“Yes, monsieur, the lady lived here for five years without ever going out, and more by token, her lover, desperately jealous though she was beyond reproach, took the greatest precautions when he came in or went out.  And a very handsome young man he was too!”

Lucien was at this time still staying with his sister, Madame Sechard; but as soon as he returned, Contenson sent the porter to the Quai Malaquais to ask Monsieur de Rubempre whether he were willing to part with the furniture left in the rooms lately occupied by Madame van Bogseck.  The porter then recognized Lucien as the young widow’s mysterious lover, and this was all that Contenson wanted.  The deep but suppressed astonishment may be imagined with which Lucien and Carlos received the porter, whom they affected to regard as a madman; they tried to upset his convictions.

Within twenty-four hours Carlos had organized a force which detected Contenson red-handed in the act of espionage.  Contenson, disguised as a market-porter, had twice already brought home the provisions purchased in the morning by Asie, and had twice got into the little mansion in the Rue Saint-Georges.  Corentin, on his part, was making a stir; but he was stopped short by recognizing the certain identity of Carlos Herrera; for he learned at once that this Abbe, the secret envoy of Ferdinand VII., had come to Paris towards the end of 1823.  Still, Corentin thought it worth while to study the reasons which had led the Spaniard to take an interest in Lucien de Rubempre.  It was soon clear to him, beyond doubt, that Esther had for five years been Lucien’s mistress; so the substitution of the Englishwoman had been effected for the advantage of that young dandy.

Now Lucien had no means; he was rejected as a suitor for Mademoiselle de Grandlieu; and he had just bought up the lands of Rubempre at the cost of a million francs.

Corentin very skilfully made the head of the General Police take the first steps; and the Prefet de Police a propos to Peyrade, informed his chief that the appellants in that affair had been in fact the Comte de Serizy and Lucien de Rubempre.

“We have it!” cried Peyrade and Corentin.

The two friends had laid plans in a moment.

“This hussy,” said Corentin, “has had intimacies; she must have some women friends.  Among them we shall certainly find one or another who is down on her luck; one of us must play the part of a rich foreigner and take her up.  We will throw them together.  They always want something of each other in the game of lovers, and we shall then be in the citadel.”
