He smiled in a way all his own.

“If your business is of a painfully professional nature,” he added, “I must beg you to excuse me for fourteen days, as I am taking a badly needed holiday with my friend.”

“Ah, is it so?” replied the Colonel, placing his hat and cane upon the table, and sitting down rather wearily in a big leathern armchair which Harley had pushed forward. “If I intrude I am sorry, but indeed my business is urgent, and I come to you on the recommendation of my friend, Senor Don Merry del Val, the Spanish Ambassador.”

He raised his eyes to Harley’s face with an expression of peculiar appeal. I rose to depart, but:

“Sit down, Knox,” said Harley, and turned again to the visitor. “Please proceed,” he requested. “Mr. Knox has been with me in some of the most delicate cases which I have ever handled, and you may rely upon his discretion as you may rely upon mine.” He pushed forward a box of cigars. “Will you smoke?”

“Thanks, no,” was the answer; “you see, I rarely smoke anything but my cigarettes.”

Colonel Menendez extracted a slip of rice paper from a little packet which he carried, next, dipping two long, yellow fingers into his coat pocket, he brought out a portion of tobacco, laid it in the paper, and almost in the twinkling of an eye had made, rolled, and lighted a very creditable cigarette. His dexterity was astonishing, and seeing my surprise he raised his heavy eyebrows, and:

“Practice makes perfect, is it not said?” he remarked.

He shrugged his shoulders and dropped the extinguished match in an ash tray, whilst I studied him with increasing interest. Some dread, real or imaginary, was oppressing the man’s mind, I mused. I felt my presence to be unwelcome, but:

“Very well,” he began, suddenly. “I expect, Mr. Harley, that you will be disposed to regard what I have to tell you rather as a symptom of what you call nerves than as evidence of any agency directed against me.”
