She understood now why she had found so much that was white in him, but so much that was false. His presence seemed to be very near her. Something caressing in his voice echoed in her mind. She found herself to be listening to the muted sounds of Limehouse and of the waterway which flowed so close beside her.

That old longing for the home of her childhood returned tenfold, and tears began to trickle down her cheeks. She was falling in love with this man whose object was her father's ruin. A cold terror clutched at her heart. Even now, while their friendship was so new, so strange, there was a query, a stark, terrifying query, to stand up before her.

If put to the test, which would she choose?

She was unable to face that issue, and dropped back upon her pillow, stifling a sob.

Yes, he was a detective. In some way her father had at last attracted the serious attention of the law. Rumours of this were flying round Chinatown, to which she had not been entirely deaf. She thought of a hundred questions, a hundred silences, and grew more and more convinced of the truth.

What did he mean to do? Before her a ghostly company uprose—the shadows of some she had known with designs upon her father. John Hampden's design was different. But might he not join that mysterious company?

Now again she suddenly sprang upright, this time because of a definite sound which had reached her ears from within the house: a very faint, bell-like tinkling which ceased almost immediately. She had heard it one night before, and quite recently; indeed, on the night before she had met John Hampden. Cohen—Cohen, the Jew, had died that night!

She sprang lightly on to the floor, found her slippers, and threw a silk kimono over her nightrobe. She tiptoed cautiously to the door and opened it.

It was at this very moment that old Huang Chow, asleep in his cell-like apartment, was aroused by the tinkling of a bell set immediately above his head. He awoke instantly, raised his hand and stopped the bell. His expression, could anyone have been present to see it, was a thing unpleasant to behold. Triumph was in it, and cunning cruelty.

His long yellow fingers reached out for his hornrimmed spectacles which lay upon a little table beside him. Adjusting them, he pulled the curtains aside and shuffled silently across the large room.
