knew what he was talking about, and always salted what he knew with happy flashes of wit and humour.Oliver accompanied the two ladies back into the drawing-room, and his mother did not know whether to be glad or sorry that she had not had a few minutes alone with the younger woman. Sometimes it seemed as if she and Laura never were alone together now. Was it possible that of late Laura was deliberately avoiding her? As this half suspicion came into Mrs. Tropenell's mind she looked up and saw her son's eyes fixed on her face. There was something imperious, imploring, commanding, in the look he bent on her. She saw that he was willing her to go away--to leave him, alone, with Laura....Under the spell of that look she got up. "I must go upstairs for my work," she said quietly.

After he had shut the door on his mother, Oliver Tropenell walked back to the place where he had stood a moment ago. But he did not come any nearer than he had been before to his guest, and his manner remained exactly what it had been when they had been three, instead of being, as they were now, two, in that dimly lighted room. Still, both he and Laura, in their secret, hidden selves, were profoundly conscious that
