She looked up and saw the level ray of moonlight overhead. Whoever climbed the stair must pass up into the light and be visible, but from where she stood she could only see the side of the stair like a black wall. But she must see—she must. If some one had come out of the darkness where there was no door she must know who it was. Her bare feet made no sound as she moved from the sheltering doorway. Step by step she kept pace with those slow mounting footsteps. She passed the steel gate, and, feeling her way along the wall, came to a standstill by the cold black hearth. Then, with her whole body tense, she turned and looked up. There was a darker shadow among the shadows, a shadow that moved upwards, towards the beam of moonlight. Jane watched, breathless, and from where The Portrait hung, the sombre eyes of Raymond Heritage seemed to watch too. Out of blackness into dusk a something emerged; one step more and the moonlight fell on a dark hood. Up into the light came a cloaked figure, draped from head to foot, shapeless. On the top step it turned. Jane caught her breath. It was Lady Heritage. She stood there for a long minute, her left hand just resting on the newel post with its twining tendrils and massive overhanging grapes. The light shone full upon her, and her face was sharpened, blanched, and sorrowful. Her eyes seemed to look into unfathomable depths of gloom. The amber, the rose, and the violet of the stained glass fell in a hazy iridescence upon the black of her cloak. In front the cloak fell away and showed the straight white linen of an overall, and cloak and overall were deeply stained with dull wet smears. A piece of the stuff hung jagged from a tear. Jane looked, and could not take her eyes away. “Oh, she’s so unhappy,” she said to herself. With a quick movement Raymond Heritage pushed the hood back from her hair. Then she turned, faced her own portrait for a moment, and passed slowly out of sight. Jane heard a door close very softly. She stood quite still and waited, gathering her courage. She would have to mount the stair and pass through that light before she could reach the safely shadowed corridor. Just for a moment it seemed as if she could not do it. Her feet seemed to cleave to the ground. Five minutes passed, and another five. Jane felt herself becoming rigid, and with a tremendous effort, she took one step forward, but only one, for as her foot touched a new cold patch of floor, some one moved overhead. For an instant a little pencil of electric light jabbed into the darkness and went out again. The next moment Mr. Ember stepped into the moonlight. He too wore a linen overall, and in his left hand he carried the mask-like head-dress which was in use in the laboratories. His right hand held a torch.
