"Bah! you black parrot!" muttered Maurice scornfully and turned upon his heel. As he vanished down the walk Dido clapped her hands together with great satisfaction and began to sing in low tones. Her song was barbaric in words and strange beyond all telling in the music. It rose and fell, and moaned and drawled, in a curiously painful manner. In the drawing-room Mrs. Dallas had risen to her feet at the first deep contralto note, and now stood rocking herself to and fro with an expression of alarm on her face. Isabella was terrified in her turn by Dido's song and her mother's strange conduct, though by this time she should have been used to these eccentricities.

"Mother, what is it? What does Dido sing?"

Mrs. Dallas, closing her eyes, continued rocking herself to and fro, saying but one word in answer.

"Voodoo!" she said, and that was all. But it was enough for Isabella. She shrieked and ran out of the room. Then Dido, still singing, appeared at the window, and looked at Mrs. Dallas with an expression of triumph.

"Why do you sing the death song?" asked Mrs. Dallas, opening her eyes,

"Because de master hab doomed dat yaller-ha'r," said Dido, and continued her song.

In the meantime Maurice walked slowly homeward, puzzling out in his own mind as to what could be the meaning of these strange things. He could not understand why Mrs. Dallas objected to him as a son-in-law; nor could he surmise the meaning of the mysterious word, "Voodoo," pronounced so significantly by Dido, However, he saw plainly that the negress was the disturbing element in the Dallas household, and by a half-hypnotic control over the weak will of her mistress, she could act as she pleased. The widow had been born and brought up in the Barbadoes. She was a half-educated woman of feeble intellect, and having been left during the time her mind and character were being formed solely to the society of black servants, she had imbibed--not unnaturally--many of the debased superstitions of Africa. Dido knew this, and by means of her claims to a knowledge of Obi, she was enabled to rule Mrs. Dallas, and also, as has been stated, to exercise a powerful influence over the plastic mind of Isabella.

"But I'll spoil her designs in that quarter," muttered Maurice, as his thoughts led him to this conclusion. "Isabella shall not be dragged down to the level of her mother. I shall marry her, and so destroy the influence of that vile negress."

This was easier said than done, as Maurice, simple and upright in conduct and character, was no match for the unscrupulous machinations of Dido. She hated the young man, and was determined that he should not marry her nursling. But whether she had, like Mrs. Dallas, a preference for David over Etwald, Maurice could not determine. The more he thought over affairs, the more incoherent and complicated did they become; so Alymer gave up the task in despair. Then it occurred to him that Mrs. Dallas had referred him to Major Jen; so to his guardian Maurice went the moment he arrived at the big house. But to his surprise, the major was not to be found.

"Major gone out, sir," explained Jaggard, to whom Maurice applied for information. "He got a message from Dr. Etwald, and went to see him. Be back to dinner, sir, I b'lieve."
