"Wait!" said Robert Delamater, sharply. If ever his sleepy indolence had misled his Chief, there was none to do so now in the voice that rang like cold steel. His eyes were slits under the deep-drawn brows, and his mouth was one straight line. * * * * * To the hunter there is no greater game than man. And Robert Delamater, man-hunter, had his treacherous quarry in sight. He fired staccato questions at his Chief. "Is the President at his desk at twelve?" "Yes." "Does he know--about this?" "Yes." "Does he know it means death?" The Chief nodded. "I see a way--a chance," said the operative. "Do I get a free hand?" "Yes--Good Lord, yes! If there's any chance of--" Delamater silenced him. "I'll be the one to take the chance," he said grimly. "Chief, I intend to impersonate the President." "Now listen-- The President and I are about the same build. I know a man who can take care of the make-up; he will get me by anything but a close inspection. This Eye of Allah, up to now, has worked only in the light. We'll have to gamble on that and work our change in the dark. "The President must go to bed as usual--impress upon him that he may be under constant surveillance. Then, in the night, he leaves-- "Oh, I know he won't want to hide himself, but he must. That's up to you. "Arrange for me to go to his room before daylight. From that minute on I am the President. Get me his routine for that morning; I must follow it so as to arouse no least suspicion." * * * * * "But I don't see--" began the Chief. "You will impersonate him--yes--but what then? You will be killed if this maniac makes good. Is the President of the United States to be a fugitive? Is--" "Hold on, hold on!" said Delamater. He leaned back in his chair; his face relaxed to a smile, then a laugh. "I've got it all now. Perhaps it will work. If not--" A shrug of the shoulders completed the thought. "And I have been shooting it to you pretty fast haven't I! Now here is the idea-- "I must be in the President's chair at noon. This Allah person will be watching in, so I must be acting the part all morning. I will have the heaviest insulation I can get under the rug, and I'll have something to take the shot instead of myself. And perhaps, perhaps I will send a message back to the Eye of Allah that will be a surprise. "Is it a bet?" he asked. "Remember, I'm taking the chance--unless you know some better way--" The Chief's chair came down with a bang. "We'll gamble on it, Del," he said; "we've got to--there is no other way.... And now what do you want?" "A note to the White House electrician," said Robert Delamater, "and full authority to ask for anything I may need, from the U. S. Treasury down to a pair of wire-cutters." His smile had become contagious; the Chief's anxious look relaxed. "If you pull this off, Del, they may give you the Treasury or the Mint at that. But remember, republics are notoriously ungenerous."
