It was after five o’clock when Sherlock Holmes left me, but I had no time to be lonely, for within an hour there arrived a confectioner’s man with a very large flat box. This he unpacked with the help of a youth whom he had brought with him, and presently, to my very great astonishment, a quite epicurean little cold supper began to be laid out upon our humble lodging-house mahogany. There were a couple of brace of cold woodcock, a pheasant, a pâté de foie gras pie with a group of ancient and cobwebby bottles. Having laid out all these luxuries, my two visitors vanished away, like the genii of the Arabian Nights, with no explanation save that the things had been paid for and were ordered to this address.

Just before nine o’clock Sherlock Holmes stepped briskly into the room. His features were gravely set, but there was a light in his eye which made me think that he had not been disappointed in his conclusions.

“They have laid the supper, then,” he said, rubbing his hands.
