Sergius kept his seat on the bench; but the charm of the glorious prospect spread out before it was gone.

Two points were swimming in his consciousness, like motes in a mist: first, there was a conspiracy afoot; next, the conspiracy was against the daughter of the Prince of India.

When at the door of the old Lavra upon the snow-bound shore of the White Lake, he bade Father Hilarion farewell and received his blessing, and the commission of an Evangel, the idea furthest from him was to signalize his arrival in Constantinople by dropping first thing into love. And to be just, the idea was now as distant from him as ever; yet he had a vision of the child-faced girl he met on the landing at the White Castle in the hands of enemies, and to almost any other person the shrinking it occasioned would have been strange, if not suspicious. His most definite feeling was that something ought to be done in her behalf.

Besides this the young monk had another incentive to action. In the colloquy overheard by him the chief speaker described himself a son of the Hegumen of the St. James'. The St. James'! His own Brotherhood! His own Hegumen! Could a wicked son have been born to that excellent man? Much easier to disbelieve the conspirator; still there were traditions of the appearance of monsters permitted for reasons clear at least to Providence. This might be an instance of the kind. Doubtless the creature carried on its countenance or person evidences of a miracle of evil. In any event there could be no harm in looking at him.

Sergius accordingly arose, and set out in pursuit of the conspirators. Could he overtake the sedan, they were quite certain to be in the vicinity, and he doubted not discovering them.

The steps of the sedan-carriers, peculiarly quick and sliding, seemed in passing the bench to have been going northwardly toward Point Demetrius. Thither he first betook himself.

In the distance, over the heads of persons going and coming, he shortly beheld the top of a chair in motion, and he followed it rapidly, fearing its occupant might quit the wall by the stairs near the stables of the Bucoleon. But when it was borne past that descent he went more leisurely, knowing it must meet him on the return.

Without making the Point, however, the chair was put about toward him. Unable to discover any one so much as suggestive of the plotters, and fearing a mistake, he peered into the front window of the painted box. A woman past the noon of life gave him back in no amiable mood the stare with which he saluted her.

There was but one explanation: he should have gone down the wall southwardly. What was to be done? Give up the chase? No, that would be to desert his little friend. And besides he had not put himself within hearing of the design against her--it was a doing of Providence. He started back on his trace.

The error but deepened his solicitude. What if the victim was then being hurried away?

At the head of the stairway by the stables he paused; as it was deserted, he continued on almost running--on past the cracked bench--past the Cleft Gate. Now, in front, he beheld the towers of the imperial residence bearing the name Julian, and he was upbraiding himself for indecision, and loading his conscience with whatever grief might happen the poor girl, when he beheld a sedan coming toward him. It was very ornate, and in the distance shone with burnishments--it was the chair--hers. By it, on the right hand, strode the gigantic negro who had so astonished him at the White Castle. He drew a long breath, and stopped. They would be bold who in daylight assailed that king of men!

And he was taking note of the fellow's barbaric finery, the solemn stateliness of his air, and the superb indifference he manifested to the stare of passers-by, when a man approached the chair on the opposite side. The curtain of the front window was raised, and through it, Sergius observed the inmate draw hastily away from the stranger, and drop a veil over her face.

Here was one of the parties for whom he was looking. Where was the other? Then the man by the left window looked back over his shoulder as if speaking, and out of the train of persons following the sedan, one stepped briskly forward, joined the intruder, and walked with him long enough to be spoken to, and reply briefly; after which he fell back and disappeared. This answered the inquiry.

Assured now of one of the conspirators in sight, the monk resolved to await the coming up. Through the front window of the carriage, which was truly a marvel of polish and glitter, the girl might recognize him; perhaps she would speak; or possibly the negro might recall him; in either event he would have an excuse for intervention.

Meantime, calmly as he could--for he was young, and warm blooded, and in all respects a good instrument to be carried away by righteous indignation--he took careful note of the stranger, who kept his place as if by warrant, occasionally addressing the shrinking maiden.

