about ten o'clock
Ann Mary made up her mind that she would not undress herself , and that she would keep the lamp burning all night . She climbed into the big yellow-posted bedstead , and the cat cuddled up to her and purred . Ann Mary lay in bed and stared at the white satin scrolls on the wall-paper , and listened for noises . She heard a great many , but they were all mysterious and indefinable , till about ten o'clock . Then she sat straight up in bed and her heart beat fast . She certainly heard sleigh-bells ; the sound penetrated even to the dark bedroom . Then came a jarring pounding on the side door .
