"Surprised? Well, rather!" she exclaimed, in animated tones. "I was expecting our mutual friend, dear Mr. Venner, and supposed it was he who rang. But I'm just as pleased to see you."

"Yes?"

"Surely! Come in, Detective Carter. You are very, very welcome. I shall be so glad to renew our brief acquaintance. In fact, Detective Carter, I am quite charmed to see you."

"You'll not feel so chipper and charmed when you learn my business," said Nick to himself, as he entered and followed her to the library.

"Take a chair, Detective Carter, and try to feel perfectly at home," laughed Cervera, with bantering vivacity. "You have been here before, you know."

"Yes, indeed, I know," said Nick, dryly. "The night I had a taste of a choke pear, at the hands of your faithful guardians."

"Ah! but you shall be better treated this time," smiled Cervera, dropping into a chair opposite the detective, and fixing her sensuous, dark eyes on Nick's calm, unreadable face.

"I hope so, señora," he replied. "By the way, what has become of those two stalwart guardians of your treasures? Do you still retain them in your employ?"

It was second nature to Nick to feel his way in this crafty fashion, yet he did not really expect any resistance in arresting Cervera, who now laughed and shook her head, replying:

"No, I have let them go."
