Lupin showed his bound hands:
"It will be a tough battle. Can I fight like this?"
The Emperor said to the count:
"Unfasten him.... And keep me informed."
In this way, by a sudden effort, bringing the hateful vision of the murder into the discussion, boldly, without evidence, Arsène Lupin gained time and resumed the direction of the search:
"Sixteen hours still," he said to himself, "it's more than I want."
HE REACHED the premises occupied by Isilda, at the end of the old out-buildings. These buildings served as barracks for the two hundred soldiers guarding the ruins; and the whole of this, the left wing, was reserved for the officers.
Isilda was not there. The count sent two of his men to look for her. They came back. No one had seen the girl.
Nevertheless, she could not have left the precincts of the ruins. As for the Renascence palace, it was, so to speak, invested by one-half of the troops; and no one was able to obtain admittance.
At last, the wife of a subaltern who lived in the next house declared that she had been sitting at her window all day and that the girl had not been out.
"If she hadn't gone out," said Waldemar, "she would be here now: and she is not here."
Lupin observed:
"Is there a floor above?"
"Yes, but from this room to the upper floor there is no staircase."
"Yes, there is."
He pointed to a little door opening on a dark recess. In the shadow, he saw the first treads of a staircase as steep as a ladder.
"Please, my dear count," he said to Waldemar, who wanted to go up, "let me have the honor."
"Why?"
"There's danger."
He ran up and at once sprang into a low and narrow loft. A cry escaped him:
"Oh!"
"What is it?" asked the count, emerging in his turn.
"Here.... on the floor.... Isilda...."
He knelt down beside the girl, but, at the first glance, saw that she was simply stunned and that she bore no trace of a wound, except a few scratches on the wrists and hands. A handkerchief was stuffed into her mouth by way of a gag.
"That's it," he said. "The murderer was here with her. When we came, he struck her a blow with his fist and gagged her so that we should not hear her moans."
"But how did he get away?"
"Through here.... look.... there is a passage connecting all the attics on the first floor."
"And from there?"
"From there, he went down the stairs of one of the other dwellings."
"But he would have been seen!"
"Pooh, who knows? The creature's invisible. Never mind! Send your men to look. Tell them to search all the attics and all the ground-floor lodgings."
He hesitated. Should he also go in pursuit of the murderer?
But a sound brought him back to the girl's side. She had got up from the floor and a dozen pieces of gold money had dropped from her hands. He examined them. They were all French.
"Ah," he said, "I was right! Only, why so much gold? In reward for what?"
Suddenly, he caught sight of a book on the floor and stooped to pick it up. But the girl darted forward with a quicker movement, seized the book and pressed it to her bosom with a fierce energy, as though prepared to defend it against any attempt to take hold of it.
"That's it," he said. "The money was offered her for the book, but she refused to part with it. Hence the scratches on the hands. The interesting thing would be to know why the murderer wished to possess the book. Was he able to look through it first?"
He said to Waldemar:
"My dear count, please give the order."
Waldemar made a sign to his men. Three of them threw themselves on the girl and, after a hard tussle, in which the poor thing stamped, writhed and screamed with rage, they took the volume from her.
"Gently, child," said Lupin, "be calm.... It's all in a good cause.... Keep an eye on her, will you? Meanwhile, I will have a look at the object in dispute."
It was an odd volume of Montesquieu's Voyage au temple de Guide, in a binding at least a century old. But Lupin had hardly opened it before he exclaimed:
"I say, I say, this is queer! There is a sheet of parchment stuck on each right hand page; and those sheets are covered with a very close, small handwriting."
He read, at the beginning:
"Diary of the Chevalier Gilles de Malrêche, French servant to His Royal Highness the Prince of Zweibruckenveldenz, begun in the Year of Our Lord 1794."
"What! Does it say that?" asked the count.
"What surprises you?"
"Isilda's grandfather, the old man who died two years ago, was called Malreich, which is the German form of the same name."
