Monsieur Daburon's office bore the number fifteen.
M.Daburon had arrived at his office in the Palais de Justice at nine o'clock in the morning, and was waiting.

His course resolved upon, he had not lost an instant, understanding as well as old Tabaret the necessity for rapid action.

He had already had an interview with the public prosecutor, and had arranged everything with the police.
Besides issuing the warrant against Albert, he had summoned the Count de Commarin, Madame Gerdy, Noel, and some of Albert's servants, to appear before him with as little delay as possible.
He thought it essential to question all these persons before examining the prisoner.

Several detectives had started off to execute his orders, and he himself sat in his office, like a general commanding an army, who sends off his aide-de-camp to begin the battle, and who hopes that victory will crown his combinations.
Often, at this same hour, he had sat in this office, under circumstances almost identical.

A crime had been committed, and, believing he had discovered the criminal, he had given orders for his arrest.
