"He has more courage than I," Gerard gravely acknowledged. "I could not have done it. A superb folly, unjust to himself and us. He might safely have confided in his father or me and have trusted Isabel to our care."

"Allan, she had his promise to tell no one and she held him to it. She was ill and hysterical with terrified shame; Isabel never could endure to be found at fault even in little things. She was not bad or wicked, but just a coward."

"She found strength enough to watch Corrie under torture week after week," he retorted, his golden-brown eyes hardening to agate. "If I had been killed under my car, Flavia, do you realize that Rupert would have brought your brother face to face with the electric chair? And Corrie would have shut his lips and endured it all. Don't ask me to pity Isabel Rose—I've lived this year with her victim."

Trembling under the control forced on herself, Flavia slipped her hand into his.

"I know, Allan, I know. Yet she did suffer to see his suffering. In her letter, she says that Corrie came to her at dawn, the last morning we were all at home, and called her out into the empty hall to beseech her for permission to tell you. He had not been to bed that night, at all. She never afterward forgot his desperate, worn face and that memory finally drove her to confession. But she refused him. He did break down then, and flashed out at her that he must and would tell you the truth, when he left her. Of course he did not do so. Allan, she declares that he then told you, that she knows it because you wrote to her that evening about your accident and said you would take care of Corrie whatever happened."

"I!"

"Your letter to me. She had been insane with dread all day, believing Corrie would fulfil his threat to tell you his innocence, and when Rupert came she saw only that idea confirmed. She knew of no relations between you and me. She thought only of herself."

Gerard looked at her, having no words; presently he sat down on the edge of the car at her feet, and they continued silent, hand in hand. Mr. Rose had found a camp-chair in the shadow of a wall, and sat watching the race in grim quiescence.
