"Were the lights on when you went in there?" asked Nestor.

"Yes," was the reply.

"And you switched them off?"

Scoby nodded and glanced toward Felix,

"How long was it after you left the room that Fremont came up?"

Both men refused to make any definite statement as to this, and Nestor saw that they were concealing something, that he had struck a feature of the case upon which they had made no agreement as to what should be told and what kept secret.

"These men are trying to put their crime on me," Don Miguel now said, fury in his tone. "They know that I left Mr. Cameron working at his desk. They were in the corridor and saw me pass down the elevator, which was making its last trip at that moment. They were whispering in a corner, in sight of the door to the Cameron suite. They took advantage of circumstances to place the crime on me."

This was what Nestor was aiming at. The three men, the only ones there that night, so far as he knew, were quarreling with each other. This would help in bringing out the truth. He decided to talk no more on the case for the time being.

"We ought to be looking up the boys," he said, by way of changing the subject.

"It will be daylight very soon now," Lieutenant Gordon replied, "and then something may be done. Rest assured that we shall do all we can to bring them back."
