"You guess rightly," he said with a smile. "I was in the crowd and marked you enter, and a soldier standing next to me observed to a comrade that he had heard that Burgundy had sent the herald to demand the surrender of a castle held by one Sir Eustace, a knight who was known to have friendly leanings towards the English, being a vassal of their king for estates that had come to him with an English wife, and that doubtless this was the lady. When my eye fell on you in the crowd I said: Here is a youth of shrewdness and parts, he is alone and is a foreigner, and maybe I can be of service to him; therefore I shot my shaft, and, as you see, with success. I said to myself: This youth, being a stranger, will know of no one to whom he can turn for information, and I can furnish him with almost any that he may require. I come in contact with the highest and the lowest, for the Parisians are credulous, and after dark there are some of rank and station who come to my doors for filtres and nostrums, or to have their horoscope cast and their futures predicted. You will ask why one who has such clients should condescend to stand at a booth and talk to this rabble; but it has its purpose. Were I known only as one whom men and women visit in secret, I should soon become suspected of black arts, the priests would raise an outcry against me, and one of these days I might be burned. Here, however, I ostensibly earn my living as a mountebank vendor of drugs and nostrums, and therefore no one troubles his head about me."
