“It was a letter of mine, Mr. Holmes, an indiscreet letter written before my marriage—a foolish letter, a letter of an impulsive, loving girl. I meant no harm, and yet he would have thought it criminal. Had he read that letter his confidence would have been for ever destroyed. It is years since I wrote it. I had thought that the whole matter was forgotten. Then at last I heard from this man, Lucas, that it had passed into his hands, and that he would lay it before my husband. I implored his mercy. He said that he would return my letter if I would bring him a certain document which he described in my husband's despatch-box. He had some spy in the office who had told him of its existence. He assured me that no harm could come to my husband. Put yourself in my position, Mr. Holmes! What was I to do?”

“Take your husband into your confidence.”

“I could not, Mr. Holmes, I could not! On the one side seemed certain ruin; on the other, terrible as it seemed to take my husband's paper, still in a matter of politics I could not understand the consequences, while in a matter of love and trust they were only too clear to me. I did it, Mr. Holmes! I took an impression of his key; this man Lucas furnished a duplicate. I opened his despatch-box, took the paper, and conveyed it to Godolphin Street.”

“What happened there, madam?”

“I tapped at the door as agreed. Lucas opened it. I followed him into his room, leaving the hall door ajar behind me, for I feared to be alone with the man. I remember that there was a woman outside as I entered. Our business was soon done. He had my letter on his desk; I handed him the document. He gave me the letter. At this instant there was a sound at the door.
