"It is an agreeable sensation, your Highness?"

The boy nodded.

"It is well with your Highness?"

"Very well."

Heiligenstern began a loud rhythmic chant, and gradually the air darkened, but with the mild dimness of a summer twilight, through which sparks could be seen flickering like fire-flies about the reclining prince. The hush grew deeper; but in the stillness Odo became aware of some unseen influence that seemed to envelope him in waves of exquisite sensation. It was as though the vast silence of the night had poured into the room and, like a dark tepid sea, was lapping about his body and rising to his lips. His thoughts, dissolved into emotion, seemed to waver and float on the stillness like sea-weed on the lift of the tide. He stood spell-bound, lulled, yielding himself to a blissful dissolution.

Suddenly he became aware that the hush was too intense, too complete; and a moment later, as though stretched to the cracking-point, it burst terrifically into sound. A huge uproar shook the room, crashing through it like a tangible mass. The sparks whirled in a menacing dance round the little prince's body, and, abruptly blotted, left a deeper darkness, in which the confused herding movements of startled figures were indistinguishably merged. A flash of silence followed; then the liberated forces of the night broke in rain and thunder on the rocking walls of the room.

"Light—light!" some one stammered; and at the same moment a door was flung open, admitting a burst of candle-light and a group of figures in ecclesiastical dress, against which the white gown and black hood of Father Ignazio detached themselves. The Dominican stepped toward the Duke.

"Your Highness," said he in a tone of quiet resolution, "must pardon this interruption; I act at the bidding of the Holy Office."

Even in that moment of profound disarray the name sent a deeper shudder through his hearers. The Duke, who stood grasping the arms of his chair, raised his head and tried to stare down the intruders; but no one heeded his look. At a signal from the Dominican a servant had brought in a pair of candelabra, and in their commonplace light the cabalistic hangings, the magician's appliances and his fantastically-dressed attendants looked as tawdry as the paraphernalia of a village quack. Heiligenstern alone survived the test. Erect, at bay as it were, his black robe falling in hieratic folds, the white wand raised in his hands, he might have personified the Prince of Darkness drawn up undaunted against the hosts of the Lord. Some one had snatched the little prince from his stretcher, and Maria Clementina, holding him to her breast, sat palely confronting the sorcerer. She alone seemed to measure her strength against his in some mysterious conflict of the will. But meanwhile the Duke had regained his voice.

"My father," said he, "on what information does the Holy Office act?"
