“Yes,” she said wearily, “I thought over all that until my head ached. And I thought somebody else might have done it, and that he was somehow screening the guilty person. But that seemed wild. I could see no light in the mystery, and after a while I simply let it alone. All I was clear about was that Mr. Marlowe was not a murderer, and that if I told what you had found out, the judge and jury would probably think he was. I promised myself that I would speak to you about it if we should meet again; and now I’ve kept my promise.”

Trent, his chin resting on his hand, was staring at the carpet. The excitement of the hunt for the truth was steadily rising in him. He had not in his own mind accepted Mrs. Manderson’s account of Marlowe’s character as unquestionable. But she had spoken forcibly; he could by no means set it aside, and his theory was much shaken.

“There is only one thing for it,” he said, looking up. “I must see Marlowe. It worries me too much to have the thing left like this. I will get at the truth. Can you tell me,” he broke off, “how he behaved after the day I left White Gables?”

“I never saw him after that,” said Mrs. Manderson simply. “For some days after you went away I was ill, and didn’t go out of my room. When I got down he had left and was in London, settling things with the lawyers. He did not come down to the funeral. Immediately after that I went abroad. After some weeks a letter from him reached me, saying he had concluded his business and given the solicitors all the assistance in his power. He thanked me very nicely for what he called all my kindness, and said goodbye. There was nothing in it about his plans for the future, and I thought it particularly strange that he said not a word about my husband’s death. I didn’t answer. Knowing what I knew, I couldn’t. In those days I shuddered whenever I thought of that masquerade in the night. I never wanted to see or hear of him again.”

“Then you don’t know what has become of him?”

“No, but I dare say Uncle Burton—Mr. Cupples, you know—could tell you. Some time ago he told me that he had met Mr. Marlowe in London, and had some talk with him. I changed the conversation.” She paused and smiled with a trace of mischief. “I rather wonder what you supposed had happened to Mr. Marlowe after you withdrew from the scene of the drama that you had put together so much to your satisfaction.”

Trent flushed. “Do you really want to know?” he said.

“I ask you,” she retorted quietly.

“You ask me to humiliate myself again, Mrs. Manderson. Very well. I will tell you what I thought I should most likely find when I returned to London after my travels: that you had married Marlowe to live abroad.”

She heard him with unmoved composure. “We certainly couldn’t have lived very comfortably in England on his money and mine,” she observed thoughtfully. “He had practically nothing then.”
