"It is a strange time for Harry to go away," she said quietly, from the library window.

"He probably has a reason."

"Why don't you say it?" she said suddenly, turning on me. "I know what you think. You believe he only pretended he was robbed!"

"I should be sorry to think anything of the kind," I began. But she did not allow me to finish.

"I saw what you thought," she burst out bitterly. "The detective almost laughed in his face. Oh, you needn't think I don't know: I saw him last night, and the woman too. He brought her right to the gate. You treat me like a child, all of you!"

In sheer amazement I was silent. So a new character had been introduced into the play—a woman, too!
