I may have been seated there about an hour -- it was almost eight o'clock -- when I heard a knock at the door . `` Come in , '' I said , swinging round in the American chair , to find myself face to face with Sheriff Johnson . `` Why , Sheriff , come in ! '' I exclaimed cheerfully , for I was relieved at seeing him , and so realized more clearly than ever that the unpleasantness of the previous evening had left in me a certain uneasiness .
