A. Undoubtedly. He was poor, and wanted money, proved by his calling on Caprice and asking for some. He said he would be revenged because she did not give him more than a sovereign, and there would be no sweeter revenge than to steal her diamonds, as it would punish her, and benefit himself.

Q. Did he know the room where the diamonds were kept?

A. Yes. Caprice said her bedroom, and as Villiers had been several times to the house before, he knew where it was.

Q. Did Caprice know Villiers had stolen her jewels?

A. Extremely probably, hence her refusal to prosecute, as he was the husband of Madame Midas, whom she had treated so basely. The refusal to prosecute Villiers might be, in Caprice's opinion, an act of expiation.

When he had got thus far, Naball paused. After all, this was pure theory. He had not a single well authenticated fact to go on, but all the circumstances of the case seemed to point to Villiers, so he determined to go on the trail of Villiers, and find out what he was doing.

Mr. Villiers had of late been under the espionage of the police, owing to some shady transactions with which he was connected, so Naball knew exactly where to find him, and, putting on an overcoat, he sallied forth in the direction of the slums in Little Bourke Street, with the intention of calling on a Chinaman named Ah Goon, who kept an opium den in that unsavoury locality.

To his drinking habits Villiers now added that of being a confirmed opium smoker, and was on terms of intimacy with Ah Goon, in whose den he was accustomed to pass his evenings. Naball therefore intended to watch for Villiers, and find out, if possible, when, owing to drink and opium combined, he was not master of himself, what he had done on the night of the robbery after leaving Caprice.

He soon entered Little Bourke Street, and plunged into the labyrinth of slums, which he knew thoroughly. It was a clear, starry night, but the cool, fresh air was tainted in this locality by the foul miasma which pervaded the neighbourhood, and even the detective, accustomed as he was to the place, felt disgusted with the sickly odours that permeated the atmosphere.

Ah Goon's house was in a narrow right-of-way off one of the larger alleys, and there was a faint candle burning in the window to attract customers. Pausing at the door a moment, Naball listened to hear if there was any European within. The monotonous chant of a Chinese beggar could be heard coming down the alley, and every now and then the screams of two women fighting, while occasionally a number of noisy larrikins would come tramping heavily along, forming a strong contrast to the silent, soft-footed Orientals.
