Sigismond Trottier was at least sixty years of age, tall, spare to attenuation, with a long narrow face of almost livid pallor, and long gray hair, falling over a greasy olive-green velvet collar, choice ornament of a threadbare and faded olive-green frock-coat. His jaw was narrow and projecting, his lips were thin and pinched, his nose was long and sharp, his eyebrows were gray and shaggy. The only features that gave life or colour to the face were the restless and brilliant black eyes, small, keen, observant, the eyes of a creature always on the watch. Ah, how many of the darkest mysteries of Paris had that keen glance discovered, how many a loathsome depth had that ruthless gaze explored, how many a social ulcer, how many a domestic disease, how many a wound of heart and honour, how many an atrophy of purse and reputation had those eyes pierced and scrutinised, while all the rest of the world was still blind to the coming ruin, the inevitable disgrace! Sigismond Trottier was a student of society. It was his boast that he knew this Paris of the Third Republic as well as Saint-Simon knew the Paris of the great Louis; knew it in all its strength; and in all its weakness; knew it to the core of its rotten heart. Needless to say that such a man was invaluable as a paragraphist. He had the same keen scent for a scandal that the well-trained detective has for a crime. A whisper, a shrug was enough to put him on the right track. He was a genius at that modern style of hint and innuendo which just stops short of libel. He had killed more reputations than any man in Paris: and he had never been to prison. His safety lay in the keenness of his perception, which never allowed him to fall into such mistakes as have ruined other society gossips. Whatever Sigismond Trottier wrote was true. He had an extraordinary power of winnowing the chaff from the corn in the floating scandals of the Boulevard. He knew what to accept and what to reject. His judgment was infallible. When Parisian society saw the hint of an elopement, the suggestion of a marital wrong signed by Sigismond's hieroglyphic--an Egyptian beetle--the thing was received as a fact. The pen of the unerring recorder had proclaimed a truth. Happily he was not a physical coward, though a professional assailant of man's honour and woman's reputation. He had given good proof of his courage on several occasions, had stood up before famous swordsmen, had faced marksmen of repute. That deep dint in his lean and livid cheek was the mark of a bullet from the Duke of Midlothian's pistol--that famous _viveur_ who expired suddenly amidst the fading flowers and flaring tapers of a Boulevard supper-room--the very spirit of profligate pleasure extinguished in a breath. That long slanting scar upon the left jaw, a shade more livid than the normal lividity of the complexion, was the result of five minutes' sword-play between the Boulevard chronicler and the Marquis du
