Harry was ready to send a bullet through the man's brain if he attacked Denby Chadwick.
But it became evident that Grady was here for no such purpose. His face was ugly and leering; but it carried no fiendish look.
The men were conversing, but Harry could not catch their words. Chadwick drew forth a small portfolio, and gave it to Grady. The evil-faced man opened it and peered in at the contents.
He spoke a few words to Chadwick; then arose and went to the door.
For a moment Harry thought he was leaving; instead, he reappeared with a waiter. The man had bottles and glasses. Drinks were poured.
Grady, grinning, imbibed deeply. Chadwick, morose, did not touch his glass. This was an opportunity. Harry felt that nothing would occur for several minutes at least. He hurried back to the spot where he had rigged his aerial.
He had removed the sending apparatus about thirty feet from the car. Opening communication, he tapped a code message, telling all that he had observed, and giving his exact location. He received a prompt response. He was to watch what happened, and to wait until the men left; then to follow Grady in preference to Chadwick.
Most important, Harry was to send a quick signal by wireless before he left, leaving the equipment set up, if necessary, to make a hasty departure.
Gauging the distance from the spot to the roadhouse, Harry figured he could make a quick trip back and forth. He tapped word to stand by; that he would signal again within five minutes. Leaving the key, he went back to the Green Mill.
Chadwick and Grady were still at their table. Harry watched them a few minutes.
