"Yes," agreed Harry. "It was put in here by Duncan and myself the night we first came to the cottage. It was part of the equipment."
He threw a thankful glance at Weston. Harry had caught himself just in time. Had he finished his sentence by saying "the night that Duncan disappeared," he would have revealed the fact that The Shadow had paid a mysterious visit to the cottage.
Bruce Duncan had described his adventure to Harry and Weston, during the rational moments that he had had. They realized the part that The Shadow must have played, and the wireless message the next day had explained why the new instrument had been added to the wireless set.
A reply came to Harry's message.
"Same instructions," announced the young man. "Let matters rest to-night. The fact that Cooper does not appear will not change matters in the least. The big event will be to-morrow night. Chefano must remain there to meet the agent of Prince Samanov."
"But when will that man arrive?" asked Cooper.
"We don't know. Possibly in advance of midnight. We are to receive our final orders to-morrow afternoon."
The three men drove to a town on the other side of the mountains for dinner. Harry advised against going to Culbertville. After they had made their trip, he urged his companions to remain in the new town during the evening. As a result, they did not get back to the cottage until after midnight.
"Well, that's over," said Harry as they entered the house. "I'm glad we were away from here at midnight. I was afraid one of you might have become venturesome — as we presume Duncan did."
"Poor Duncan," said Major Weston. "If he did fall into the trap, Chefano probably supposed that it was I. He may have been the fifth man that died."
