"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 Stamer, 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 a.s.sure 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 antic.i.p.ated?"

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

"Mr. Harley," he replied, "four days ago my butler, who is a Spaniard, brought me-" He pointed to the bat wing lying upon the blotting pad. "He had found it pinned to an oaken panel of the main entrance door."

"Was it prior to this discovery, or after it," asked Harley, "that you detected the presence of someone lurking in the neighbourhood of the house?"

"Before it."

"And the burglarious entrance?"

"That took place rather less than a month ago. On the eve of the full moon."

Paul Harley stood up and relighted his pipe.

"There are quite a number of other details, Colonel," he said, "which I shall require you to place in my possession. Since I have determined to visit Cray's Folly, these can wait until my arrival. I particularly refer to a remark concerning a neighbour of yours in Surrey."

Colonel Menendez nodded, twirling his cigarette between his long, yellow fingers.

"It is a delicate matter, gentlemen," he confessed.

"I must take time to consider how I shall place it before you. But I may count upon your arrival tomorrow?"

"Certainly. I am looking forward to the visit with keen interest."

"It is important," declared our visitor; "for on Wednesday is the full moon, and the full moon is in some way a.s.sociated with the sacrificial rites of Voodoo."

CHAPTER III

THE VAMPIRE BAT

An hour had elapsed since the departure of our visitor, and Paul Harley and I sat in the cosy, book-lined study discussing the strange story which had been related to us. Harley, who had a friend attached to the Spanish Emba.s.sy, had succeeded in getting in touch with him at his chambers, and had obtained some few particulars of interest concerning Colonel Don Juan Sarmiento Menendez, for such were the full names and t.i.tles of our late caller.

He was apparently the last representative of a once great Spanish family, established for many generations in Cuba. His wealth was incalculable, although the value of his numerous estates had depreciated in recent years. His family had produced many men of subtle intellect and powerful administrative qualities; but allied to this they had all possessed traits of cruelty and debauchery which at one time had made the name of Menendez a by-word in the West Indies. That there were many people in that part of the world who would gladly have a.s.sa.s.sinated the Colonel, Paul Harley's informant did not deny. But although this information somewhat enlarged our knowledge of my friend's newest client, it threw no fresh light upon that side of his story which related to Voodoo and the extraordinary bat wing episodes.

"Of course," said Harley, after a long silence, "there is one possibility of which we must not lose sight."

"What possibility is that?" I asked.

"That Menendez may be mad. Remorse for crimes of cruelty committed in his youth, and beyond doubt he has been guilty of many, may have led to a sort of obsession. I have known such cases."

"That was my first impression," I confessed, "but it faded somewhat as the Colonel's story proceeded. I don't think any such explanation would cover the facts."

"Neither do I," agreed my friend; "but it is distinctly possible that such an obsession exists, and that someone is deliberately playing upon it for his own ends."

"You mean that someone who knows of these episodes in the earlier life of Menendez is employing them now for a secret purpose of his own?"

"Exactly."

"It renders the case none the less interesting."

"I quite agree, Knox. With you, I believe, that even if the Colonel is not quite sane, at the same time his fears are by no means imaginary."

He gingerly took up the bat wing from the arm of his chair where he had placed it after a detailed examination.

"It seems to be pretty certain," he said, "that this thing is the wing of a Desmodus or Vampire Bat. Now, according to our authority"-he touched a work which lay open on the other arm of his chair-"these are natives of tropical America, therefore the presence of a living vampire bat in Surrey is not to be antic.i.p.ated. I am personally satisfied, however, that this unpleasant fragment has been preserved in some way."

"You mean that it is part of a specimen from someone's collection?"

"Quite possibly. But even a collection of such bats would be quite a novelty. I don't know that I can recollect one outside the Museums. To follow this bat wing business further: there was one very curious point in the Colonel's narrative. You recollect his reference to a native girl who had betrayed certain information to the manager of the estate?"

I nodded rapidly.

"A bat wing was affixed to the wall of her hut and she died, according to our informant, of a lingering sickness. Now this lingering sickness might have been anaemia, and anaemia may be induced, either in man or beast, by frequent but unsuspected visits of a Vampire Bat."

"Good heavens, Harley!" I exclaimed, "what a horrible idea."

"It is a horrible idea, but in countries infested by these creatures such things happen occasionally. I distinctly recollect a story which I once heard, of a little girl in some district of tropical America falling into such a decline, from which she was only rescued in the nick of time by the discovery that one of these Vampire Bats, a particularly large one, had formed the habit of flying into her room at night and attaching itself to her bare arm which lay outside the coverlet."

"How did it penetrate the mosquito curtains?" I enquired, incredulously.

"The very point, Knox, which led to the discovery of the truth. The thing, exhibiting a sort of uncanny intelligence, used to work its way up under the edge of the netting. This disturbance of the curtains was noticed on several occasions by the nurse who occupied an adjoining room, and finally led to the detection of the bat!"

"But surely," I said, "such a visitation would awaken any sleeper?"

"On the contrary, it induces deeper sleep. But I have not yet come to my point, Knox. The vengeance of the High Priest of Voodoo, who figured in the Colonel's narrative, was characteristic in the case of the native woman, since her symptoms at least simulated those which would result from the visits of a Vampire Bat, although of course they may have been due to a slow poison. But you will not have failed to note that the several attacks upon the Colonel personally were made with more ordinary weapons. On two occasions at least a rifle was employed."

"Yes," I replied, slowly. "You are wondering why the lingering sickness did not visit him?"

"I am, Knox. I can only suppose that he proved to be immune. You recall his statement that he made an almost miraculous recovery from the fever which attacked him after his visit to the Black Belt? This would seem to point to the fact that he possesses that rare type of const.i.tution which almost defies organisms deadly to ordinary men."

"I see. Hence the dagger and the rifle?"

"So it would appear."

"But, Harley," I cried, "what appalling crime can the man have committed to call down upon his head a vengeance which has survived for so many years?"

Paul Harley shrugged his shoulders in a whimsical imitation of the Spaniard.

"I doubt if the feud dates any earlier," he replied, "than the time of Menendez's last return to Cuba. On that occasion he evidently killed the High Priest of Voodoo."
