The marquis quickly made himself at home, and vied with his host in his eagerness to take the Donna Velvetina down to supper.

The Duc's face darkened visibly in proportion as that of his guest beamed; and to those who looked on, it was evident that a scene was imminent.

At length, when for the nineteenth time the lady accepted the arm of the gallant marquis, the Duc ground his teeth, and stepping up to his rival, pulled his nose.

The marquis in return flung the Duc the entire length of the apartments, and with folded arms calmly awaited the result.

"We fight, Monsieur le Marquis," ground out the smarting Duc.

"Rather!" replied the marquis, with a proud smile.

Sub-Chapter VIII.

THE DUEL.

It was a tragic end in that night's gay scene.

Guests whose carriages were not ordered till 4 a.m. stood shivering in the hall at 11 p.m.

Five hours to wait!

Meanwhile, on two special steamers the Duc de Septimominorelli and the Marquis de Smellismelli sought the sh.o.r.e of France.

On the lonely sands between Calais and Ushant the rivals stood face to face, at a hundred paces distance.

They had no seconds, so each loaded the other's weapon.

It could not have been the wind that made their knees tremble and their teeth chatter, for there was none. Neither could it have been the weight of the pistols which made their hands wave to and fro, for these were Boxer's eight-ounce Maxim Repeaters.

No; these two men were the subjects of deep physical emotion. The moment had come, and the Duc was about to drop his handkerchief, when the Marquis abruptly folded his arms and said, "Excuse me, we have met before, have we not? Ha, ha, Sep, my boy!"

At the sound of his voice, the so-called Duc flung his weapon two hundred yards in the air, and with the bound of a hunted tiger buried himself in the turmoil of the French capital.

There was no duel on those yellow sands after all.

Sub-Chapter IX.

AFTERWARDS.

The mysterious disappearance of the dazzling Duc de Septimominorelli created a profound impression throughout civilised Europe. The Donna Velvetina Peeleretta was inconsolable.

After a while she, too, went abroad.

Sub-Chapter X.

THE SLEUTH-HOUND AGAIN.

Many, many years flew past.

Solomon Smellie's youngest son had been twice Lord Mayor of London, and all London had forgotten the Duc de Septimominorelli and the peerless Donna Velvetina Peeleretta.

All? No, there was one exception.

An aged man in a back room of the Mansion House sometimes produced a plaster cast from the recesses of his pocket, and muttered to himself--

"A time will come--aha!"

Sub-Chapter XI.

THE DESERT JOURNEY.

A lonely traveller traversed the sandy desert wastes of Central Africa.

He was ill-accoutred for so trying a journey, having only a cane to protect himself from the wild beasts, and patent-leather shoes on his feet. No one knew his name; and what made him more mysterious was that, although he spoke English, he paid for everything in Spanish doubloons half a century old!

What could his errand be, amid the typhoons and siroccos of that desolate continent?

For six weeks he had not moistened his parched lips with so much as a drop of water! And his only food had been dried elephant!

Yet he kept his eyes fixed on the mountain range twelve hundred leagues ahead of him; and as each day brought him fifty miles nearer (for he was evidently a practised walker), he murmured to himself, "I come, Velvetina!" and thought nothing of the fatigue.

The man's shoes were unequal to his spirit, and within a hundred miles of his goal he sunk crippled to the ground. The blinding sand swept over him in mountains, and the tropical sun made the end of the cane he carried red-hot.

Any other man in such a condition would have succ.u.mbed. Not so our mysterious traveller.

If he could not walk, he could roll. And he rolled.

Sub-Chapter XII.

THREE CLOUDS ON THE HORIZON.

On the summit of the topmost of those gigantic mountains, the peak of which is lost high in the depths of the cloudless sky, a female stands, and gazes southward.

Her fair form is mysteriously draped in white, and the parasol with which she shuts out the scorching sun from her face effectually conceals her features.

"He cometh--he cometh not," says she, weeping.

At length, in the remote horizon of the limitless desert, there arises a little cloud of dust.

Is it a panther seeking its prey? or a newspaper buffeted by the wind?

or the mirage of the desert?

It is the revolving form of a rolling body; and as she discovers it she trembles like an aspen leaf.

"He comes," mutters she.

Another cloud of dust; not in the south, but in the east.

Can it be an optical delusion, or another revolving figure? Ever and anon the sun gleams on something bright, which looks like the end of a cane.
