“How did you discover I was in this room?” asked Mildred.

“Old Norris, whom I saw on my arrival, told me I should find you in the library, and I concluded you were alone; but I have found a friend as well. And now I can answer no more questions.”

“Ever mysterious and incomprehensible!” cried Mildred. “I do not like to part with you thus.”

“You must!” he rejoined. “It is necessary that I should be in London to-night.”

He then bade them both farewell, tenderly embracing his sister, and renewing his thanks to Sir Bridgnorth.

Just as he was about to depart, the door was opened by old Norris, who called out, “Mrs. Calverley is coming to the library!”

“I won't see her!” cried Chetwynd, fiercely.

But there was no retreat, and he was compelled to remain.

In another moment, Mrs. Calverley appeared. Her astonishment at beholding Chetwynd may be imagined; nor, though she strove to veil it, could she altogether conceal her annoyance.

“I did not expect to find you here, Chetwynd,” she said.
