"And now as a result of what we have done this evening with your help, the soul of Mrs. Carr is once more in the body of Mrs. Carr, and the soul of Tansy Saylor is in the body of Tansy Saylor. That is all. And now, good night."

The six-paneled door closed behind them. The pebbly path crunched under their feet.

"How did you know?" was Tansy's first question, "When I stood there in the doorway, blinking through those awful spectacles, gasping after the way I'd hurried with only the blind thought of finding you—how did you know?"

"Partly," he said reflectively, "because she gave herself away toward the end. She began to emphasize words in that exaggerated way of hers. But that wouldn't have been enough in itself. She was too good an actress. She must have been studying your mannerisms for years. And after seeing how well you played her part tonight, with hardly any preparation, I wonder that I ever did see through her."

"Then how did you?"

"It was partly the way you hurried up the walk—it didn't sound like Mrs. Carr. And partly something about the way you held yourself. But mainly it was that headshake you gave—that quick triple headshake, I couldn't fail to recognize it. And after that, I realized all the other things."

"Do you think," said Tansy softly, "that after this you'll never begin to wonder if I am really I?"

"I suppose I will," he said seriously. "But I believe I'll always be able to conquer my doubts."

And Tansy laughed.

But he was not yet over being serious. "I think that tonight we were a lot closer to a much bigger danger than even we ever guessed," he said. He had not yet surrendered to the reaction that gripped Tansy. "There's more behind this matter of the Balance than we may realize. There's a lot we'll do with this, but we'll want to go slowly and test every step of the way."
