The Crystal Stopper, Maurice Leblanc [i can read books TXT] 📗

his entire confidence and acted as his private secretary, was the only one who knew of the retreat in the Rue Matignon. Now Gilbert was in prison. Was Lupin to suppose that Gilbert had betrayed him and put the police on his tracks? In that case, why were they content with taking the crystal stopper, instead of arresting him, Lupin?

But there was something much stranger still. Admitting that they had been able to force the doors of his flat⁠—and this he was compelled to admit, though there was no mark to show it⁠—how had they succeeded in entering the bedroom? He turned the key and pushed the bolt as he did every evening, in accordance with a habit from which he never departed. And, nevertheless⁠—the fact was undeniable⁠—the crystal stopper had disappeared without the lock or the bolt having been touched. And, although Lupin flattered himself that he had sharp ears, even when asleep, not a sound had waked him!

He took no great pains to probe the mystery. He knew those problems too well to hope that this one could be solved other than in the course of events. But, feeling very much put out and exceedingly uneasy, he then and there locked up his entresol flat in the Rue Matignon and swore that he would never set foot in it again.

And he applied himself forthwith to the question of corresponding with Vaucheray or Gilbert.

Here a fresh disappointment awaited him. It was so clearly understood, both at the Santé Prison and at the Law Courts, that all communication between Lupin and the prisoners must be absolutely prevented, that a multitude of minute precautions were ordered by the prefect of police and minutely observed by the lowest subordinates. Tried policemen, always the same men, watched Gilbert and Vaucheray, day and night, and never let them out of their sight.

Lupin, at this time, had not yet promoted himself to the crowning honour of his career, the post of chief of the detective-service,1 and, consequently, was not able to take steps at the Law Courts to insure the execution of his plans. After a fortnight of fruitless endeavours, he was obliged to bow.

He did so with a raging heart and a growing sense of anxiety.

“The difficult part of a business,” he often says, “is not the finish, but the start.”

Where was he to start in the present circumstances? What road was he to follow?

His thoughts recurred to Daubrecq the deputy, the original owner of the crystal stopper, who probably knew its importance. On the other hand, how was Gilbert aware of the doings and mode of life of Daubrecq the deputy? What means had he employed to keep him under observation? Who had told him of the place where Daubrecq spent the evening of that day? These were all interesting questions to solve.

Daubrecq had moved to his winter quarters in Paris immediately after the burglary at the Villa Marie-Thérèse and was now living in his own house, on the left-hand side of the little Square Lamartine that opens out at the end of the Avenue Victor-Hugo.

First disguising himself as an old gentleman of private means, strolling about, cane in hand, Lupin spent his time in the neighbourhood, on the benches of the square and the avenue. He made a discovery on the first day. Two men, dressed as workmen, but behaving in a manner that left no doubt as to their aims, were watching the deputy’s house. When Daubrecq went out, they set off in pursuit of him; and they were immediately behind him when he came home again. At night, as soon as the lights were out, they went away.

Lupin shadowed them in his turn. They were detective-officers.

“Hullo, hullo!” he said to himself. “This is hardly what I expected. So the Daubrecq bird is under suspicion?”

But, on the fourth day, at nightfall, the two men were joined by six others, who conversed with them in the darkest part of the Square Lamartine. And, among these new arrivals, Lupin was vastly astonished to recognize, by his figure and bearing, the famous Prasville, the erstwhile barrister, sportsman and explorer, now favourite at the Élysée, who, for some mysterious reason, had been pitchforked into the headquarters of police as secretary-general, with the reversion of the prefecture.

And, suddenly, Lupin remembered: two years ago, Prasville and Daubrecq the deputy had had a personal encounter on the Place du Palais-Bourbon. The incident made a great stir at the time. No one knew the cause of it. Prasville had sent his seconds to Daubrecq on the same day; but Daubrecq refused to fight.

A little while later, Prasville was appointed secretary-general.

“Very odd, very odd,” said Lupin, who remained plunged in thought, while continuing to observe Prasville’s movements.

At seven o’clock Prasville’s group of men moved away a few yards, in the direction of the Avenue Henri-Martin. The door of a small garden on the right of the house opened and Daubrecq appeared. The two detectives followed close behind him and, when he took the Rue-Taitbout train, jumped on after him.

Prasville at once walked across the square and rang the bell. The garden-gate was between the house and the porter’s lodge. The portress came and opened it. There was a brief conversation, after which Prasville and his companions were admitted.

“A domiciliary visit,” said Lupin. “Secret and illegal. By the strict rules of politeness, I ought to be invited. My presence is indispensable.”

Without the least hesitation he went up to the house, the door of which had not been closed, and, passing in front of the portress, who was casting her eyes outside, he asked, in the hurried tones of a person who is late for an appointment:

“Have the gentlemen come?”

“Yes, you will find them in the study.”

His plan was quite simple: if anyone met him, he would pretend to be a tradesman. But there was no need for this subterfuge. He was able, after crossing an empty hall, to enter a
