pile up a crushing indictment against the young man. "The crime was committed so quietly that not the faintest sound was heard; therefore the murderer was in the house; he went to the Marquise's room and announced his arrival by a cautious tap on the door; the Marquise then opened the door to him, and was not surprised to see him, for she knew him quite well; he went into her room with her and —— "
"Oh, come, come!" M. de Presles broke in; "you are romancing now, M. Juve; you forget that the bedroom door was forced, the best proof of that being the bolt, which was found wrenched away and hanging literally at the end of the screws."
"I was expecting you to say that, sir," said Juve with a smile. "But before I reply I should like to show you something rather quaint." He led the way across the passage and went into the bedroom of the Marquise, where order had now been restored; the dead body had been removed to the library, which was transformed into a chapelle ardente, and two nuns were watching over it there. "Have a good look at this bolt," he said to M. de Presles. "Is there anything unusual about it?"
"No," said the magistrate.
"Yes, there is," said Juve; "the slide-bolt is out, as when the bolt is fastened, but the socket into which the slide-bolt slips to fasten the door to the wall is intact. If the bolt really had been forced, the socket would have been wrenched away too." Juve next asked M. de Presles to look closely at the screws that were wrenched halfway out of the door. "Do you see anything on those?"
The magistrate pointed to their heads.
"There are tiny scratches on them," he said, rather hesitatingly, for in his inmost heart he knew the detective's real superiority over himself, "and from those I must infer that the screws have not been wrenched out by the pressure exerted on the bolt, but really unscrewed, and therefore —— "
"And therefore," Juve broke in, "this is a mere blind, from which we may certainly draw the conclusion that the murderer wished to make us believe that the door was forced, whereas in reality it was opened to him by the Marquise. Therefore the murderer was personally known to her!"
"The murderer was personally known to her," he repeated. "Now I should like to remind you of young Charles Rambert's equivocal behaviour in the course of the evening that preceded the crime. It struck President Bonnet and shocked the priest. I also recall his hereditary antecedents, his mothers insanity, and finally —— " Juve broke off abruptly and unceremoniously dragged the magistrate out of the room and into Charles Rambert's bedroom. He hurried into the dressing-room adjoining, went down on his knees on the floor, and laid a finger on the middle of the oil-cloth that was laid over the boards. "What do you see there, sir?" he demanded.
The magistrate adjusted his eyeglass and, looking at the place indicated by the detective, saw a little black stain; he wetted his finger, rubbed it on the spot, and then, holding up his hand, observed that the tip of his finger was stained red.
"It is blood," he muttered.
"Yes, blood," said Juve, "and I gather from this that the story of the blood-stained towel which M. Rambert senior found among his son's things, and the sight of which so greatly impressed Mlle. Thérèse, was not an invention on that young lady's part, but really existed; and it forms the most damning evidence possible against the young man. He obviously washed his hands after the crime in the water from the tap over this wash-hand basin here, but one drop of blood falling on the towel and dripping on to the floor has been enough to give him away."
The magistrate nodded.
"It is conclusive," he said. "You have just proved to demonstration, M. Juve, that Charles Rambert is the guilty party. It is beyond argument. It is conclusive — conclusive!"
There were a couple of seconds of silence, and then Juve suddenly said "No!"
"No!" he repeated; "it is quite true that we can adduce perfectly logical arguments to show that the murder was committed by some member of the household and that, therefore, Charles Rambert is the only possible culprit; but we can adduce equally logical arguments to show that the crime was committed by some person who got in from outside: there is nothing to prove that he did not walk into the house through the front door."
"The door was locked," said the magistrate.
"That's nothing," said Juve with a laugh. "Don't forget that there isn't such a thing as a real safety lock nowadays — since all locks can be opened with an outside key. If I had found one of the good old-fashioned catch locks on the door, such as they used to make years ago, I should have said to you: nobody got in, because the only way to get through a door fastened with one of those locks is to break the door down. But here we have a lock that can be opened with a key. Now the key does not exist of which one cannot get an impression, and there is not such a thing as an impression from which one cannot manufacture a false key. The murderer could easily have got into the house with a duplicate key."
The magistrate raised a further objection.
"If the murderer had got in from outside he would inevitably have left some traces round about the château, but there aren't any."
"Yes there are," Juve retorted. "First of all there is this piece of an ordnance map which I found yesterday between the château and the embankment." He took it from his pocket as he spoke. "It is an odd coincidence that this scrap shows the neighbourhood of the château of Beaulieu."
"That doesn't prove anything," said the magistrate. "To find a piece of a map of our district in our district is the most natural thing possible. Now if you were to discover the rest of this map in anybody's possession, then —— "
"You may rest assured that I shall try to do so with the least possible delay," said Juve gently. "But this is not the only argument I have to support my theory. This morning, when I was walking near the embankment, I found some very suspicious footprints. It is true there are any number of footprints near the end of the Verrières tunnel, where the navvies are at work. But at the other end of the tunnel, where there is no occasion for anyone to pass by, I found that the earth of the embankment, which was crisp with the frost, had been disturbed, showing that someone had clambered up the embankment; the tips of his shoes had been driven into the earth, and I could see distinctly where his feet had been placed; but unfortunately the soil there is so dry that the footprints were too faint for me to hope to be able to identify the maker of them. But the fact remains that someone did climb up the embankment, someone who was making for the railway."
The magistrate did not seem to be impressed by Juve's discovery.
"And pray what conclusion do you think ought to be drawn from that?" he enquired.
Juve sat down in an easy chair, threw back his head and closed his eyes as if he were about to indulge in a long soliloquy, and began to express his thoughts aloud.
"Suppose we were to combine the two hypotheses into one; to wit, that the murderer was in the château prior to the accomplishment of the crime and left the château directly it was accomplished. What should you say, sir, of a criminal completing his deed, then hurrying over the couple of miles that separate Beaulieu from the railway, and catching a passing train, and on his way climbing the embankment at the spot where I found the footprints I mentioned."
"I should say," the magistrate replied, "that you can't jump into a moving train as you can into a passing tram, and further, that at night none but express trains run between Brives and Cahors."
"All right," said Juve: "I will merely point out that owing to the work on the line at present, all trains have stopped at the beginning of the tunnel for the last two months. If the murderer had planned to escape in that way he might very well
