d we will run the poor sap down.
Nothing out of the ordinary I should say."

"That is what I thought--at first. Read this--" The big, heavy-set man
pushed another and similar paper across the desk. "This one was
addressed to the Secretary of State."

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 you
