“You puzzle me, sir,” said the latter. “Do you wish me to believe that this cult of Voodoo claims European or American devotees?”

“I wish you to believe,” returned the Colonel, “that although as the result of the alarm which I gave the hotel was searched and the Washington police exerted themselves to the utmost, no trace was ever found of the man who had tried to murder me, except”—he extended a long, yellow forefinger, and pointed to the wing of the bat lying upon Harley’s table—“a bat wing was found pinned to my bedroom door.”

Silence fell for a while; an impressive silence. Truly this was the strangest story to which I had ever listened.

“How long ago was that?” asked Harley.

“Only two years ago. At about the time that the great war terminated. I came to Europe and believed that at last I had found security. I lived for a time in London amidst a refreshing peace that was new to me. Then, chancing to hear of a property in Surrey which was available, I leased it for a period of years, installing—is it correct?—my cousin, Madame de Stämer, as housekeeper. Madame, alas, is an invalid, but”—he kissed his fingers—“a genius. She has with her, as companion, a very charming English girl, Miss Val Beverley, the orphaned daughter of a distinguished surgeon of Edinburg. Miss Beverley was with my cousin in the hospital which she established in France during the war. If you will honour me with your presence at Cray’s Folly to-morrow, gentlemen, you will not lack congenial company, I can assure you.”

He raised his heavy eyebrows, looking interrogatively from Harley to myself.

“For my own part,” said my friend, slowly, “I shall be delighted. What do you say, Knox?”

“I also.”

“But,” continued Harley, “your presence here today, Colonel Menendez, suggests to my mind that England has not proved so safe a haven as you had anticipated?”

Colonel Menendez crossed the room and stood once more before the Burmese cabinet, one hand resting upon his hip; a massive yet graceful figure.
