Regarding the chapters in this book which recount actual experiences of Secret Service work, I can assure my readers that nothing has been divulged which touches even the fringe of the important secrets that every Secret Service agent would proudly guard with his life. Those things are sacred and would never be intentionally divulged. On the other hand the records of adventure are not mere efforts at fiction. They are actual experiences, faintly tinted, maybe, in _couleur de rose_ to raise bald facts into readable narrative. They are also scenes which are enacted every day on the stage of Life's Theatre, often much nearer to the circle in which the reader moves than he or she may realise, imagine, or dream about. They are given in order the better to excite interest, to exemplify the work which has to be done, and which in the future may still require attention. Needless to add that a book of this description has not been permitted to go to press without difficulties. Much more has been left unsaid than is said. Much has of necessity been omitted, not only for the sake of the maintenance of the glory of one's own beloved land, but also for the sake of the personal future safety and well-being of others besides oneself. Some of the readers of the MS., through whose hands it had to pass before publication, have commented upon the political amalgam which has been introduced into the book as not being strictly within the scope of its title. If any apology is due under this head the author can only plead justification by reason of his deep and earnest desire for reform both abroad and at home. In his humble opinion the evils that he exposes or hints at could not have been brought home to his readers had he confined himself entirely to the perhaps more interesting narrative of individual adventure. So far as the statistics given regarding the blockade leakages are concerned, he feels they are important enough to carry historical interest, and should therefore be collated and put on permanent record. Secret Service agents devoted much time and attention to these details, and our then Government was or should have been fully alive to the fact that the so-called blockade was only a ridiculous sham, long before the _Daily Mail_ campaign opened. Why our Government made no effort to checkmate, stop, or divert these extraordinary supplies going direct into the enemy country, is left to the judgment of my readers.
