Manuel, after pausing for a moment to take his breath, strode up to the group.

"Get in there, some of you!" he ordered, "And show me the way. I want to see over the place."

A chorus of wails arose. The guards shrank and cowered at the suggestion. Their terror was more than panicky, it was even hysterical.

They shook with convulsive jerks of fear, as though they had a spasm disease.

"Christophe!" cried one of them, in a sort of howl. "Christophe! For three days he is here, Yes! We see him walk, Yes! If we go in, he will make us jump off the cliff!"

And another added, with an undertone of superst.i.tious horror,

"And his ghost will be waiting at the bottom to carry our ghosts away!"

"Fools!" declared Manuel, "open the door!"

He pointed to where the huge, rusty iron-bound door frowned in the blank wall of gray stone.

The negro guards hung back and gabbled together, but Manuel turned upon them fiercely with uplifted switch. At that, the giant warder, who had already acknowledged the mastership, slouched forward and pulled open the creaking door, leaving a dark opening from which came the smell of foul air and poisonous vegetation.

Manuel motioned with his head for Stuart to precede him.

The boy hesitated. He was brave enough, but the terror of the negroes was catching. He would not have admitted to being afraid, but there was a lump in his throat and his legs felt unsteady.

The Cuban, who felt sure that Stuart was not the negro horse-boy that he seemed, judged this appearance of fear as evidence that the boy was still playing a part, and turned on him with a snarl.

"Get in there, you!"

s.c.r.e.w.i.n.g up his courage, Stuart stepped forward, though hesitatingly and unwillingly. Just as he crossed the threshold, the giant warder reached out a gaunt hand and pulled him back.

"Not that way!" he said. "Two steps more, Boy, and you are dead!"

Manuel started. From his pocket he took a portable electric light and flashed it upon the ground just within the entrance.

The negro guard was right. Immediately before him lay a deep pit, how deep there was no means of saying. Once it had been covered with a trap-door, which could be worked from the Inner Citadel. Thus Christophe, if he pleased, could send a message of welcome to his visitors, and drop them to a living death with the words of hospitality on his lips.

"If I had gone first," said Manuel quietly, turning to the guards, "not one of you would have said a word!"

The negroes slunk away under his gaze. The accusation was true. They had no love for the "whites." Only the fact that they believed Stuart to be a negro boy had saved him.

The boy looked down at that profound dungeon, from which rose a faint stench, and shuddered.

There was a heavy pause. Manuel was debating whether he dare try and force the guards to show the way. If he ordered it, he would have to force it through, or the prestige he had won would be lost. He dared not. As between the terror of a white man's gun, and the terror of a "ha'nt," the latter was the more powerful.

Motioning Stuart to enter and showing the narrow ledge around the pit with the spotlight, he followed. Then he turned to the guards cl.u.s.tered outside.

"Close the door!" he ordered, curtly.

This command was obeyed with alacrity. The negro guards were only too anxious to see that hole in the wall shut. Suppose the ghost of Christophe should come gliding out among them!

So far, the Cuban was safe. He had reached the Citadel and entered it.

He had no fear that the warders would open it again to spy on him.

Their terror was too real.

Raising the spotlight so that it flashed full upon Stuart's face, the Cuban spoke.

"Understand me, now," he said curtly, and with a hard ring in his voice.

"How much of your story may be true and how much false I have not yet found out. But, if what you say about hating Leborge is true, I will put you in a place where you will be able to see him. You have a pistol, I know. If you see Leborge raise pistol or knife against me, shoot, and shoot quickly! I will make you rich!"

Stuart thought to himself that if the conspirators were to come to quarreling, that was the very time he would keep still. He, certainly, had no desire for bloodshed, nor any intention to fire at anybody, if he could help it. But he only answered,

"I understand."

Manuel's intention was no less concealed. He planned either to reveal the boy to his fellow-conspirators, or else, to reveal him to the negro warders as a white intruder. Either way, he figured, there would be an end to the boy.

By the light of his lamp, consulting a small ma.n.u.script chart of the ruin, Manuel pa.s.sed through many tortuous pa.s.sages and dark chambers until he came to a ruined wall. Climbing a few feet up the crumbling stones, he set his eye to a crevice, nodded as though satisfied, wrenched away several more stones, laying these down silently and beckoned Stuart to come beside him.

The boy looked down on a circular hall, the outer arc of which was pierced with ruined windows opening to the sky.

"Leborge will sit there!" whispered Manuel, pointing. "Kill him, and you will be rich!"

Stuart nodded. He did not trust himself to speak.

Walking as silently as he could, Manuel left the place, pondering in his own mind what he was going to do with the boy. Should he reveal the secret and have his fellow-conspirators kill him? Should he turn him over to the machetes of the negroes? Or should he kill the boy, himself?

One thing he had determined--that Stuart should not reach the plains below, alive.

And Stuart, in that hole of the ruined wall, crouched and watched. Of what was to happen in that room below, what dark plot he was to hear, he had no knowledge. Yet, over his eager desire to find out this conspiracy against the United States, above his anxiety with regard to the fate of his father, one question loomed in ever larger and blacker proportions--

He had got into the Citadel. How was he to get out?

CHAPTER IV

THE GHOST OF CHRISTOPHE

Manuel was no coward. Somewhere, back in his Spanish ancestry, had been a single drop of an Irish strain, adding a certain combativeness to the gallantry of his race. That drop, too, mixed badly with Spanish treachery, and made him doubly dangerous.

Certainly the Cuban was no coward. But, as he came out from the murk of those chambers with their rotting floors, many of them undermined by oubliettes and dungeons, he felt a chill of fear. Even the occasional bursts of sunshine through the cloud-fog which perpetually sweeps over La Ferriere did not hearten him. He pa.s.sed into the open s.p.a.ce back of the outer walls and set himself to climb the long flight of stone steps that led to the battlements, where, he thought, his fellow conspirators might be. But, on the summit, he found himself alone.

The battlements cowed his spirits. With walls fifteen feet thick, wide enough to allow a carriage to be driven upon them, they looked over a sheer drop of two thousand feet. Sinister and forbidding, even the sunlight could not lessen their grimness.

As if in memory of the hundreds of victims who had been bidden jump off those ramparts, merely for Christophe's amus.e.m.e.nt, or who had been hurled, screaming, as penalty for his displeasure, a ruddy moss feeding upon decay, has spread over the stones, and this moss, ever kept damp by the cloud-banks which wreathe the Citadel continually is moistly red, like newly shed blood. In cracks and corners, fungi of poisonous hues adds another touch of wickedness. Manuel shivered with repulsion.

Probably not in all the world, certainly not in the Western Hemisphere, is there a ruin of such historic terror as the Citadel of the Black Emperor on the summit of La Ferriere.[1]

[Footnote 1: This ruin, now, is nominally in territory under the jurisdiction of an American provost-marshal. It is therefore less difficult of access than formerly, but it is still considered unsafe for travelers.]

A gleam of sun revealed the extraordinary impregnability of the place.

The double-walled entrance from the hillside, pierced by but a single gate, could only be battered down by heavy artillery, and no guns powerful enough for such a feat could be brought up the hill. The Inner Citadel, access to which was only by a long flight of steps, is unapproachable from any other point, and a handful of defenders could keep an army at bay.
