Dusk at last, and the noises in the streets growing fainter. They had agreed upon their plan of action, and had decided to take a four-wheeled cab to Woolwich—choosing that conveyance, as being likely to attract less attention than a hansom—and then to walk to The Three Watermen. They slipped down the side of the hay wagon, and crept out of the stable-yard into the streets. Philip dived into the first crawling “growler” he saw, leaving Cripps to give the necessary directions. Philip leaned back in the cab, as much out of sight as possible, and began to wonder, with fiery impatience, whether they would be too late—or whether they would miss those of whom they were in pursuit—or whether Madge had really come to London, and, if so, where she was at that time. After a long journey through endless streets, Cripps stopped the vehicle, and they alighted. Philip found himself at the corner of a narrow and very dirty street, in a neighbourhood evidently of the poorest class—and yet a neighbourhood which seemed familiar. “Now, Mr. Chater,” said the little man, who was evidently growing more nervous at every step they took—“Now comes the necessity for greater caution than ever. We—we may absolutely ruin everything, if we are too precipitate. We must find out first where Ogledon is, and whether or not he has gone to the hut spoken of by the Shady ’un. Ah—you don’t know what Ogledon is—or what he is capable of.” “I can guess,” said Philip, quietly—“and that makes me the more anxious to get on without delay. How far are we from the place?” “A hundred yards or so,” replied Cripps, who was beginning to tremble like a leaf. “You don’t—don’t feel that you would like—like to turn back, I suppose?” “Turn back!” cried Philip with a grim laugh. “Turn back now—when I am within touch of this man! No—not if greater dangers than any I have met yet fronted me. Show me the way, wherever it may be!” The Doctor led the way down a side street, which brought them, with another sharp turn to the left to The Three Watermen; Philip knew it in a moment. “I know the way now,” he said—“I have been to the spot before. Come on—let us waste no further time.” In his eagerness, he dived himself into that small alley-way, into which he had gone on that first night of his coming to the place. Only when he reached the end of it, did he look round for his companion; but Cripps was gone. His fears had been too much for him, and, watching his opportunity, he had fled. There was no time to wait for him, or to look for him; Philip made his way rapidly in the direction of those tumble-down out-houses he had noticed on the night he found his brother’s body. Coming within sight of these, he suddenly stopped, and dropped down behind the shelter of a ruined boat, which lay half buried in the mud. For, at the door of one of those dilapidated buildings, stood the Shady ’un, as if on guard.
