A few nights later than the one on which the murderer, Fordingbridge, had been taken to the prison, Bertie Elphinston, riding up to the northern gate of Paris, demanded admission. It was a cold, raw night this--one of those October evenings common enough to the north of France, when the moisture hangs like rain-drops on every bush and bramble, and when the rawness penetrates to the inside of man, making him think of drams of brandy and Nantz as the best preventive of chill and cold. He would not have ridden in to-night, would not have left the comfortable fire in the officers' quarters of the St. Denis Caserne to splash through six miles of wet roads, only it was Thursday, the day on which he invariably went to Paris, partly to pay his respects to Charles Edward, partly to see his mother and Kate. Also, if he did not come on Thursday there was no other opportunity for him to do so for a week; there were only the officers of two troops quartered in the old town, and but one night a week granted to each for leave. Therefore he was loath to lose his turn, and to go a whole fortnight without seeing the two creatures dearest to him in the world. "A rough, raw night," he said to the man at the gate as he passed in, "a night better for indoor pleasures than the streets. You have the best of it," glancing in at the bright fire in the man's room, "much the best of it." "_Mais out, Monsieur le Capitaine_," said the custodian--who knew him very well--following his glance as it rested on the blazing hearth and his little girl playing with a pup before it. "_Mais oui_." Then he said, as Bertie stooped down to tighten the buckle of his stirrup leather, "Was monsieur expecting, _par hazard_, to meet anyone hereabouts to-night? Any friend or person with a message?" "No," replied Elphinston, partly in answer to his question, partly in surprise. "No one. Why do you ask?" The man shrugged his shoulders in the true French manner, then he said: "Oh, for no serious reason--but," and he paused and then went on again: "There came yesterday an unknown one to me who asked how often Monsieur le Capitaine Elphinston rode into Paris. I knew not your name then, monsieur, but his description was graphic, very graphic, so that at once I knew he meant you. Moreover, the other officers of monsieur's regiment come not so regularly on any day, some come not at all." "'Tis strange," Bertie said; "I know no one who need ask for me in this mysterious manner, especially as there is no mystery about me. My life is simple and open enough, I should suppose. Six days a week in garrison at St. Denis, one night a week in Paris; there is not much to hide."
