"Are you going back to Bourne End or to Hampstead?" Arnold asked.

She hesitated.

"Really, I am not quite sure," she replied, meeting his gaze without flinching. "I am beginning to find the heat in town insufferable. I think, perhaps, that I shall go to Bourne End."

"In that case," Arnold said, "will you allow me to see you there to-night?"

"To-night?" she repeated, as though in surprise.

"Without a doubt."

She did not answer him for a moment. Meanwhile, the telephone rang, and Mr. Jarvis was presently engrossed in a business conversation with a customer. Arnold lowered his voice a little.

"Our discussion at luncheon was only postponed," he reminded her. "We have seen these documents. We know now that Mr. Weatherley had some reason to fear an interruption to his everyday life. Directly or indirectly, that interruption is connected with certain things of which you and I have spoken together. I am going to ask you, therefore, to keep your promise. I am going to ask you to tell me everything that you know."

"Are you not afraid," she asked, "that I shall consider you a very inquisitive young man?"

"I am afraid of nothing of the sort," Arnold replied. "Mr. Weatherley's disappearance is too serious a matter for me to take such trifles into account."
