prayers. He sat up on the bed, feeling mechanically at the place where
the handle of his sword would have been but two hours since, feeling his
hair stand on end, and a cold sweat began to stream down his face as
the strange fantastic being step by step approached him. At length the
apparition paused, the prisoner and he stood face to face for a moment,
their eyes riveted; then the mysterious stranger spoke in gloomy tones.

"Young man," said he, "you have prayed to the devil for vengeance on the
men who have taken you, for help against the God who has abandoned you.
I have the means, and I am here to proffer it. Have you the courage to
accept?"

"First of all," asked Sainte-Croix; "who are you?"

"Why seek you to know who I am," replied the unknown, "at the very
moment when I come at your call, and bring what you desire?"

"All the same," said Sainte-Croix, still attributing what he heard to a

his enormities were so well accredited that there was no scruple as to
having him arrested. A warrant was out against him: Exili was taken up,
and was lodged in the Bastille. He had been there about six months when
Sainte-Croix was brought to the same place. The prisoners were numerous
just then, so the governor had his new guest put up in the same room as
the old one, mating Exili and Sainte-Croix, not knowing that they were
a pair of demons. Our readers now understand the rest. Sainte-Croix was
put into an unlighted room by the gaoler, and in the dark had failed
to see his companion: he had abandoned himself to his rage, his
imprecations had revealed his state of mind to Exili, who at once seized
the occasion for gaining a devoted and powerful disciple, who once out
