They bade good-by to Frona and St. Vincent and went off disputing under the stars in the direction of the Opera House.

Gregory St. Vincent heaved an audible sigh. "At last."

"At last what?" Frona asked, incuriously.

"At last the first opportunity for me to tell you how well you did. You carried off the final scene wonderfully; so well that it seemed you were really passing out of my life forever."

"What a misfortune!"

"It was terrible."

"No."

"But, yes. I took the whole condition upon myself. You were not Nora, you were Frona; nor I Torvald, but Gregory. When you made your exit, capped and jacketed and travelling-bag in hand, it seemed I could not possibly stay and finish my lines. And when the door slammed and you were gone, the only thing that saved me was the curtain. It brought me to myself, or else I would have rushed after you in the face of the audience."

"It is strange how a simulated part may react upon one," Frona speculated.

"Or rather?" St. Vincent suggested.
