Nothing now remained except to collect the different objects which would be useful for the prosecution, and might at a later period confound the culprit. Old Tabaret examined with extreme care the dead woman’s finger-nails; and, using infinite precaution, he even extracted from behind them several small particles of kid. The largest of these pieces was not above the twenty-fifth part of an inch in length; but all the same their colour was easily distinguishable. He put aside also the part of the dress upon which the assassin had wiped his weapon. These with the bundle recovered from the Seine, and the different casts taken by the old fellow, were all the traces the murderer had left behind him.

It was not much; but this little was enormous in the eyes of M. Daburon; and he had strong hopes of discovering the culprit. The greatest obstacle to success in the unravelling of mysterious crimes is in mistaking the motive. If the researches take at the first step a false direction, they are diverted further and further from the truth, in proportion to the length they are followed. Thanks to old Tabaret, the magistrate felt confident that he was in the right path.

Night had come on. M. Daburon had now nothing more to do at La Jonchere; but Gevrol, who still clung to his own opinion of the guilt of the man with the rings in his ears, declared he would remain at Bougival. He determined to employ the evening in visiting the different wine shops, and finding if possible new witnesses. At the moment of departure, after the commissary and the entire party had wished M. Daburon good-night, the latter asked M. Tabaret to accompany him.

“I was about to solicit that honour,” replied the old fellow. They set out together; and naturally the crime which had been discovered, and with which they were mutually preoccupied, formed the subject of their conversation.

“Shall we, or shall we not, ascertain the antecedents of this woman!” repeated old Tabaret. “All depends upon that now!”

“We shall ascertain them, if the grocer’s wife has told the truth,” replied M. Daburon. “If the husband of Widow Lerouge was a sailor, and if her son Jacques is in the navy, the minister of marine can furnish information that will soon lead to their discovery. I will write to the minister this very night.”

They reached the station at Rueil, and took their places in the train. They were fortunate enough to secure a 1st class carriage to themselves. But old Tabaret was no longer disposed for conversation. He reflected, he sought, he combined; and in his face might easily be read the working of his thoughts. M. Daburon watched him curiously and felt singularly attracted by this eccentric old man, whose very original taste had led him to devote his services to the secret police of the Rue de Jerusalem.

“M Tabaret,” he suddenly asked, “have you been long associated with the police?”

“Nine years, M. Daburon, more than nine years; and permit me to confess I am a little surprised that you have never before heard of me.”

“I certainly knew you by reputation,” answered M. Daburon; “but your name did not occur to me, and it was only in consequence of hearing you praised that I had the excellent idea of asking your assistance. But what, I should like to know, is your reason for adopting this employment?”
