The Classic Mystery Collection - Arthur Conan Doyle [5411]
As the police beat left Limehouse Pier, a clammy south-easterly breeze blowing up-stream lifted the fog in clearly defined layers, an effect very singular to behold. At one moment a great arc-lamp burning above the Lavender Pond of the Surrey Commercial Dock shot out a yellowish light across the Thames. Then, as suddenly as it had come, the light vanished again as a stratum of mist floated before it.
The creaking of the oars sounded muffled and ghostly, and none of the men in the boat seemed to be inclined to converse. Heading across stream they made for the unseen promontory of the Isle of Dogs. Navigation was suspended, and they reached midstream without seeing a ship's light. Then came the damp wind again to lift the fog, and ahead of them they discerned one of the General Steam Navigation Company's boats awaiting an opportunity to make her dock at the head of Deptford Creek. The clamor of an ironworks on the Millwall shore burst loudly upon their ears, and away astern the lights of the Surrey Dock shone out once more. Hugging the bank they pursued a southerly course, and from Limehouse Reach crept down to Greenwich Reach.
Fog closed in upon them, a curtain obscuring both light and sound. When the breeze came again it had gathered force, and it drove the mist before it in wreathing banks, and brought to their ears a dull lowing and to their nostrils a farmyard odor from the cattle pens. Ghostly flames, leaping and falling, leaping and falling, showed where a gasworks lay on the Greenwich bank ahead.
Eastward swept the river now, and fresher blew the breeze. As they rounded the blunt point of the "Isle" the fog banks went swirling past them astern, and the lights on either shore showed clearly ahead. A ship's siren began to roar somewhere behind them. The steamer which they had passed was about to pursue her course.
Closer in-shore drew the boat, passing a series of wharves, and beyond these a tract of waste, desolate bank very gloomy in the half light and apparently boasting no habitation of man. The activities of the Greenwich bank seemed remote, and the desolation of the Isle of Dogs very near, touching them intimately with its peculiar gloom.
A light sprang into view some little distance inland, notable because it shone lonely in an expanse of utter blackness. Kerry broke the long silence.
"Dougal's," he said. "Put us ashore here."
The police boat was pulled in under a rickety wooden structure, beneath which the Thames water whispered eerily; and Kerry and Seton disembarked, mounting a short flight of slimy wooden steps and crossing a roughly planked place on to a shingly slope. Climbing this, they were on damp waste ground, pathless and uninviting.
"Dougal's is being watched," said Kerry. "I think I told you?"
"Yes," replied Seton. "But I have formed the opinion that the dope gang is too clever for the ordinary type of man. Sin Sin Wa is an instance of what I mean. Neither you nor I doubt that he is a receiver of drugs--perhaps the receiver; but where is our case? The only real link connecting him with the West-End habitue is his wife. And she has conveniently deserted him! We cannot possibly prove that she hasn't while he chooses to maintain that she has."
"H'm," grunted Kerry, abruptly changing the subject. "I hope I'm not recognized here."
"Have you visited the place before?"
"Some years ago. Unless there are any old hands on view tonight, I don't think I shall be spotted."
He wore a heavy and threadbare overcoat, which was several sizes too large for him, a muffler, and a weed cap--the outfit supplied by Seton Pasha; and he had a very vivid and unpleasant recollection of his appearance as viewed in his little pocket-mirror before leaving Seton's room. As they proceeded across the muddy wilderness towards the light which marked the site of Dougal's, they presented a picture of a sufficiently villainous pair.
The ground was irregular, and the path wound sinuously about mounds of rubbish; so that often the guiding light was lost, and they stumbled blindly among nondescript litter, which apparently
