"No; and in the excitement I was not presented to Lady Leconbridge," Hartmann answered.

"Was she very much agitated?" I asked.

"She was curiously calm."

"I believe you know something about precious stones, Mr. Hartmann?"

"Gems are a hobby of mine," he said with a smile.

"I want your opinion. Do you think paste might deceive an expert?"

"At a casual glance—yes, if it were good paste."

"For instance," I said, "if Lady Leconbridge had been wearing the necklace when you approached her would you have known had it been paste?"

"I should," he answered, with a satisfied smile.

"But yours would have been only a casual glance. A man is more likely to be interested in a woman's beauty than in the jewels she is wearing. Besides, you would not expect Lady Leconbridge to be wearing paste."
