He remained in a very evil humour, and now the cause of this suddenly came to light.

"I have spent a thoroughly unpleasant afternoon," he continued, "interviewing an impossible country policeman who had never heard of my existence!"

This display of human resentment honestly delighted me. It was refreshing to know that the omniscient Paul Harley was capable of pique.

"One, Inspector Aylesbury," he went on, bitterly, "a large person bearing a really interesting resemblance to a walrus, but lacking that creature's intelligence. It was not until Superintendent East had spoken to him from Scotland Yard that he ceased to treat me as a suspect. But his new att.i.tude was almost more provoking than the old one. He adopted the manner of a regimental sergeant-major reluctantly interviewing a private with a grievance. If matters should so develop that we are compelled to deal with that fish-faced idiot, G.o.d help us all!"

He burst out laughing, his good humour suddenly quite restored, and taking out his pipe began industriously to load it.

"I can smoke while I am changing," he said, "and you can sit there and tell me all about Colin Camber."

I did as he requested, and Harley, who could change quicker than any man I had ever known, had just finished tying his bow as I completed my story of the encounter at the Lavender Arms.

"Hm," he muttered, as I ceased speaking. "At every turn I realize that without you I should have been lost, Knox. I am afraid I shall have to change your duties to-morrow."

"Change my duties? What do you mean?"

"I warn you that the new ones will be less pleasant than the old! In other words, I must ask you to tear yourself away from Miss Val Beverley for an hour in the morning, and take advantage of Mr. Camber's invitation to call upon him."

"Frankly, I doubt if he would acknowledge me."

"Nevertheless, you have a better excuse than I. In the circ.u.mstances it is most important that we should get in touch with this man."

"Very well," I said, ruefully. "I will do my best. But you don't seriously think, Harley, that the danger comes from there?"

Paul Harley took his dinner jacket from the chair upon which the man had laid it out, and turned to me.

"My dear Knox," he said, "you may remember that I spoke, recently, of retiring from this profession?"

"You did."

"My retirement will not be voluntary, Knox. I shall be kicked out as an incompetent a.s.s; for, respecting the connection, if any, between the narrative of Colonel Menendez, the bat wing nailed to the door of the house, and Mr. Colin Camber, I have not the foggiest notion. In this, at last, I have triumphed over Auguste Dupin. Auguste Dupin never confessed defeat."

CHAPTER X

THE NIGHT WALKER

If luncheon had seemed extravagant, dinner at Cray's Folly proved to be a veritable Roman banquet. To a.s.sociate ideas of selfishness with Miss Beverley was hateful, but the more I learned of the luxurious life of this queer household hidden away in the Surrey Hills the less I wondered at any one's consenting to share such exile. I had hitherto counted an American freak dinner, organized by a lucky plunger and held at the Cafe de Paris, as the last word in extravagant feasting. But I learned now that what was caviare in Monte Carlo was ordinary fare at Cray's Folly.

Colonel Menendez was an epicure with an endless purse. The excellence of one of the courses upon which I had commented led to a curious incident.

"You approve of the efforts of my chef?" said the Colonel.

"He is worthy of his employer," I replied.

Colonel Menendez bowed in his cavalierly fashion and Madame de Stamer positively beamed upon me.

"You shall speak for him," said the Spaniard. "He was with me in Cuba, but has no reputation in London. There are hotels that would snap him up."

I looked at the speaker in surprise.

"Surely he is not leaving you?" I asked.

The Colonel exhibited a momentary embarra.s.sment.

"No, no. No, no," he replied, waving his hand gracefully, "I was only thinking that he-" there was a scarcely perceptible pause-"might wish to better himself. You understand?"

I understood only too well; and recollecting the words spoken by Paul Harley that afternoon, respecting the Colonel's will to live, I became conscious of an uncomfortable sense of chill.

