next thing will be, of course, you'll follow them up on these clues in England and arrest them?"

The Commissary shrugged his shoulders. "Arrest them!" he exclaimed, much amused. "Ah, monsieur, but you are sanguine! No officer of justice has ever succeeded in arresting le Colonel Caoutchouc, as we call him in French. He is as slippery as an eel, that man. He wriggles through our fingers. Suppose even we caught him, what could we prove? I ask you. Nobody who has seen him once can ever swear to him again in his next impersonation. He is impayable, this good Colonel. On the day when I arrest him, I assure you, monsieur, I shall consider myself the smartest police-officer in Europe."

"Well, I shall catch him yet," Sir Charles answered, and relapsed into silence.

THE EPISODE OF THE DIAMOND LINKS

"Let us take a trip to Switzerland," said Lady Vandrift. And any one who knows Amelia will not be surprised to learn that we did take a trip to Switzerland accordingly. Nobody can drive Sir Charles, except his wife. And nobody at all can drive Amelia.

There were difficulties at the outset, because we had not ordered rooms at the hotels beforehand, and it was well on in the season; but they were overcome at last by the usual application of a golden key; and we found ourselves in due time pleasantly quartered in Lucerne, at that most comfortable of European hostelries, the Schweitzerhof.

We were a square party of four—Sir Charles and Amelia, myself and Isabel. We had nice big rooms, on the first floor, overlooking the lake; and as none of us was possessed with the faintest symptom of that incipient mania which shows itself in the form of an insane desire to climb mountain heights of disagreeable steepness and unnecessary snowiness, I will venture to assert we all enjoyed ourselves. We spent most of our time sensibly in lounging about the lake on the jolly little steamers; and when we did a mountain climb, it was on the Rigi or Pilatus—where an engine undertook all the muscular work for us.

As usual, at the hotel, a great many miscellaneous people showed a burning desire to be specially nice to us. If you wish to see how friendly and charming humanity is, just try being a well-known millionaire for a week, and you'll learn a thing or two. Wherever Sir Charles goes he is surrounded by charming and disinterested people, all eager to make his distinguished acquaintance, and all familiar with several excellent investments, or several deserving objects of Christian charity. It is my business in life, as his brother-in-law and secretary, to decline with thanks the excellent investments, and to throw judicious cold water on the objects of charity. Even I myself, as the great man's almoner, am very much sought after. People casually allude before me to artless stories of "poor curates in Cumberland, you know, Mr. Wentworth," or widows in Cornwall, penniless poets with epics in their desks, and young painters who need but the breath of a patron to open to them the doors of an admiring Academy. I smile and look wise, while I administer cold water in minute doses; but I never report one of these cases to Sir Charles, except in the rare or almost unheard-of event where I think there is really something in them.

Ever since our little adventure with the Seer at Nice, Sir Charles, who is constitutionally cautious, had been even more careful than usual about possible sharpers. And, as chance would have it, there sat just opposite us at table d'hôte at the Schweitzerhof—'tis a fad of Amelia's to dine at table d'hôte; she says she can't bear to be boxed up all day in private rooms with "too much family"—a sinister-looking man with dark hair and eyes, conspicuous by his bushy overhanging eyebrows. My attention was first called to the eyebrows in question by a nice little parson who sat at our side, and who observed that they were made up of certain large and bristly hairs, which (he told us) had been traced by Darwin to our monkey ancestors. Very pleasant little fellow, this fresh-faced young parson, on his honeymoon tour with a nice wee wife, a bonnie Scotch lassie with a charming accent.

I looked at the eyebrows close. Then a sudden thought struck me. "Do you believe they're his own?" I asked of the curate; "or are they only stuck on—a make-up disguise? They really almost look like it."

"You don't suppose—" Charles began, and checked himself suddenly.

"Yes, I do," I answered; "the Seer!" Then I recollected my blunder, and looked down sheepishly. For, to say the truth, Vandrift had straightly enjoined on me long before to say nothing of our painful little episode at Nice to Amelia; he was afraid if she once heard of it, he would hear of it for ever after.

"What Seer?" the little parson inquired, with parsonical curiosity.

I noticed the man with the overhanging eyebrows give a queer sort of start. Charles's glance was fixed upon me. I hardly knew what to answer.

"Oh, a man who was at Nice with us last year," I stammered out, trying hard to look unconcerned. "A fellow they talked about, that's all." And I turned the subject.

But the curate, like a donkey, wouldn't let me turn it.

"Had he eyebrows like that?" he inquired, in an undertone. I was really angry. If this was Colonel Clay, the curate was obviously giving him the cue, and making it much more difficult for us to catch him, now we might possibly have lighted on the chance of doing so.

"No, he hadn't," I answered testily; "it was a passing expression. But this is not the man. I was mistaken, no doubt." And I nudged him gently.

The little curate was too innocent for anything. "Oh, I see," he replied, nodding hard and looking wise. Then he turned to his wife and made an obvious face, which the man with the eyebrows couldn't fail to notice.

Fortunately, a political discussion going on a few places farther down the table spread up to us and diverted attention for a moment. The magical name of Gladstone saved us. Sir Charles flared up. I was truly pleased, for I could see Amelia was boiling over with curiosity by this time.

After dinner, in the billiard-room, however, the man with the big eyebrows sidled up and began to talk to me. If he was Colonel Clay, it was evident he bore us no grudge at all for the five thousand pounds he had done us out of. On the contrary, he seemed quite prepared to do us out of five thousand more when opportunity offered; for he introduced himself at once as Dr. Hector Macpherson, the exclusive grantee of extensive concessions from the Brazilian Government on the Upper Amazons. He dived into conversation with me at once as to the splendid mineral resources of his Brazilian estate—the silver, the platinum, the actual rubies, the possible diamonds. I listened and smiled; I knew what was coming. All he needed to develop this magnificent concession was a little more capital. It was sad to see thousands of pounds' worth of platinum and car-loads of rubies just crumbling in the soil or carried away by the river, for want of a few hundreds to work them with properly. If he knew of anybody, now, with money to invest, he could recommend him—nay, offer him—a unique opportunity of earning, say, 40 per cent on his capital, on unimpeachable security.

"I wouldn't do it for every man," Dr. Hector Macpherson remarked, drawing himself up; "but if I took a fancy to a fellow who had command of ready cash, I might choose to put him in the way of feathering his nest with unexampled rapidity."

"Exceedingly disinterested of you," I answered drily, fixing my eyes on his eyebrows.

The little curate, meanwhile, was playing billiards with Sir Charles. His glance followed mine as it rested for a moment on the monkey-like hairs.

"False, obviously false," he remarked with his lips; and I'm bound to confess I never saw any man speak so well by movement alone; you could follow every word though
