The man at the other end clipped out a “Very well, madam,” and hung up.

Betty was puzzled. Why had Prosper sent her this message, made this appointment by his servant? Perhaps because he was afraid that, in her exaggerated caution, she might refuse to meet him if she could explain to him the reason for her refusal, or gauge the importance of his request. With a servant she could do neither, and the very uncertainty would force her to accept. It was a dreadful day. Nobody would be out, certainly not at the tea-hour, to look at Foster’s pictures—an insignificant exhibition. Betty felt triumphant. At last, this far too acquiescent lover had rebelled against her decree of silence and separation.

At five o’clock she stepped out of her taxicab, made a run for shelter, and found herself in the empty exhibition rooms. She checked her wrap and her umbrella, took a catalogue from the little table, chatted for a moment with the man in charge, then moved about, looking carelessly at the pictures. No. 88 in the inner room! Her heart was beating violently, the hand in her muff was cold. She went slowly toward the inner room and saw at once that, under a small canvas at its far end, Prosper stood waiting for her.

He waited even after he had seen her smile and quickening step, and when he did come forward, it was with obvious reluctance. Betty’s smile faded. His face was haggard and grim, unlike itself; his eyes lack-luster as she had never seen them. This was not the face of an impatient lover. It was—she would not name it, but she was conscious of a feeling of angry sickness.

He took her hand and forced a smile.

“Betty, I thought you disapproved of this kind of thing. I think, myself, it’s rather imprudent to arrange a meeting through your maid.”

Betty jerked away her hand, drew a sharp breath. “What do you mean? I didn’t arrange this meeting. It was you—your man.”

They became simultaneously aware of a trap. It had sprung upon them. With the look of trapped things, they stared at each other, and Betty instinctively looked back over her shoulder. There stood Jasper in the doorway of the room. He looked like the most casual of visitors to an art-gallery, he carried a catalogue in his hand. When he saw that he was seen he smiled easily and came over to them.

“You will have to forgive me,” he murmured pleasantly; “you see, it was necessary to see you both together and Betty is not willing to allow me an interview. I am sorry to have chosen a public place and to have used a trick to get you here, but I could not think of any other plan. This is really private enough. I have arranged this exhibition for Foster and it is closed to the public to-day. We got in by special permit—a fact you probably missed. And, after all, civilized people ought to be able to talk about anything without excitement.”

Betty’s eyes glared at him. “I will not stay! This is insufferable!”