If I had doubted that in so speaking he had been contemplating his own death, the behaviour of Madame de Stamer must have convinced me. Her complexion was slightly but cleverly made up, with all the exquisite art of the Parisienne, but even through the artificial bloom I saw her cheeks blanch. Her face grew haggard and her eyes burned unnaturally. She turned quickly aside to address Paul Harley, but I knew that the significance of this slight episode had not escaped him.

He was by no means at ease. In the first place, he was badly puzzled; in the second place, he was angry. He felt it inc.u.mbent upon him to save this man from a menace which he, Paul Harley, evidently recognized to be real, although to me it appeared wildly chimerical, and the very person upon whose active cooperation he naturally counted not only seemed resigned to his fate, but by deliberate omission of important data added to Harley's difficulties.

How much of this secret drama proceeding in Cray's Folly was appreciated by Val Beverley I could not determine. On this occasion, I remember, she was simply but perfectly dressed and, in my eyes, seemed the most sweetly desirable woman I had ever known. Realizing that I had already revealed my interest in the girl, I was oddly self-conscious, and a hundred times during the progress of dinner I glanced across at Harley, expecting to detect his quizzical smile. He was very stern, however, and seemed more reserved than usual. He was uncertain of his ground, I could see. He resented the understanding which evidently existed between Colonel Menendez and Madame de Stamer, and to which, although his aid had been sought, he was not admitted.

It seemed to me, personally, that an almost palpable shadow lay upon the room. Although, save for this one lapse, our host throughout talked gaily and entertainingly, I was obsessed by a memory of the expression which I had detected upon his face that morning, the expression of a doomed man.

What, in Heaven's name, I asked myself, did it all mean? If ever I saw the fighting spirit looking out of any man's eyes, it looked out of the eyes of Don Juan Sarmiento Menendez. Why, then, did he lie down to the menace of this mysterious Bat Wing, and if he counted opposition futile, why had he summoned Paul Harley to Cray's Folly?

With the pa.s.sing of every moment I sympathized more fully with the perplexity of my friend, and no longer wondered that even his highly specialized faculties had failed to detect an explanation.

Remembering Colin Camber as I had seen him at the Lavender Arms, it was simply impossible to suppose that such a man as Menendez could fear such a man as Camber. True, I had seen the latter at a disadvantage, and I knew well enough that many a genius has been also a drunkard. But although I was prepared to find that Colin Camber possessed genius, I found it hard to believe that this was of a criminal type. That such a character could be the representative of some remote negro society was an idea too grotesque to be entertained for a moment.

I was tempted to believe that his presence in the neighbourhood of this haunted Cuban was one of those strange coincidences which in criminal history have sometimes proved so tragic for their victims.

Madame de Stamer, avoiding the Colonel's glances, which were pathetically apologetic, gradually recovered herself, and:

"My dear," she said to Val Beverley, "you look perfectly sweet to- night. Don't you think she looks perfectly sweet, Mr. Knox?"

Ignoring a look of entreaty from the blue-gray eyes:

"Perfectly," I replied.

"Oh, Mr. Knox," cried the girl, "why do you encourage her? She says embarra.s.sing things like that every time I put on a new dress."

Her reference to a new dress set me speculating again upon the apparent anomaly of her presence at Cray's Folly. That she was not a professional "companion" was clear enough. I a.s.sumed that her father had left her suitably provided for, since she wore such expensively simple gowns. She had a delightful trick of blushing when attention was focussed upon her, and said Madame de Stamer:

"To be able to blush like that I would give my string of pearls-no, half of it."

"My dear Marie," declared Colonel Menendez, "I have seen you blush perfectly."

"No, no," Madame disclaimed the suggestion with one of those Bernhardt gestures, "I blushed my last blush when my second husband introduced me to my first husband's wife."

"Madame!" exclaimed Val Beverley, "how can you say such things?" She turned to me. "Really, Mr. Knox, they are all fables."

"In fables we renew our youth," said Madame.

"Ah," sighed Colonel Menendez; "our youth, our youth."
