By degrees, as her eyes grew accustomed to the gloom, Dorothy became aware that the river seemed to be alive with boats of all sorts and kinds. She had expected to find it deserted; she was surprised to find that it seemed to be more crowded even than it had been in the daytime. Remembering the servant's recommendation to stoop, so that her figure might not be too clearly visible against the skyline, she made the best of her way to the steps, up which Frances had hurried, out of the boat, when she first saw her on the lawn. For one to whom the place was not familiar, in that light they were not easy to find. She stumbled on them more by chance than anything else. She began, cautiously, to descend them. She could not make out how many there were; and had gone down six when, feeling for the seventh, she touched the surface of the water with the sole of her shoe. Starting back just in time to save herself from stepping into the stream, she sat down, unintentionally, and with more force than was quite pleasant, on one of the steps at her back. The unexpected nearness of the water startled her; she did not know what she had escaped. Had she completed that step she might have gone head foremost into the river. She tried to make out where the boat was of which the servant girl had spoken, and presently could see it dimly. It seemed to be a long way off, how was she to get at it? Wholly unacquainted with riverine methods it did not occur to her to look for the cord by which it was tied, and so draw it towards her. Which was perhaps well; for, though she had never been in a small boat in her life, how she was going to navigate one in the darkness, all alone, was a problem she did not stay to contemplate. As she still sat on the step of which she had so unwillingly made a seat, dubious, fearful, the whole dark world was lit up by a vivid flash of lightning; and in what seemed to her to be its sudden, unearthly glow she saw, right in front of her, the face of the man who had killed George Emmett; saw it for one astounding moment, with more than normal plainness. Then, as suddenly as it came, it went, blotted out by the returning darkness. Whether she had seen a vision, or been the victim of an optical delusion, she had not a notion. For a moment or two all was still. Then a voice came to her through the blackness. "Can you tell me whereabouts I shall find Mr Vernon's house?" It was the voice of the man. As she heard it every muscle in Dorothy's body seemed to be attacked by a sort of tetanus. Whatever doubt she might have had about the face, as to whether or not it was an optical delusion, she had none whatever about the voice. She had heard it too recently--under circumstances of too much import--not to be sure of its identity when she heard it again. In it was a tone which had not been in it when she heard it in that sitting-room in "The Bolton Arms"; none the less was she sure that it was the same voice.
