Danville’s intention, in sending his letter to Paris, had been simply to save himself by patriotic bluster. He was thunderstruck at receiving a reply, taking him at his word, and summoning him to the capital to accept employment there under the then existing Government. There was no choice but to obey. So to Paris he journeyed, taking his wife with him into the very jaws of danger. He was then at open enmity with Trudaine; and the more anxious and alarmed he could make the brother feel on the sister’s account, the better he was pleased. True to his trust and his love, through all dangers as through all persecutions, Trudaine followed them; and the street of their sojourn at Paris, in the perilous days of the Terror, was the street of his sojourn too. Danville had been astonished at the acceptance of his proffered services; he was still more amazed when he found that the post selected for him was one of the superintendent’s places in that very office of Secret Police in which Lomaque was employed as agent. Robespierre and his colleagues had taken the measure of their man--he had money enough, and local importance enough to be worth studying. They knew where he was to be distrusted, and how he might be made useful. The affairs of the Secret Police were the sort of affairs which an unscrupulously cunning man was fitted to help on; and the faithful exercise of that cunning in the service of the State was insured by the presence of Lomaque in the office. The discarded servant was just the right sort of spy to watch the suspected master. Thus it happened that, in the office of the Secret Police at Paris, and under the Reign of Terror, Lomaque’s old master was, nominally, his master still--the superintendent to whom he was ceremonially accountable, in public--the suspected man, whose slightest words and deeds he was officially set to watch, in private. Ever sadder and darker grew the face of Lomaque as he now pondered alone over the changes and misfortunes of the past five years. A neighboring church-clock striking the hour of seven aroused him from his meditations. He arranged the confused mass of papers before him--looked toward the door, as if expecting some one to enter--then, finding himself still alone, recurred to the one special paper which had first suggested his long train of gloomy thoughts. The few lines it contained were signed in cipher, and ran thus: “You are aware that your superintendent, Danville, obtained leave of absence last week to attend to some affairs of his at Lyons, and that he is not expected back just yet for a day or two. While he is away, push on the affair of Trudaine. Collect all the evidence, and hold yourself in readiness to act on it at a moment’s notice. Don’t leave the office till you have heard from me again. If you have a copy of the Private Instructions respecting Danville, which you wrote for me, send it to my house. I wish to refresh my memory. Your original letter is burned.”
