The Case-Book of Sherlock Holmes

I fear that Mr. Sherlock Holmes may become like one of those popular tenors who, having outlived their time, are still tempted to make repeated farewell bows to their indulgent audiences. This must cease and he must go the way of all flesh, material or imaginary. One likes to think that there is some fantastic limbo for the children of imagination, some strange, impossible place where the beaux of Fielding may still make love to the belles of Richardson, where Scott's heroes still may strut, Dickens's delightful Cockneys still raise a laugh, and Thackeray's worldlings continue to carry on their reprehensible careers. Perhaps in some humble corner of such a Valhalla, Sherlock and his Watson may for a time find a place, while some more astute sleuth with some even less astute comrade may fill the stage which they have vacated.

His career has been a long one—though it is possible to exaggerate it; decrepit gentlemen who approach me and declare that his adventures formed the reading of their boyhood do not meet the response from me which they seem to expect.
