"Yes, that is what they are about. It is her doing, but it is my fault."
"Your fault!" exclaimed Laura. "But surely there never even was such a letter as she refers to. Do you understand at all?"
"Yes, I understand much too well. She has done this for a distinct purpose. Tell me in the first place one thing. Do you still trust me in the face of such evidence as this?"
"I trust you as much as ever," answered Laura.
"Thank you," he said simply, and he looked into her deep eyes a moment before he continued. "There are two stories to tell, yours and mine. Tell yours first. Tell me how you came by the copy you speak of. Who sent it to you, and when?"
As briefly as she could, Laura gave him all the details she could remember from the day she had received the first request for help from Maria B. It was painful to her to repeat what she could of the substance of the copy sent her, but she went through with it to the end.
"That letter is not among these," said Ghisleri, thoughtfully. "It is one of the two which have been kept back for future use. Now let me tell you what I can remember. Do not be surprised that I should never have told you the story before. Since you can trust me in such a matter as this, you will believe me when I say that there was a good reason for not telling you."
He gave a concise account of the conversation which had taken place between himself and Adele at the Montevarchi's party, omitting only what referred to his own suspicions concerning the manner of Arden's death. If possible, he meant always to conceal that side of the question from Laura. But it was necessary to tell her something about the document constantly mentioned in the letters.
"There is a story in circulation," he said, "to the effect that when Donna Adele was ill at Gerano nearly two years ago, she was unwilling to confess to the parish priest, and wrote a confession to be sent to her confessor in Rome. A servant stole it, says the story, and it is supposed to be in existence, passing from hand to hand in society. It is quite possible that she believes that I bought it of the thief. But I doubt even that. She has most probably regained possession of it before attempting this stroke. And this is almost what I suggested to her in a general way, and laughing, as one way of ruining a man. I remember my own words—an injury that would make a woman who loves a man turn upon him. Substitute friendship for love, and the case is almost identical."
"Yes," Laura answered thoughtfully. "Substitute friendship for love." She hardly knew why she repeated the words, and a moment later a faint colour rose in her cheeks.
