"I have never had any doubt about that. I expect to see him to-morrow, but I shall find it hard to utter my errand quick enough. There will be a minute when he may misunderstand me. I dread that minute."

"Perhaps, you can avoid it. Perhaps after you have positively identified him I can do the rest. We will arrange it so, if we can."

Her eyes flashed gratitude, then took on a new expression. She had chanced to glance again at Miss Weeks, and Miss Weeks was not looking quite natural. She was still crocheting, or trying to, but her attitude was constrained and her gaze fixed; and that gaze was not on her work, but directed towards a small object at her side, which Reuther recognised from its open lid to be the little lady's work-box.

"Something is the matter with Miss Weeks," she confided in a low whisper to Mr. Black. "Don't turn; she's going to speak."

But Miss Weeks did not speak. She just got up, and, with a careless motion, stood stretching herself for a moment, then sauntered up to the table and began showing her work to Reuther.

"I've made a mistake," she pettishly complained. "See if you can find out what's wrong." And, giving the work into Reuther's hand, she stood watching, but with a face so pale that Mr. Black was not astonished when she suddenly muttered in a very low tone:

"Don't move or show surprise. The shade of the window is up, and somebody is looking in from outside. I saw his face reflected in the mirror of my work-box. It isn't any one I know, but he was looking very fixedly this way and may be looking yet. Now I am going to snatch my work. I don't think you're helping me one bit."

She suited the action to the word; shook her head at Reuther and went back to her old position on the hearth.

"I was afraid of it," murmured Reuther. "If we take the ride to-morrow, it will not be alone. If, on the other hand, we delay our trip, we may be forestalled in the errand upon which so much depends. We are not the only ones who have heard of the strange young man at Tempest Lodge."

The answer came with quick decision. "There is but one thing for us to do. I will tell you what it is a little later. Go and sit on the hearth with Miss Weeks, and mind that you laugh and chat as if your minds were quite undisturbed. I am going to have a talk with our host."
