"I should like your opinion on the subject," she said graciously, "and then I will see if the case can be gone on with."

Naball, who had been keeping his keen eyes on her face the whole time, bowed.

"Tell me all the details of the robbery," he observed cautiously.

"They are simple enough," replied Kitty, folding her hands. "I bring them home from the theatre every night, and usually put them in the safe, which is in my room. On Saturday night, however, I was tired, and, I must confess, rather careless, and as the case was on my dressing-table, I placed it in the drawer of my looking-glass, to save me the trouble of going to the safe. I gave a supper party on Sunday night, and when every one had gone away, I went upstairs to bed, and found the window open; recollecting where I had put the diamonds, I opened the drawer and found them gone. My servants examined the ground beneath the window, and found footmarks on the mould of the flower-bed, so I suppose the thief must have entered by the window, stolen the jewels, and made off with them."

When she had finished, Naball remained silent for a minute, but just as Fenton was about to speak, he interposed.

"I will ask you a few questions, madame," he said thoughtfully. "When did you see the diamonds last?"

"About six o'clock on Sunday night. I opened the drawer to get something, and saw the case."

"Not the diamonds?"

"They were in the case."

"Are you sure?"
