Picquart's Investigations
At first Picquart did not establish any connection in his own mind between the "petit bleu" and the bordereau; he simply thought he was on the track of a fresh traitor, and hoped to catch him in the act. However, Esterhazy had been warned, and not only was it impossible to surprise him in any compromising visit, but he showed himself openly at the German embassy, to which he went to ask for a passport for his colonel. He insisted that he be allowed to return to the War Office, in preference to the Intelligence Department, and was able to attain the post through the highest parliamentary and military influence.
However, a fresh incident occurred to strengthen Picquart's suspicions. The French military attaché at Berlin, Foucault, informed him of a curious conversation he had had with Richard Cuers, a spy who wavered between France and Germany. Cuers told Foucault that Germany had never employed Dreyfus, that the only French officer who was in Germany's pay was a major of infantry who had furnished some sheets from lectures held at the shooting school at Châlons.
