"Mrs. Chepstow!"

At the sound of Nigel Armine's voice Mrs. Chepstow started slightly, like a person recalled abruptly from a reverie, looked up, and smiled.

"You are here! I'm all alone. But I was hungry, so I had to brave the rabble."

"I want to introduce a friend to you. May I?"

"Of course."

Armine moved, and Doctor Isaacson stood by Mrs. Chepstow.

"Doctor Meyer Isaacson, Mrs. Chepstow."

The Doctor scarcely knew whether he had expected Mrs. Chepstow to recognize him, or whether he had anticipated what actually happened--her slight bow and murmured "I'm delighted to meet you." But he did know that he was not really surprised at her treatment of him as an entire stranger. And he was glad that he had said nothing to Armine of her visit to Cleveland Square.

"Aren't you going to sit down and talk to me for a little?" Mrs. Chepstow said. "I'm all alone and horribly dull."

"May we?"

Armine drew up a chair.

"Sit on my other side, Doctor Isaacson. I've heard a great deal about you. You've made perfect cures of most of my enemies."

There was not the least trace of consciousness in her manner, not the faintest suspicion of embarrassment in her look, and, as he sat down, the Doctor found himself admiring the delicate perfection of her deceit, as he had sometimes admired a subtle nuance in the performance of some great French actress.
