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 Arsene Lupin saying he was going to break into his Paris house this very morning."
At the name of Arsene Lupin the inspector sprang from his chair, the policemen from their bench. On the instant they were wide awake, attentive, full of zeal.
"The letter, your Grace!" said the inspector briskly.
The Duke pulled off his glove, drew the letter from the breast-pocket of his under-coat, and handed it to the inspector.
The inspector glanced through it, and said. "Yes, I know the handwriting well." Then he read it carefully, and added, "Yes, yes: it's his usual letter."
"There's no time to be lost," said the Duke quickly. "I ought to have been here hours ago—hours. I had a break-down. I'm afraid I'm too late as it is."
"Come along, your Grace—come along, you," said the inspector briskly.
The four of them hurried out of the office and down the steps of the police-station. In the roadway stood a long grey racing-car, caked with muds—grey mud, brown mud, red mud—from end to end. It looked as if it had brought samples of the soil of France from many districts.
"Come along; I'll take you in the car. Your men can trot along beside us," said the Duke to the inspector.
He slipped into the car, the inspector jumped in and took the seat beside him, and they started. They went slowly, to allow the two policemen to keep up with them. Indeed, the car could not have made any great pace, for the tyre of the off hind-wheel was punctured and deflated.
In three minutes they came to the Gournay-Martin house, a wide-fronted mass of undistinguished masonry, in an undistinguished row of exactly the same pattern. There were no signs that any one was living in it. Blinds were drawn, shutters were up over all the windows, upper and lower. No smoke came from any of its chimneys, though indeed it was full early for that.
Pulling a bunch of keys from his pocket, the Duke ran up the steps. The inspector followed him. The Duke looked at the bunch, picked out the latch-key, and fitted it into the lock. It did not open it. He drew it out and tried another key and another. The door remained locked.
"Let me, your Grace," said the inspector. "I'm more used to it. I shall be quicker."
The Duke handed the keys to him, and, one after another, the inspector fitted them into the lock. It was useless. None of them opened the door.
"They've given me the wrong keys," said the Duke, with some vexation. "Or no—stay—I see what's happened. The keys have been changed."
"Changed?" said the inspector. "When? Where?"
"Last night at Charmerace," said the Duke. "M. Gournay-Martin declared that he saw a burglar slip out of one of the windows of the hall of the chateau, and we found the lock of the bureau in which the keys were kept broken."
The inspector seized the knocker, and hammered on the door.
"Try that door there," he cried to his men, pointing to a side-door on the right, the tradesmen's entrance, giving access to the back of the house. It was locked. There came no sound of movement in the house in answer to the inspector's knocking.
"Where's the concierge?" he said.
The Duke shrugged his shoulders. "There's a housekeeper, too—a woman named Victoire," he said. "Let's hope we don't find them with their throats cut."
"That isn't Lupin's way," said the inspector. "They won't have come to much harm."
"It's not very likely that they'll be in a position to open doors," said the Duke drily.
"Hadn't we better have it broken open and be done with it?"
The inspector hesitated.
"People don't like their doors broken open," he said. "And M. Gournay-Martin—"
"Oh, I'll take the responsibility of that," said the Duke.
"Oh, if you say so, your Grace," said the inspector, with a brisk relief. "Henri, go to Ragoneau, the locksmith in the Rue Theobald. Bring him here as quickly as ever you can get him."
"Tell him it's a couple of louis if he's here inside of ten minutes," said the Duke.
The policeman hurried off. The inspector bent down and searched the steps carefully. He searched the roadway. The Duke lighted a cigarette and watched him. The house of the millionaire stood next but one to the corner of a street which ran at right angles to the one in which it stood, and the corner house was empty. The inspector searched the road, then he went round the corner. The other policeman went along the road, searching in the opposite direction. The Duke leant against the door and smoked on patiently. He showed none of the weariness of a man who has spent the night in a long and anxious drive in a rickety motor-car. His eyes were bright and clear; he looked as fresh as if he had come from his bed after a long night's rest. If he had not found the South Pole, he had at any rate brought back fine powers of endurance from his expedition in search of it.
The inspector came back, wearing a disappointed air.
"Have you found anything?" said the Duke.
"Nothing," said the inspector.
He came up the steps and hammered again on the door. No one answered his knock. There was a clatter of footsteps, and Henri and the locksmith, a burly, bearded man, his bag of tools slung over his shoulder, came hurrying up. He was not long getting to work, but it was not an easy job. The lock was strong. At the end of five minutes he said that he might spend an hour struggling with the lock itself; should he cut away a piece of the door round it?
"Cut away," said the Duke.
The locksmith changed his tools, and in less than three minutes he had cut away a square piece from the door, a square in which the lock was fixed, and taken it bodily away.
The door opened. The inspector drew his revolver, and entered the house. The Duke followed him. The policemen drew their revolvers, and followed the Duke. The big hall was but dimly lighted. One of the policemen quickly threw back the shutters of the windows and let in the light. The hall was empty, the furniture in perfect order; there were no signs of burglary there.
"The concierge?" said the inspector, and his men hurried through the little door on the right which opened into the concierge's rooms. In half a minute one of them came out and said: "Gagged and bound, and his wife too."
"But the rooms which were to be plundered are upstairs," said the Duke—"the big drawing-rooms on the first floor. Come on; we may be just in time. The scoundrels may not yet have got away."
He ran quickly up the stairs, followed by the inspector, and hurried along the corridor to the door of the big drawing-room. He threw it open, and stopped dead on the threshold. He had arrived too late.
The room was in disorder. Chairs were overturned, there were empty spaces on the wall where the finest pictures of the millionaire had been hung. The window facing the door was wide open. The shutters were broken; one of them was hanging crookedly from only its bottom hinge. The top of a ladder rose above the window-sill, and beside it, astraddle
