"I've only done my best," he responded, modestly.

Isabel could say nothing for some little time. She was furiously angry with Aunt Francesca because she had not told her. The day that Rose went away, everyone in the house had been very glad about something, even to the servants, but she had asked no questions and received no information, except that Rose had been obliged to go away very suddenly upon business of immediate importance.

"You must be awful glad," said Juliet, to Isabel.

"Of course," answered Isabel, coldly, clearing her throat.

"He must feel pretty good," Romeo observed.

"Yes," returned Doctor Jack, "except that he's lost his girl."

Isabel flushed and nervously turned on her finger the diamond ring that she still wore.

"He's had fierce luck with girls," resumed the Doctor, unthinkingly. "One passed him up because he was hurt, and the other because he was going to get well."

The tense silence that ensued indicated that he had made a mistake of some sort. It had not occurred to him that the twins did not know of Allison's engagement to Rose, nor did he suspect Isabel's identity.

Juliet was staring at Isabel in pained surprise. "Did you?" she asked, slowly, "throw him over because he got hurt?"
