She further remembered how he had put the bag down on the floor of the top front room, and then, forgetting what he had done, how he had asked her eagerly, in a tone of angry fear, where the bag was—only to find it safely lodged at his feet! As time went on Mrs. Bunting thought a great deal about that bag, for, strange and amazing fact, she never saw Mr. Sleuth’s bag again. But, of course, she soon formed a theory as to its whereabouts. The brown leather bag which had formed Mr. Sleuth’s only luggage the afternoon of his arrival was almost certainly locked up in the lower part of the drawing-room chiffonnier. Mr. Sleuth evidently always carried the key of the little corner cupboard about his person; Mrs. Bunting had also had a good hunt for that key, but, as was the case with the bag, the key disappeared, and she never saw either the one or the other again. CHAPTER V. How quietly, how uneventfully, how pleasantly, sped the next few days. Already life was settling down into a groove. Waiting on Mr. Sleuth was just what Mrs. Bunting could manage to do easily, and without tiring herself. It had at once become clear that the lodger preferred to be waited on only by one person, and that person his landlady. He gave her very little trouble. Indeed, it did her good having to wait on the lodger; it even did her good that he was not like other gentlemen; for the fact occupied her mind, and in a way it amused her. The more so that whatever his oddities Mr. Sleuth had none of those tiresome, disagreeable ways with which landladies are only too familiar, and which seem peculiar only to those human beings who also happen to be lodgers. To take but one point: Mr. Sleuth did not ask to be called unduly early. Bunting and his Ellen had fallen into the way of lying rather late in the morning, and it was a great comfort not to have to turn out to make the lodger a cup of tea at seven, or even half-past seven. Mr. Sleuth seldom required anything before eleven. But odd he certainly was. The second evening he had been with them Mr. Sleuth had brought in a book of which the queer name was Cruden’s Concordance. That and the Bible—Mrs. Bunting had soon discovered that there was a relation between the two books—seemed to be the lodger’s only reading. He spent hours each day, generally after he had eaten the breakfast which also served for luncheon, poring over the Old Testament and over that strange kind of index to the Book.
