visitor from America informed me that all sorts of revolutionary refugees in New York would have it that the book was written by somebody who knew a lot about them. This seemed to me a very high compliment, considering that, as a matter of hard fact, I had seen even less of their kind than the omniscient friend who gave me the first suggestion for the novel. I have no doubt, however, that there had been moments during the writing of the book when I was an extreme revolutionist, I won't say more convinced than they but certainly cherishing a more concentrated purpose than any of them had ever done in the whole course of his life. I don't say this to boast. I was simply attending to my business. In the matter of all my books I have always attended to my business. I have attended to it with complete self-surrender. And this statement, too, is not a boast. I could not have done otherwise. It would have bored me too much to make-believe. The suggestions for certain personages of the tale, both law-abiding and lawless, came from various sources which, perhaps, here and there, some reader may have recognized. They are not very recondite. But I am not concerned here to legitimize any of those people, and even as to my general view of the moral reactions as between the criminal and the police all I will venture to say is that it seems to me to be at least arguable. The twelve years that have elapsed since the publication of the book have not changed my attitude. I do not regret having written it. Lately, circumstances, which have nothing to do with the general tenor of this Preface, have compelled me to strip this tale of the literary robe of indignant scorn it has cost me so much to fit on it decently, years ago. I have been forced, so to speak, to look upon its bare bones. I confess that it makes a grisly skeleton. But still I will submit that telling Winnie Verloc's story to its anarchistic end of utter desolation, madness and despair, and telling it as I have told it here, I have not intended to commit gratuitous outrage on the feelings of mankind.
