It would be unfair, however, to accuse the Germans of monopolising all those vicious characteristics which go to form the complete spy. Indeed, it would probably be nearer the mark to declare that it is only because of the elaborate excellence of the German organisation that the Teuton has signalised himself so prominently these later times in espionage. For, in truth, the Teutonic mind is fundamentally lacking, it is well known, in those qualities of craft and imagination which produce the best kind of secret service agent. Perseverance and the philosophy which knows how to wait on circumstances, these conventional enough qualities he undoubtedly possesses in a marked degree above his fellows. Nevertheless, they are not the most important requirements of the master-spy, whose base diplomacy and its results must depend to a great extent upon the exercise of constructive imagination and the forcing of circumstances to suit his particular strategy. The German has excelled his congeners at the business in the opinion of modern men solely for the reason that among the Germans the trade of the spy is not accounted more dishonourable than any other. In all probability, however, the Italian, the Greek, the Kelt, given a highly systematised school and an equal ethical standpoint, would prove abler executants in any mission which called for the employment of deep-set guile, the power of divining motives and the ability to calculate the effect of moves. The essential arts of the diplomatist—has not an ambassador been described as an official spy?—underlie, in respect of the mental operations required, the work of your successful secret service agent, and although men like Bismarck, whose mentality was not of a positively Teutonic cast, may be cited in disproof of the statement, it is certain that the German mind is less adapted and less adaptable to the fine processes of the arts of political negotiation than that of either the Kelt or the Italian.