"Capital! Isilda's grandfather must have been the son or the grandson of the French servant who wrote his diary in an odd volume of Montesquieu's works. And that is how the diary came into Isilda's hands."
He turned the pages at random:
"15 September, 1796. His Royal Highness went hunting.
"20 September, 1796. His Royal Highness went out riding. He was mounted on Cupidon."
"By Jove!" muttered Lupin. "So far, it's not very exciting."
He turned over a number of pages and read:
"12 March, 1803. I have remitted ten crowns to Hermann. He is giving music-lessons in London."
Lupin gave a laugh:
"Oho! Hermann is dethroned and our respect comes down with a rush!"
"Yes," observed Waldemar, "the reigning grand-duke was driven from his dominions by the French troops."
Lupin continued:
"1809. Tuesday. Napoleon slept at Veldenz last night. I made His Majesty's bed and this morning I emptied his slops."
"Oh, did Napoleon stop at Veldenz?"
"Yes, yes, on his way back to the army, at the time of the Austrian campaign, which ended with the battle of Wagram. It was an honor of which the grand-duchal family were very proud afterwards."
Lupin went on reading:
"28 October, 1814. His Royal Highness returned to his dominions.
"29 October, 1814. I accompanied His Royal Highness to the hiding-place last night and was happy to be able to show him that no one had guessed its existence. For that matter, who would have suspected that a hiding-place could be contrived in...."
Lupin stopped, with a shout. Isilda had suddenly escaped from the men guarding her, made a grab at him and taken to flight, carrying the book with her.
"Oh, the little mischief! Quick, you!.... Go round by the stairs below. I'll run after her by the passage."
But she had slammed the door behind her and bolted it. He had to go down and run along the buildings with the others, looking for a staircase which would take them to the first floor.
The fourth house was the only one open. He went upstairs. But the passage was empty and he had to knock at doors, force locks and make his way into unoccupied rooms, while Waldemar, showing as much ardor in the pursuit as himself, pricked the curtains and hangings with the point of his sword.
A voice called out from the ground-floor, towards the right wing. They rushed in that direction. It was one of the officers' wives, who beckoned to them at the end of a passage and told them that the girl must be in her lodging.
"How do you know?" asked Lupin.
"I wanted to go to my room. The door was shut and I could not get in."
Lupin tried and found the door locked:
"The window!" he cried. "There must be a window!"
He went outside, took the count's sword and smashed the panes. Then, helped up by two men, he hung on to the wall, passed his arm through the broken glass, turned the latch and stumbled into the room.
He saw Isilda huddled before the fireplace, almost in the midst of the flames:
"The little beast!" he said. "She has thrown it into the fire!"
He pushed her back savagely, tried to take the book and burnt his hands in the attempt. Then, with the tongs, he pulled it out of the grate and threw the table cloth over it to stifle the blaze.
But it was too late. The pages of the old manuscript, all burnt up, were falling into ashes.
Lupin gazed at her in silence. The count said:
"One would think that she knew what she was doing."
"No, she does not know. Only, her grandfather must have entrusted her with that book as a sort of treasure, a treasure which no one was ever to set eyes on, and, with her stupid instinct, she preferred to throw it into the fire rather than part with it."
"Well then...."
"Well then what?"
"You won't find the hiding-place."
"Aha, my dear count, so you did, for a moment, look upon my success as possible? And Lupin does not strike you as quite a charlatan? Make your mind easy, Waldemar: Lupin has more than one string to his bow. I shall succeed."
"Before twelve o'clock to-morrow?"
"Before twelve o'clock to-night. But, for the moment, I am starving with hunger. And, if your kindness would go so far...."
He was taken to the sergeants' mess and a substantial meal prepared for him, while the count went to make his report to the Emperor.
TWENTY MINUTES later, Waldemar returned and they sat down and dined together, opposite each other, silent and pensive.
"Waldemar, a good cigar would be a treat.... I thank you.... Ah, this one crackles as a self-respecting Havana should!"
He lit his cigar and, after a minute or two:
"You can smoke, count; I don't mind in the least; in fact, I rather like it."
