“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. There were steps in the passage. Lucas quickly turned back the drugget, thrust the document into some hiding-place there, and covered it over.
