Delamater did not read it at once. He held both papers to the light; his fingers touched the edges only. "No watermark," he mused; "ordinary white writing stock--sold in all the five and ten cent stores. Tried these for fingerprints I suppose?". "Read it," suggested the Chief. "Another picture of an eye," said Delamater aloud, and read: "'Warning. You are dealing with an emissary from a foreign power who is an unfriend of my country. See him no more. This is the first and last warning. The Eye of Allah watches.' "And what is this below--? 'He did not care for your cigars, Mr. Secretary. Next time--but there must be no next time.'" * * * * * Delamater read slowly--lazily. He seemed only slightly interested except when he came to the odd conclusion of the note. But the Chief knew Delamater and knew how that slow indolence could give place to a feverish, alert concentration when work was to be done. "Crazy as a loon," was the man's conclusion as he dropped the papers upon the desk. "Crazy," his chief corrected, "like a fox! Read the last line again; then get this-- "The Secretary of State _is_ meeting with a foreign agent who is here very much incog. Came in as a servant of a real ambassador. Slipped quietly into Washington, and not a soul knew he was here. He met the Secretary in a closed room; no one saw him come or leave--"; "Well, the Secretary tells me that in that room where nobody could see he offered this man a cigar. His visitor took it, tried to smoke it, apologized--and lit one of his own vile cigarettes." "Hm-m!" Delamater sat a little straighter in his chair; his eyebrows were raised now in questioning astonishment. "Dictaphone? Some employee of the Department listening in?" "Impossible." "Now that begins to be interesting," the other conceded. His eyes had lost their sleepy look. "Want me to take it on?" "Later. Right now. I want you to take this visiting gentleman under your personal charge. Here is the name and the room and hotel where he is staying. He is to meet with the Secretary to-night--he knows where. You will get to him unobserved--absolutely unseen; I can leave that to you. Take him yourself to his appointment, and take him without a brass band. But have what men you want tail you and watch out for spies.... Then, when he is through, bring him back and deliver him safely to his room. Compray?" "Right--give me Wilkins and Smeed. I rather think I can get this bird there and back without being seen, but perhaps they may catch Allah keeping tabs on us at that." He laughed amusedly as he took the paper with the name and address. * * * * * A waiter with pencil and order-pad might have been seen some hours later going as if from the kitchen to the ninth floor of a Washington hotel. And the same waiter, a few minutes later, was escorting a guest from a rear service-door to an inconspicuous car parked nearby. The waiter slipped behind the wheel.
