I confess that I trembled. I knew well that the king, particular in small courtesies, never forgot to call his servants by their correct titles, save in two cases; when he indicated by the seeming error, as once in Marshal Biron's affair, his intention to promote or degrade them; or when he was moved to the depths of his nature and fell into an old habit. I did not dare to reply, but listened greedily for more information. "When is it to be done?" asked the innkeeper, sinking his voice and glancing round, as if he would call especial attention to this. "That depends upon Master la Rivière," the girl answered. "To-morrow night, I understand, if Master la Rivière can have the stuff ready." I met the king's eyes. They shone fiercely in the faint light, which issuing from the window fell on him. Of all things he hated treachery most, and La Rivière was his first body physician, and at this very time, as I well knew, was treating him for a slight derangement which the king had brought upon himself by his imprudence. This doctor had formerly been in the employment of the Bouillon family, who had surrendered his services to the king. Neither I nor his majesty had trusted the Duke of Bouillon for the last year past, so that we were not surprised by this hint that he was privy to the design. Despite our anxiety not to miss a word, an approaching step warned us at this moment to draw back. More than once before we had done so to escape the notice of a wayfarer passing up and down. But this time I had a difficulty in inducing the king to adopt the precaution. Yet it was well that I succeeded, for the person who came stumbling along toward us did not pass, but, mounting the steps, walked by within touch of us and entered the house. "The plot thickens," muttered the king. "Who is this?" At the moment he asked I was racking my brain to remember. I have a good eye and a fair recollection for faces, and this was one I had seen several times. The features were so familiar that I suspected the man of being a courtier in disguise, and I ran over the names of several persons whom I knew to be Bouillon's secret agents. But he was none of these, and obeying the king's gesture, I bent myself again to the task of listening. The girl looked up on the man's entrance, but did not rise. "You are late, Martin," she said. "A little," the newcomer answered. "How do you do, Master Andrew? What cheer? What, still vexing, mistress?" he added contemptuously to the girl. "You have too soft a heart for this business!" She sighed, but made no answer. "You have made up your mind to it, I hear?" said the innkeeper. "That is it. Needs must when the devil drives!" replied the man jauntily. He had a downcast, reckless, luckless air, yet in his face I thought I still saw traces of a better spirit. "The devil in this case was Epernon," quoth Andrew.
