"'Mrs. Markham,' she says, 'wanted that I should tell you she has sitters unexpected. There's some of her devil doin's going on downstairs to-night. She wanted me to catch you when you came in and ask you to go very quiet to your room.' "While I went upstairs, I listened hard. Just before I came out on the landing of the servants' hall, I heard a bell ring, away down below. Just a little ring--b-r-r. Now, you know if there's one thing more 'n another that I've got, it's ears--and ears that remember, too. I hadn't been a day in that house when I knew every bell in it and who was ringin' besides. This wasn't any of 'em. But that wasn't the funny thing. _It lasted just about as long as my foot rested on a step of the stairs_. I didn't make the break of going back and ringin' again; but I remembered that step--third from the top. "'T ain't easy to admit you've been fooled, and 't ain't easy to give up somebody you've believed in. I couldn't have slept that night even if I'd wanted. I opened the registers in my room, because open registers help you to hear things, and sat in the darkness. I could catch that the sitting was over, because the front door slammed. Then Ellen came upstairs, and the bell rang b-r-r again. I could hear someone come upstairs to the second floor, where Mrs. Markham and the girl have their rooms. I listened for that bell when she struck the stairs. I couldn't hear nothing. The current has been switched off, thinks I. Maybe it was ten minutes later when I got a faint kind of thud, like somebody had let down a folding bed, though there ain't a one of those man-killers in our house. Sort of stirred up a recollection, that sound. I lay puzzling, and the answer came like a flash. Worst fake outfit I ever had anything to do with was Vango's Spirit Thought Institute in St. Paul. I've told you before how ashamed I am of that. I left because there's some kinds of work I won't stand for. Well, he used a ceiling trap for his materializin'; though the wainscot is a sight better and more up-to-date in my experience. When he let it drop careless, in practicing before the seance, it used to make a noise like that. I fell asleep by-and-bye; and out of my dreams, which was troubled and didn't bring nothing definite, I got the general impression that Mrs. Markham wasn't all right and that I'd been fooled.
