And then he saw the snake, and his face wrinkled. He looked from Mirabelle to the girl on the bed, went over and examined her, but did not attempt to release the strap. It was Mirabelle who did that; Mirabelle who sponged the bruised face and loosened the dress. So doing, she felt a hand on her shoulder. “Come,” said Oberzohn. “I’m staying here with Joan, until——” “You come at once, or I will give you to my pretty little friends.” He pointed to the two snakes on the floor who still moved spasmodically. She had to step past Gurther, but that seemed easier than passing those wriggling, shining black ropes; and, her hand in his, she stumbled up the dark steps and eventually into the clean, sweet air of the night. He was dressed for a journey; she had noticed that when he appeared. A heavy cloth cap was on his curious-shaped head, and he looked less repulsive with so much of his forehead hidden. Though the night was warm, he wore an overcoat. They were passing between the wall and the factory when he stopped and put his hand before her mouth. He had heard voices, low voices on the other side of the wall, and presently the scrape of something. Without removing his hand from her face, he half dragged, half pushed her until they were clear of the factory. She thought they were going back to the house, which was in darkness, but instead, he led her straight along the wall, and presently she saw the bulk of the barge. “Stay, and do not speak,” he said, and began to turn a rusty wheel. With a squeak and a groan the water-gates opened inwards. What did he intend doing? There was no sign of a boat, only this old dilapidated barge. She was presently to know. “Come,” he said again. She was on the deck of the barge, moving forward to its bow, which pointed towards the open gate and the canal beyond. She heard him puff and groan as he strained at a rope he had found, and then, looking down, she saw the front of the barge open, like the two water-gates of a lock. Displaying remarkable agility, he lowered himself over the edge; he seemed to be standing on something solid, for again he ordered her to join him. “I will not go,” she said breathlessly, and turning, would have fled, but his hand caught her dress and dragged at her. “I will drown you here, woman,” he said, and she knew that the threat would have a sequel. Tremblingly she lowered herself over the edge until her foot touched something hard and yet yielding. He was pushing at the barge with all his might, and the platform beneath her grew in space. First the sharp nose and then the covered half-deck of the fastest motor-boat that Mr. Oberzohn’s money could buy, or the ingenuity of builders could devise. The old barge was a boat-house, and this means of escape had always been to his hand. It was for this reason that he lived in a seemingly inaccessible spot.
