“I start for Paris at full speed at five o’clock to-morrow morning. I need not tell you that from this moment I shall devote myself to the business of which you have spoken to me, nor need I add that this devotion is entirely disinterested. If I had not already proved those two things to you, I should not be the man you require. But, just because I feel that I _have_ the head and the heart necessary for your enterprise, I tell you frankly that it can only be carried out at great expense. The business of getting information--which is only a preparatory measure--is made difficult, if not impossible, unless a considerable sum of money can be spent.... I believe myself authorized to speak to you in this way, because I have the advantage--rare enough amongst men--of being above suspicion with regard to my own interests.”[39] On Wednesday, December 19, d’Auerweck entered Paris, and put up at a hotel in the Rue Coq-Héron, where he gave his name as Scheltheim. He instantly set to work to get the letters he had brought with him delivered at their addresses, and to make certain of the co-operation which was essential to him. But there was a disappointment in store; Goguelat, upon whom so much depended, was away from Paris, and, as it happened, in London. It was necessary to act without him, and this was no easy matter. The excitement caused by the trial of the King enforced upon the plotters a redoubled caution. D’Auerweck got uneasy when he found no letters coming from Peltier in answer to his own. He went more frequently to Versailles, and to Saint-Germain, and kept on begging for funds. On December 25, the day before M. de Sèze was to present the King’s defence to the Convention, d’Auerweck wrote to Peltier-- “The persons (you know whom I mean) do not care to arrive here before Thursday, which is very natural, for there is all sorts of talk as to what may happen to-morrow.... You promised me to write by each post; but there can be no doubt that you forgot me on Tuesday, the 18th, for otherwise I must have had your letters by this time. One thing I cannot tell you too often: it is that I consider it essential to take to you in person any documents that I may be able to procure.”[40] The documents in question were those which Peltier had alluded to, some days before, in a letter to Lady Atkyns: “I heard to-day that there was some one in Paris who had all the plans that you want in the greatest detail;”[41] and at the end of the month he returned to the subject-- “I am expecting, too, a most exact plan of the Temple Prison, taken in November; and not only of the Temple, but also of the caves that lie under the tower--caves that are not generally known of, and which were used from time immemorial for the burial of the ancient Templars. I know a place where the wall is only eighteen inches thick, and debouches on the next street.”