Sergius was now more curious than angry; and he cared less to know who the conspirator was than how he looked. His surprise may be imagined when, the subject of investigation having approached near enough to be perfectly observed, instead of a monster marked, like Cain, he appeared a graceful, though undersized person, with an agreeable countenance. The most unfavorable criticism he provoked was the loudness--if the word can be excused--of his dress.

A bright red cloak, hanging in ample folds from an exaggerated buckle of purple enamel on his left shoulder, draped his left side; falling open on the right, it was caught by another buckle just outside the right knee. The arrangement loosed the right arm, but was a serious hamper to walking, and made it inconvenient to get out the rapier, the handle of which was protrusively suggested through the cloak. A tunic of bright orange color, short in sleeve and skirt, covered his body. Where undraped, tight-fitting hose terminating in red shoes, flashed their elongated black and yellow stripes with stunning effect. A red cap, pointed at top, and rolled up behind, but with a long visor-like peak shading the eyes, and a white heron feather slanted in the band, brought the head into negligent harmony with the rest of the costume. The throat and left arm were bare, the latter from halfway above the elbow.

This was the monk's first view of a Byzantine gentleman of the period abroad in full dress to dazzle such of the gentler sex as he might chance to meet.

If Sergius' anticipation had been fulfilled; if, in place of the elegant, rakish-looking chevalier in florid garb, he had been confronted by an individual awry in body or hideous in feature, he would not have been confused, or stood repeating to himself, "My God, can this be a son of the Hegumen?"

That one so holy could have offspring so vicious stupefied him. The young man's sins would find him out--thus it was written--and then, what humiliation, what shame, what misery for the poor father!

Speeding his sympathy thus in advance, Sergius waited until the foremost of the sedan carriers gave him the customary cry of warning. As he stepped aside, two things occurred. The occupant of the box lifted her veil and held out a hand to him. He had barely time to observe the gesture and the countenance more childlike because of the distress it was showing, when the negro appeared on the left side of the carriage. Staying a moment to swing the javelin with which he was armed across the top of the buckler at his back, he leaped forward with the cry of an animal, and caught the gallant, one hand at the shoulder, the other at the knee. The cry and the seizure were parts of the same act. Resistance had been useless had there been no surprise. The Greek had the briefest instant to see the assailant--an instant to look up into the face blacker of the transport of rage back of it, and to cry for help. The mighty hands raised him bodily, and bore him swiftly toward the sea-front of the wall.

There were spectators near by; amongst them some men; but they were held fast by terror. No one moved but Sergius. Having seen the provocation, he alone comprehended the punishment intended.

The few steps to the wall were taken almost on the run. There, in keeping with his savage nature, the negro wished to see his victim fall, but a puff of wind blew the red cloak over his eyes, and he stopped to shake it aside. The Greek in the interval seeing the jagged rocks below, and the waves rolling in and churning themselves into foam, caught at his enemy's head, and the teeth of the gold-gilt iron crown cut his palms, bringing the blood. He writhed, and into Nilo's ears--pitiless if they had not been dead--poured screams for mercy. Then Sergius reached out, and caught him.

Nilo made no resistance. When he could free his eyes from the cloak he looked at the rescuer, who, unaware of his infirmity, was imploring him:

"As thou lovest God, and hopest mercy for thyself, do no murder!"

Now, if not so powerful as Nilo, Sergius was quite as tall; and while they stood looking at each other, their faces a little apart, the contrast between them was many sided. And one might have seen the ferocity of the black visage change first with pleased wonder; then brighten with recognition.

The Byzantine gained his feet quickly, and in his turn taken with a murderous impulse, drew his sword. Nilo, however, was quickest; the point of his javelin was magically promotive of Sergius' renewed efforts to terminate the affair. A great many persons were now present. To bring a multitude in hot assemblage, strife is generally more potential than peace, assume what voice the latter may. These rallied to Sergius' assistance; one brought the defeated youth his hat, fallen in the struggle; others helped him rearrange his dress; and congratulating him that he was alive, they took him in their midst, and carried him away. To have drawn upon such a giant! What a brave spirit the lad must possess!

It pleased Sergius to think he had saved the Byzantine. His next duty was to go to ............
