essentially immoral, is a question which has exercised the minds even of such writers as Montesquieu. “Espionage,” he says, “is never tolerable; if it were so it would be practised by honest men; but the necessary infamy of the person indicates the infamy of the thing.” This is in effect another version of the famous utterance of Argenson, who, reproached with employing as spies none but rogues and villains, exclaimed: “Find me honest men who will do this work.” The present prefecture of police believes it has found such men, and the discovery, if it has really been made, is a fortunate one indeed. Another variety of police spy to be met with in Paris is the officious volunteer spy. He may belong to the lower or to the higher ranks of society. He takes upon himself to observe and to denounce, without instructions, and solely in the hope of a pecuniary recompense. This variety is probably the most contemptible and the vilest. It should be mentioned, too, that the French capital swarms with invisible and unrecognisable spies, disguised, as they sometimes are, beneath an appearance of luxury or magnificence. This or that personage passes for a member of the diplomatic service. He is an admired figure in fashionable drawing-rooms, and while affecting to converse on the European situation, exercises the ear of a fox terrier and the eye of a hawk. Then, of course, there is the military spy, who is superior to the civil variety inasmuch as whilst the latter, in case of recognition, only incurs a more or less disagreeable misadventure, the former is liable to be shot. The military spy, therefore, may have all the heroism of the professed soldier. The civil spy system was naturally developed to an extraordinary degree by the subtle Richelieu. His secret agent took as many shapes as Proteus. Now it was a brave old seigneur, infirm and professedly deaf, in whose presence people would not hesitate to speak out and say everything, but who recovered his vigour and his legs in order to go and report to the cardinal a conversation of which he had not missed one detail. Now it was a woman, who, having insinuated herself into the intimate friendship of some young and brilliant courtier, wrested from him a dangerous and terrible secret. But it was not only throughout the length and breadth of France that Richelieu had spies; numbers of them were in his pay abroad, all over the Continent indeed, regularly reporting political intrigues, and furnishing clandestine copies of secret treaties. Enough, however, of the spy; let it simply be added that he has been introduced into two novels by Balzac, into one by Hugo, and into two by Alexandre Dumas, who has likewise made him figure in a couple of plays. * * * * * Let us pass from the most slinking and distasteful Paris character to the most open and, as many consider, the most charming one--from the “espion,” that is to say, to the “écuyère.”
