Modern spies of the professional type, more especially those employed by Germany, fully meet the specifications of Napoleon's idea of the race. The accomplished spy of to-day is invariably a man of at least quasi-criminal proclivities, a being entirely lacking in a moral sense, a degenerate briefly; and indeed experts in the secret history of the German special-information departments all agree in declaring that a "white man," to use an Americanism, is worse than useless to the experts at the chief bureau of the Berlin Secret Service. As a consequence, their _corps d'élite_ is mostly made up of men who, if they have not known the inside of prisons, have at least earned an unequivocal right to such knowledge. One of the profoundest technicians in the business of organising spy campaigns, the late Karl Stieber, has stated that the most valuable spy is your born aristocrat with a bad record and a worse reputation. Proof of the soundness of this view would seem to have been fully advanced by the noble interveners in the Dreyfus case, and, in any event, it is known that among the names of the organising staff of Berlin's school for spies, a large number are those who bear the names of famous families, while the remainder, if not all gentlemen by birth, are at least gentlemen by act of parliament, as the saying is. Courage, _aplomb_, the possession of what Americans so aptly term "a good front," easy manners and a genial temperament—of any or all of these qualifications, a man of good birth is only in rare cases devoid. Heredity alone has given him many of the psychic requirements that go to make up the most valuable of actors in a desperate situation, including, perhaps, that philosophy of absolute _insouciance_ which makes of him the most sinister and cold-blooded of all criminal agents.
