Colonel Menendez seemed somewhat taken aback by this direct question.

"I cannot believe it," he confessed.

"Do you believe that this order or religion of Voodooism has any existence outside those places where African negroes or descendents of negroes are settled?"

"I should not have been prepared to believe it, Mr. Harley, prior to my experiences in Washington and elsewhere."

"Then you do believe that there are representatives of this cult to be met with in Europe and America?"

"I should have been prepared to believe it possible in America, for in America there are many negroes, but in England--"

Again he shrugged his shoulders.

"I would remind you," said Harley, quietly, "that there are also quite a number of negroes in England. If you seriously believe Voodoo to follow negro migration, I can see no objection to a.s.suming it to be a universal cult."

"Such an idea is incredible."

"Yet by what other hypothesis," asked Harley, "are we to cover the facts of your own case as stated by yourself? Now," he consulted his pencilled notes, "there is another point. I gather that these African sorcerers rely largely upon what I may term intimidation. In other words, they claim the power of wishing an enemy to death."

He raised his eyes and stared grimly at the Colonel.

"I should not like to suppose that a man of your courage and culture could subscribe to such a belief."

"I do not, sir," declared the Colonel, warmly. "No Obeah man could ever exercise his will upon me!"

"Yet, if I may say so," murmured Harley, "your will to live seems to have become somewhat weakened."

"What do you mean?"

Colonel Menendez stood up, his delicate nostrils dilated. He glared angrily at Harley.

"I mean that I perceive a certain resignation in your manner of which I do not approve."

"You do not approve?" said Colonel Menendez, softly; and I thought as he stood looking down upon my friend that I had rarely seen a more formidable figure.

Paul Harley had roused him unaccountably, and knowing my friend for a master of tact I knew also that this had been deliberate, although I could not even dimly perceive his object.

"I occupy the position of a specialist," Harley continued, "and you occupy that of my patient. Now, you cannot disguise from me that your mental opposition to this danger which threatens has become slackened. Allow me to remind you that the strongest defence is counter-attack. You are angry, Colonel Menendez, but I would rather see you angry than apathetic. To come to my last point. You spoke of a neighbour in terms which led me to suppose that you suspected him of some a.s.sociation with your enemies. May I ask for the name of this person?"

Colonel Menendez sat down again, puffing furiously at his cigarette, whilst beginning to roll another. He was much disturbed, was fighting to regain mastery of himself.

"I apologize from the bottom of my heart," he said, "for a breach of good behaviour which really was unforgivable. I was angry when I should have been grateful. Much that you have said is true. Because it is true, I despise myself."

He flashed a glance at Paul Harley.

"Awake," he continued, "I care for no man breathing, black or white; but asleep"-he shrugged his shoulders. "It is in sleep that these dealers in unclean things obtain their advantage."

"You excite my curiosity," declared Harley.

"Listen," Colonel Menendez bent forward, resting his elbows upon his knees. Between the yellow fingers of his left hand he held the newly completed cigarette whilst he continued to puff vigorously at the old one. "You recollect my speaking of the death of a certain native girl?"

Paul Harley nodded.

"The real cause of her death was never known, but I obtained evidence to show that on the night after the wing of a bat had been attached to her hut, she wandered out in her sleep and visited the Black Belt. Can you doubt that someone was calling her?"

"Calling her?"

"Mr. Harley, she was obeying the call of M'kombo!"

"The call of M'kombo? You refer to some kind of hypnotic suggestions?"

"I ill.u.s.trate," replied the Colonel, "to help to make clear something which I have to tell you. On the night when last the moon was full-on the night after someone had entered the house-I had retired early to bed. Suddenly I awoke, feeling very cold. I awoke, I say, and where do you suppose I found myself?"

"I am all anxiety to hear."

"On the point of entering the Tudor garden-you call it Tudor garden?- which is visible from the window of your room!"

"Most extraordinary," murmured Harley; "and you were in your night attire?"

"I was."

"And what had awakened you?"

"An accident. I believe a lucky accident. I had cut my bare foot upon the gravel and the pain awakened me."

"You had no recollection of any dream which had prompted you to go down into the garden?"

"None whatever."

"Does your room face in that direction?"

"It does not. It faces the lake on the south of the house. I had descended to a side door, unbarred it, and walked entirely around the east wing before I awakened."

"Your room faces the lake," murmured Harley.

"Yes."

Their glances met, and in Paul Harley's expression there seemed to be a challenge.

"You have not yet told me," said he, "the name of your neighbour."

Colonel Menendez lighted his new cigarette.

"Mr. Harley," he confessed, "I regret that I ever referred to this suspicion of mine. Indeed it is hardly a suspicion, it is what I may call a desperate doubt. Do you say that, a desperate doubt?"

"I think I follow you," said Harley.

"The fact is this, I only know of one person within ten miles of Cray's Folly who has ever visited Cuba."

"Ah."

"I have no other sc.r.a.p of evidence to a.s.sociate him I with my shadowy enemy. This being so, you will pardon me if I ask you to forget that I ever referred to his existence."
