He raised it only a few inches, and then, taking up the lantern, peered into the interior of the coffin, at the same time waving his hand in dismissal to Ah Fu. For a while he stood there, peering into the interior, and then, lowering the lid again, he relocked this gruesome receptacle and, lantern in hand, began to mount the stair. Durham inhaled deeply. He realized that during the last few seconds he had been holding his breath. Now, as he began to creep back down the slope, he discovered that his hands were shaking. He dropped down into the court again, and for several minutes leaned against the wall, endeavouring to reason out an explanation of what he had seen, and in a measure to regain his composure. There was a horror underlying it all which he was half afraid to face. But the real clue to the mystery still eluded him. Whether what he had witnessed were some kind of obscene ceremony, or whether an explanation more vile must be sought, he remained undetermined. He must repeat his exploit, if possible, and once more gain access to the room which contained the lacquer coffin. But the adventure was very distasteful. He recollected the smell of the place, and the memory brought with it a sense of nausea. He thought of Lala Huang, and his ideas became grotesque and chaotic. Yet the solution of the mystery lay at last within his grasp, and to the zest of the investigator everything else became subjugated. He walked slowly away, silent in his rubber-soled shoes. IX THE PICTURE ON THE PAD Lala Huang lay listening to the vague sounds which disturbed the silence of the night. Presently her thoughts made her sigh wearily. During the lifetime of her mother, who had died while Lala was yet a little girl, life had been different and so much brighter. She imagined that in the mingled sounds of dock and river which came to her she could hear the roar of surf upon a golden beach. The stuffy air of Limehouse took on the hot fragrance of a tropic island, and she sighed again, but this time rapturously, for in spirit she was a child once more, lulled by the voice of the great Pacific. Young as she was, the death of her mother had been a blow from which it had taken her several years to recover. Then had commenced those long travels with her father, from port to port, from ocean to ocean, sometimes settling awhile, but ever moving onward, onward. He had had her educated after a fashion, and his love for her she did not doubt. But her mother's blood spoke more strongly than that part of her which was Chinese, and there was softness and a delicious languor in her nature which her father did not seem to understand, and of which he did not appear to approve. She knew that he was wealthy. She knew that his ways were not straight ways, although that part of his business to which he had admitted her as an assistant, and an able one, was legitimate enough, or so it seemed.