An hour passed. Waldemar dozed and, from time to time, swallowed a glass of brandy to wake himself up.
Soldiers passed in and out, waiting on them.
"Coffee," asked Lupin.
They brought him some coffee.
"What bad stuff!" he grumbled. "If that's what Cæsar drinks!.... Give me another cup all the same, Waldemar. We may have a long night before us. Oh, what vile coffee!"
He lit a second cigar and did not say another word. Ten minutes passed. He continued not to move or speak.
Suddenly, Waldemar sprang to his feet and said to Lupin, angrily:
"Hi! Stand up, there!"
Lupin was whistling a tune at the moment. He kept on whistling, peacefully.
"Stand up, I say!"
Lupin turned round. His Imperial Majesty had just entered. Lupin rose from his chair.
"How far are we?" asked the Emperor.
"I think, Sire, that I shall be able to satisfy Your Imperial Majesty soon."
"What? Do you know...."
"The hiding-place? Very nearly, Sire.... A few details still escape me.... but everything will be cleared up, once we are on the spot: I have no doubt of it."
"Are we to stay here?"
"No, Sire, I will beg you to go with me to the Renascence palace. But we have plenty of time; and, if Your Imperial Majesty will permit me, I should like first to think over two or three points."
Without waiting for the reply, he sat down, to Waldemar's great indignation.
In a few minutes, the Emperor, who had walked away and was talking to the count, came up to him:
"Are you ready now, M. Lupin?"
Lupin kept silence. A fresh question. His head fell on his chest.
"But he's asleep; I really believe that he's asleep!"
Waldemar, beside himself with rage, shook him violently by the shoulder. Lupin fell from his chair, sank to the floor, gave two or three convulsive movements and then lay quite still.
"What's the matter with him?" exclaimed the Emperor. "He's not dead, I hope!"
He took a lamp and bent over him:
"How pale he is! A face like wax!.... Look, Waldemar.... Feel his heart.... He's alive, is he not?"
"Yes, Sire," said the count, after a moment, "the heart is beating quite regularly."
"Then what is it? I don't understand.... What happened?"
"Shall I go and fetch the doctor?"
"Yes, run...."
The doctor found Lupin in the same state, lying inert and quiet. He had him put on a bed, subjected him to a long examination and asked what he had had to eat.
"Do you suspect a case of poisoning, doctor?"
"No, Sire, there are no traces of poisoning. But I am thinking.... what's on that tray and in that cup?"
"Coffee," said the count.
"For you?"
"No, for him. I did not have any."
The doctor poured out some coffee, tasted it and said:
"I was right. He has been put to sleep with a narcotic."
"But by whom?" cried the Emperor, angrily. "Look here, Waldemar; it's exasperating, the way things happen in this place!"
"Sire?...."
"Well, yes, I've had enough of it!.... I am really beginning to believe that the man's right and that there is some one in the castle.... That French money, that narcotic...."
"If any one had got into this enclosure, Sire, it would be known by this time.... We've been hunting in every direction for three hours."
"Still, I didn't make the coffee, I assure you.... And, unless you did...."
"Oh, Sire!"
"Well, then, hunt about.... search.... You have two hundred men at your disposal; and the out-houses are not so large as all that! For, after all, the ruffian is prowling round here, round these buildings.... near the kitchen.... somewhere or other! Go and bustle about!"
The fat Waldemar bustled about all night, conscientiously, because it was the master's order, but without conviction, because it was impossible for a stranger to hide among ruins which were so well-watched. And, as a matter of fact, the event proved that he was right: the investigations were fruitless; and no one was able to discover the mysterious hand that had prepared the narcotic drink.
Lupin spent the night lifeless on his bed. In the morning, the doctor, who had not left his side, told a messenger of the Emperor's that he was still asleep.
At nine o'clock, however, he made his first movement, a sort of effort to wake up.
Later on, he stammered:
"What time is it?"
"Twenty-five to ten."
He made a fresh effort; and it was evident that, in the midst of his torpor, his whole being was intent upon returning to life.
