"Well, Sibyl, what awful revelation does that tiny note contain, to alarm you so?" he asked, in surprise.
"Guy," she said, impatiently, starting up. "I must visit the island to-day."
"The island! Nonsense, Sibyl!" broke in Mrs. Brantwell.
"I must—I must! My business there will not admit of delay. I must go."
"Why, what's wrong? They seemed all well when I left," said her brother, still more surprised.
Feeling it would not do to excite a curiosity she could not satisfy, Sibyl controlled her emotions, and said, more calmly:
"They are well enough. It is not that; but circumstances render it necessary that I should go there to-day. Who will take me over?"
"If you wait for an hour or two, Carl Henley will be here. I heard Mrs. Tom saying he would visit N—— to-night, for things she wanted. If you must go, he will take you when he returns."
"Very well; I suppose that must do," said Sibyl, controlling her burning impatience by a great effort, as she hastily left the room.
And Captain Campbell, having made his adieus, also departed, followed by Mrs. Brantwell. Laura kept her seat by the window, while her husband still scowled gloomily from under his midnight brow.
