldn't know that I had asked you to accompany me.”

“They have some plot, Mr. Vane.”

“Have you any idea what it is?”

“No, sir, excepting that they are going to try to do you out of your interest in that mine.”
