“I—I—locked it in case burglars should get in while I was opening the front door,” stammered Firmin.

The millionaire turned the key, opened the door, and went into the hall. Germaine followed him. She threw off her dripping coat, and said with some heat: “I can’t conceive why you didn’t make sure that there was a train at a quarter to nine. I will not go to Paris to-night. Nothing shall induce me to take that midnight train!”

“Nonsense!” said the millionaire. “Nonsense—you’ll have to go! Where’s that infernal time-table?” He rushed to the table on to which he had thrown the time-table after looking up the train, snatched it up, and looked at the cover. “Why, hang it!” he cried. “It’s for June—June, 1903!”

“Oh!” cried Germaine, almost in a scream. “It’s incredible! It’s one of Jacques’ jokes!”

CHAPTER VIII
THE DUKE ARRIVES

The morning was gloomy, and the police-station with its bare, white-washed walls—their white expanse was only broken by notice-boards to which were pinned portraits of criminals with details of their appearance, their crime, and the reward offered for their apprehension—with its shabby furniture, and its dingy fireplace, presented a dismal and sordid appearance entirely in keeping with the September grey. The inspector sat at his desk, yawning after a night which had passed without an arrest. He was waiting to be relieved. The policeman at the door and the two policemen sitting on a bench by the wall yawned in sympathy.

The silence of the street was broken by the rattle of an uncommonly noisy motor-car. It stopped before the door of the police-station, and the eyes of the inspector and his men turned, idly expectant, to the door of the office.

It opened, and a young man in motor-coat and cap stood on the threshold.

He looked round the office with alert eyes, which took in everything, and said, in a brisk, incisive voice: “I am the Duke of Charmerace. I am here on behalf of M. Gournay-Martin. Last evening he received a letter from Arsène Lupin saying he was going to break into his Paris house this very morning.”

At the name of Arsène Lupin the inspector sprang from his chair, the policemen from their bench. On the instant they were wide awake, attentive, full of zeal.
