What was the mystery of Edwin Drood from Dickens's point of view we shall never know, except perhaps from Dickens in heaven, and then he will very likely have forgotten. But the mystery of Edwin Drood from our point of view, from that of his critics, and those who have with some courage (after his death) attempted to be his collaborators, is simply this. There is no doubt that Jasper either murdered Drood or supposed that he had murdered him. This certainty we have from the fact that it is the whole point of a scene between Jasper and Drood's lawyer Grewgious in which Jasper is struck down with remorse when he realises that Drood has been killed (from his point of view) needlessly and without profit. The only question is whether Jasper's remorse was as needless as his murder. In other words the only question is whether, while he certainly thought he had murdered Drood, he had really done it. It need hardly be said that such a doubt would not have been raised for nothing; gentlemen like Jasper do not as a rule waste good remorse except upon successful crime. The origin of the doubt about the real death of Drood is this. Towards the latter end of the existing chapters there appears very abruptly, and with a quite ostentatious air of mystery, a character called Datchery. He appears for the purpose of spying upon Jasper and getting up some case against him; at any rate, if he has not this purpose in the story he has no other earthly purpose in it. He is an old gentleman of juvenile energy, with a habit of carrying his hat in his hand even in the open air; which some have interpreted as meaning that he feels the unaccustomed weight of a wig. Now there are one or two people in the story who this person might possibly be. Notably there is one person in the story who seems as if he were meant to be something, but who hitherto has certainly been nothing; I mean Bazzard, Mr. Grewgious's clerk, a sulky fellow interested in theatricals, of whom an unnecessary fuss is made. There is also Mr. Grewgious himself, and there is also another suggestion, so much more startling that I shall have to deal with it later.
