"How very kind," sneered Cervera, with a bitter flash of her black eyes. "You shall yet suffer for this affront, Detective Carter."

"All right," said Nick. "But I have no time to speculate upon it now, so get yourself ready. Wait a bit, my lady! I'll go along with you!"

"With me? You insult me!"

"Oh, no, I don't. I want a look at your chamber before letting you out of my sight. I've seen rooms with more than one way out, and I don't intend that you shall elude me."

"You're a suspicious coward, sir!"

"Stow all that, señora, and lead the way," commanded Nick, bluntly.

Pale and resentful, with a sneer on her lips, Cervera led the way through, the hall, playing her part so artfully that Nick, ignorant of her late interview with Rufus Venner, was not much inclined to suspect her of duplicity just then.

Upon reaching the top of the hall stairs, Cervera switched on another light, and then that which illumined her chamber, into which she haughtily led the detective.

"A fine affront to suffer," she bitterly exclaimed, throwing herself into a chair. "Your conduct is despicable! You are no gentleman!"

"I am a detective," retorted Nick, "and I come pretty near knowing my business."
