“Colonel Juan Menendez,” he read aloud, “Cavendish Club,” and glanced reflectively at Innes. “Do we know the Colonel?” “I think not,” answered Innes; “the name is unfamiliar to me.” “I wonder,” murmured Harley. He glanced across at me. “It’s an awful nuisance, Knox, but just as I thought the decks were clear. Is it something really interesting, or does he want a woman watched? However, his name sounds piquant, so perhaps I had better see him. Ask him to come in, Miss Smith.” Innes and Miss Smith retiring, there presently entered a man of most striking and unusual presence. In the first place, Colonel Menendez must have stood fully six feet in his boots, and he carried himself like a grandee of the golden days of Spain. His complexion was extraordinarily dusky, whilst his hair, which was close cropped, was iron gray. His heavy eyebrows and curling moustache with its little points were equally black, so that his large teeth gleamed very fiercely when he smiled. His eyes were large, dark, and brilliant, and although he wore an admirably cut tweed suit, for some reason I pictured him as habitually wearing riding kit. Indeed I almost seemed to hear the jingle of his spurs. He carried an ebony cane for which I mentally substituted a crop, and his black derby hat I thought hardly as suitable as a sombrero. His age might have been anything between fifty and fifty-five. Standing in the doorway he bowed, and if his smile was Mephistophelean, there was much about Colonel Juan Menendez which commanded respect. “Mr. Harley,” he began, and his high, thin voice afforded yet another surprise, “I feel somewhat ill at ease to--how do you say it?--appropriate your time, as I am by no means sure that what I have to say justifies my doing so.” He spoke most fluent, indeed florid, English. But his sentences at times were oddly constructed; yet, save for a faint accent, and his frequent interpolation of such expressions as “how do you say?”--a sort of nervous mannerism--one might have supposed him to be a Britisher who had lived much abroad. I formed the opinion that he had read extensively, and this, as I learned later, was indeed the case. “Sit down, Colonel Menendez,” said Harley with quiet geniality. “Officially, my working day is ended, I admit, but if you have no objection to the presence of my friend, Mr. Knox, I shall be most happy to chat with you.” 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.”
