“And for—well, for others?”

“If you mean Kilgariff, yes. If you mean the conventional people, no. So you had better never say anything about it to them.”

At Dorothy’s mention of Kilgariff’s name, Evelyn started as if shocked. But quickly recovering herself, she said with passion in her tones:—

“You are the very best woman in the world, Dorothy. I shall not long have any secrets from you.”

The girl’s agitation was ungovernable. Emotionally she had passed through a greater crisis than she had ever known before, and her nerves were badly shaken. Without trying to utter the words that would not rise to her quivering lips, she took refuge in the laboratory, where she set to work with the impatience of one who must open a safety valve of some kind, or suffer collapse. Most women of her age, similarly agitated, would have gone to their chambers instead, and vented their feelings in paroxysms of weeping. Evelyn Byrd was not given to tears. Perhaps bitter experience had conquered that feminine tendency in her, though very certainly it had not robbed her of her intense femininity in any other way.

When Dorothy joined her in the laboratory an hour later, the girl was engaged in an operation so delicate that the tremor of a finger, the jarring of a sharply closed door, or even a sudden breath of air would have ruined the work.

“Step lightly, please,” was all that she said. Dorothy saw that the girl had completely mastered herself.

And Dorothy admired and rejoiced.
