She tried the door several times , but she could not get in . She said nothing to me ; and as I expected no assistance from her , I said nothing . Presently I heard her step on the stairs , hardly less heavy than that of her husband . I concluded that it must be five o'clock by this time ; and looking at my watch , I found it was half an hour later . I wanted to get out before dark ; and so far , I had not matured any plan to accomplish this purpose . I went to the window , and examined the boards which had been screwed up before it . I had a large jack-knife in my pocket , which I had carried for several years .
