THE murder of M. Rovère, committed in broad daylight, in a quarter of Paris filled with life and movement, caused a widespread sensation. There was so much mystery mixed in the affair. What could be ascertained about the dead man's life was very dramatically written up by Paul Rodier in a sketch, and this, republished everywhere and enlarged upon, soon gave to the crime of the Boulevard de Clichy the interest of a judicial romance. All that there was of vulgar curiosity in man awoke, as atavistic bestiality at the smell of blood. What was this M. Rovère, former Consul to Buenos Ayres or Havana, amateur collector of objects of virtu, member of the Society of Bibliophiles, where he had not been seen for a long time? What enemy had entered his room for the purpose of cutting his throat? Might he not have been assassinated by some thief who knew that his rooms contained a collection of works of art? The fête at Montmartre was often in full blast in front of the house where the murder had been committed, and among the crowd of ex-prison birds and malefactors who are always attendant upon foreign kirmesses might not some one of them have returned and committed the crime? The papers took advantage of the occasion to moralize upon permitting these fêtes to be held in the outlying boulevards, where vice and crime seemed to spring spontaneously from the soil. But no one, not one journal--perhaps by order--spoke of that unknown visitor whom Moniche called _the individual_, and whom the portress had seen standing beside M. Rovère in front of the open safe. Paul Rodier in his sketch scarcely referred to the fact that justice had a clew important enough to penetrate the mystery of the crime, and in the end arrest the murderer. And the readers while awaiting developments asked what mystery was hidden in this murder. Moniche at times, wore a frightened yet important air. He felt that he was an object of curiosity to many, the centre of prejudices. The porter and his wife possessed a terrible secret. They were raised in their own estimation. "We shall appear at the trial," said Moniche, seeing himself already before the red robes, and holding up his hand to swear that he would tell the truth, the whole truth and nothing but the truth. And as they sat together in their little lodge they talked the matter over and over, and brought up every incident in M. Rovère's life which might have a bearing on the case. "Do you remember the young man who came one day and insisted on seeing Monsieur le Consul?" "Ah! Very well, indeed," said Moniche. "I had forgotten that one. A felt hat, his face bronzed, and a droll accent. He had come from away off somewhere. He was probably a Spaniard." "Some beggar, likely. A poor devil whom the Consul had known in America, in the Colonies, one knows not where."
