The Chief of the U. S. Secret Service had come for a consultation with the President. And whatever lingering doubts may have stifled his reluctant imagination were dispelled when the figure at the desk opened a drawer.

“Notice this,” he told the Chief as he appeared to search for a paper in the desk. “An electroscope; I put it in here last night. It is discharging. The ray has been on since nine-thirty. No current to electrocute me—just a penetrating ray.”

He returned the paper to the drawer and closed it.

“So that is that,” he said, and picked up a document to which he called the visitor’s attention.

“Just acting,” he explained. “The audience may be critical; we must try to give them a good show! And now give me a report. What are you doing? Has anything else turned up? I am counting on you to stand by and see that that electrician is on his toes at twelve o’clock.”

“Stand by is right,” the Chief agreed; “that’s about all we can do. I have twenty men in and about the grounds—there will be as many more later on. And I know now just how little use we are to you, Del.”

“Your expression!” warned Delamater. “Remember you are talking to the President. Very official and all that.”

“Right! But now tell me what is the game, Del. If that devil fails to knock you out here where you are safe, he will get you when you leave the room.”

“Perhaps,” agreed the pseudo-executive, “and again, perhaps not. He won’t get me here; I am sure of that. They have this part of the room insulated. The phone wire is cut—my conversations there are all faked.

“There is only one spot in this room where that current can pass. A heavy cable is grounded outside in wet earth. It comes to a copper plate on this desk; you can’t see it—it is under those papers.”
