"Why sigh, Juan, why regret?" cried Madame, immediately. "Old age is only tragic to those who have never been young."

She directed a glance toward him as she spoke those words, and as I had felt when I had seen his tragic face on the veranda that morning I felt again in detecting this look of Madame de Stamer's. The yearning yet selfless love which it expressed was not for my eyes to witness.

"Thank G.o.d, Marie," replied the Colonel, and gallantly kissed his hand to her, "we have both been young, gloriously young."

When, at the termination of this truly historic dinner, the ladies left us:

"Remember, Juan," said Madame, raising her white, jewelled hand, and holding the fingers characteristically curled, "no excitement, no billiards, no cards."

Colonel Menendez bowed deeply, as the invalid wheeled herself from the room, followed by Miss Beverley. My heart was beating delightfully, for in the moment of departure the latter had favoured me with a significant glance, which seemed to say, "I am looking forward to a chat with you presently."

"Ah," said Colonel Menendez, when we three men found ourselves alone, "truly I am blessed in the autumn of my life with such charming companionship. Beauty and wit, youth and discretion. Is he not a happy man who possesses all these?"

"He should be," said Harley, gravely.

The saturnine Pedro entered with some wonderful crusted port, and Colonel Menendez offered cigars.

"I believe you are a pipe-smoker," said our courteous host to Harley, "and if this is so, I know that you will prefer your favourite mixture to any cigar that ever was rolled."

"Many thanks," said Harley, to whom no more delicate compliment could have been paid.

He was indeed an inveterate pipe-smoker, and only rarely did he truly enjoy a cigar, however choice its pedigree. With a sigh of content he began to fill his briar. His mood was more restful, and covertly I watched him studying our host. The night remained very warm and one of the two windows of the dining room, which was the most homely apartment in Cray's Folly, was wide open, offering a prospect of sweeping velvet lawns touched by the magic of the moonlight.

A short silence fell, to be broken by the Colonel.

"Gentlemen," he said, "I trust you do not regret your fishing excursion?"

"I could cheerfully pa.s.s the rest of my days in such ideal surroundings," replied Paul Harley.

I nodded in agreement.

"But," continued my friend, speaking very deliberately, "I have to remember that I am here upon business, and that my professional reputation is perhaps at stake."

He stared very hard at Colonel Menendez.

"I have spoken with your butler, known as Pedro, and with some of the other servants, and have learned all that there is to be learned about the person unknown who gained admittance to the house a month ago, and concerning the wing of a bat, found attached to the door more recently."

"And to what conclusion have you come?" asked Colonel Menendez, eagerly.

He bent forward, resting his elbows upon his knees, a pose which he frequently adopted. He was smoking a cigar, but his total absorption in the topic under discussion was revealed by the fact that from a pocket in his dinner jacket he had taken out a portion of tobacco, had laid it in a slip of rice paper, and was busily rolling one of his eternal cigarettes.

"I might be enabled to come to one," replied Harley, "if you would answer a very simple question."

"What is this question?"

"It is this-Have you any idea who nailed the bat's wing to your door?"

Colonel Menendez's eyes opened very widely, and his face became more aquiline than ever.

"You have heard my story, Mr. Harley," he replied, softly. "If I know the explanation, why do I come to you?"

Paul Harley puffed at his pipe. His expression did not alter in the slightest.

"I merely wondered if your suspicions tended in the direction of Mr.

Colin Camber," he said.

"Colin Camber!"

As the Colonel spoke the name either I became victim of a strange delusion or his face was momentarily convulsed. If my senses served me aright then his p.r.o.nouncing of the words "Colin Camber" occasioned him positive agony. He clutched the arms of his chair, striving, I thought, to retain composure, and in this he succeeded, for when he spoke again his voice was quite normal.

"Have you any particular reason for your remark, Mr. Harley?"

"I have a reason," replied Paul Harley, "but don't misunderstand me. I suggest nothing against Mr. Camber. I should be glad, however, to know if you are acquainted with him?"

"We have never met."

"You possibly know him by repute?"

"I have heard of him, Mr. Harley. But to be perfectly frank, I have little in common with citizens of the United States."

A note of arrogance, which at times crept into his high, thin voice, became perceptible now, and the aristocratic, aquiline face looked very supercilious.

How the conversation would have developed I know not, but at this moment Pedro entered and delivered a message in Spanish to the Colonel, whereupon the latter arose and with very profuse apologies begged permission to leave us for a few moments.

When he had retired:

"I am going upstairs to write a letter, Knox," said Paul Harley. "Carry on with your old duties to-day, your new ones do not commence until to- morrow."

With that he laughed and walked out of the dining room, leaving me wondering whether to be grateful or annoyed. However, it did not take me long to find my way to the drawing room where the two ladies were seated side by side upon a settee, Madame's chair having been wheeled into a corner.

"Ah, Mr. Knox," exclaimed Madame as I entered, "have the others deserted, then?"

"Scarcely deserted, I think. They are merely straggling."

"Absent without leave," murmured Val Beverley.

I laughed, and drew up a chair. Madame de Stamer was smoking, but Miss Beverley was not. Accordingly, I offered her a cigarette, which she accepted, and as I was lighting it with elaborate care, every moment finding a new beauty in her charming face, Pedro again appeared and addressed some remark in Spanish to Madame.

"My chair, Pedro," she said; "I will come at once."

The Spanish butler wheeled the chair across to the settee, and lifting her with an ease which spoke of long practice, placed her amidst the cushions where she spent so many hours of her life.

"I know you will excuse me, dear," she said to Val Beverley, "because I feel sure that Mr. Knox will do his very best to make up for my absence. Presently, I shall be back."

Pedro holding the door open, she went wheeling out, and I found myself alone with Val Beverley.

At the time I was much too delighted to question the circ.u.mstances which had led to this tete-a-tete, but had I cared to give the matter any consideration, it must have presented rather curious features. The call first of host and then of hostess was inconsistent with the courtesy of the master of Cray's Folly, which, like the appointments of his home and his mode of life, was elaborate. But these ideas did not trouble me at the moment.

Suddenly, however, indeed before I had time to speak, the girl started and laid her hand upon my arm.
