reporter; and this evening I shall have to give a little account
   of the play at the Scala."
   "Get in, sir, please," said the Registrar.
   Rouletabille was already in the compartment.  I went in after him
   and seated myself by his side.  The Registrar followed and closed
   the carriage door.
   Monsieur de Marquet looked at him.
   "Ah, sir," Rouletabille began, "You must not be angry with Monsieur
   de Maleine.  It is not with Monsieur de Marquet that I desire to
   have the honour of speaking, but with Monsieur 'Castigat Ridendo.'
   Permit me to congratulate you--personally, as well as the writer
   for the 'Epoque.'"  And Rouletabille, having first introduced me,
   introduced himself.
   Monsieur de Marquet, with a nervous gesture, caressed his beard into
   a point, and explained to Rouletabille, in a few words, that he was
   too modest an author to desire that the veil of his pseudonym should
   be publicly raised, and that he hoped the enthusiasm of the
   journalist for the dramatist's work would not lead him to tell the
   public that Monsieur "Castigat Ridendo" and the examining magistrate
   of Corbeil were one and the same person.
   "The work of the dramatic author may interfere," he said, after a
   slight hesitation, "with that of the magistrate, especially in a
   province where one's labours are little more than routine."
   "Oh, you may rely on my discretion!" cried Rouletabille.
   The train was in motion.
   "We have started!" said the examining magistrate, surprised at
   seeing us still in the carriage.
   "Yes, Monsieur,--truth has started," said Rouletabile, smiling
   amiably,--"on its way to the Chateau du Glandier.  A fine case,
   Monsieur de Marquet,--a fine case!"
   "An obscure--incredible, unfathomable, inexplicable affair--and
   there is only one thing I fear, Monsieur Rouletabille,--that the
   journalists will be trying to explain it."
   My friend felt this a rap on his knuckles.
   "Yes," he said simply, "that is to be feared.  They meddle in
   everything.  As for my interest, monsieur, I only referred to it by
   mere chance,--the mere chance of finding myself in the same train
   with you, and in the same compartment of the same carriage."
   "Where are you going, then?" asked Monsieur de Marquet.
   "To the Chateau du Glandier," replied Rouletabille, without turning.
   "You'll not get in, Monsieur Rouletabille!"
   "Will you prevent me?" said my friend, already prepared to fight.
   "Not I!--I like the press and journalists too well to be in any
   way disagreeable to them; but Monsieur Stangerson has given orders
   for his door to be closed against everybody, and it is well guarded.
   Not a journalist was able to pass through the gate of the Glandier
   yesterday."
   Monsieur de Marquet compressed his lips and seemed ready to relapse
   into obstinate silence.  He only relaxed a little when Rouletabille
   no longer left him in ignorance of the fact that we were going to
   the Glandier for the purpose of shaking hands with an "old and
   intimate friend," Monsieur Robert Darzac--a man whom Rouletabille
   had perhaps seen once in his life.
   "Poor Robert!" continued the young reporter, "this dreadful affair
   may be his death,--he is so deeply in love with Mademoiselle
   Stangerson."
   "His sufferings are truly painful to witness," escaped like a regret
   from the lips of Monsieur de Marquet.
   "But it is to be hoped that Mademoiselle Stangerson's life will be
   saved."
   "Let us hope so.  Her father told me yesterday that, if she does not
   recover, it will not be long before he joins her in the grave.  What
   an incalculable loss to science his death would be!"
   "The wound on her temple is serious, is it not?"
   "Evidently; but, by a wonderful chance, it has not proved mortal.
   The blow was given with great force."
   "Then it was not with the revolver she was wounded," said
   Rouletabille, glancing at me in triumph.
   Monsieur de Marquet appeared greatly embarrassed.
   "I didn't say anything--I don't want to say anything--I will not
   say anything," he said.  And he turned towards his Registrar as if
   he no longer knew us.
   But Rouletabille was not to be so easily shaken off.  He moved
   nearer to the examining magistrate and, drawing a copy of the
   "Matin" from his pocket, he showed it to him and said:
   "There is one thing, Monsieur, which I may enquire of you without
   committing an indiscretion.  You have, of course, seen the account
   given in the 'Matin'?  It is absurd, is it not?"
   "Not in the slightest, Monsieur."
   "What!  The Yellow Room has but one barred window--the bars of
   which have not been moved--and only one door, which had to be
   broken open--and the assassin was not found!"
   "That's so, monsieur,--that's so.  That's how the matter stands."
   Rouletabille said no more but plunged into thought.  A quarter of
   an hour thus passed.
   Coming back to himself again he said, addressing the magistrate:
   "How did Mademoiselle Stangerson wear her hair on that evening?"
   "I don't know," replied Monsieur de Marquet.
   "That's a very important point," said Rouletabille.  "Her hair was
   done up in bands, wasn't it?  I feel sure that on that evening, the
   evening of the crime, she had her hair arranged in bands."
   "Then you are mistaken, Monsieur Rouletabille," replied the
   magistrate; "Mademoiselle Stangerson that evening had her hair drawn
   up in a knot on the top of her head,--her usual way of arranging it
   --her forehead completely uncovered.  I can assure you, for we have
   carefully examined the wound.  There was no blood on the hair, and
   the arrangement of it has not been disturbed since the crime was
   committed."
   "You are sure!  You are sure that, on the night of the crime, she
   had not her hair in bands?"
   "Quite sure," the magistrate continued, smiling, "because I
   remember the Doctor saying to me, while he was examining the wound,
   'It is a great pity Mademoiselle Stangerson was in the habit of
   drawing her hair back from her forehead.  If she had worn it in
   bands, the blow she received on the temple would have been weakened.'
   It seems strange to me that you should attach so much importance
   to this point."
   "Oh!  if she had not her hair in bands, I give it up," said
   Rouletabille, with a despairing gesture.
   "And was the wound on her temple a bad one?" he asked presently.
   "Terrible."
   "With what weapon was it made?"
   "That is a secret of the investigation."
   "Have you found the weapon--whatever it was?"
   The magistrate did not answer.
    "And the wound in the throat?"
   Here the examining magistrate readily confirmed the decision of the
   doctor that, if the murderer had pressed her throat a few seconds
   longer, Mademoiselle Stangerson would have died of strangulation.
   "The affair as reported in the 'Matin,'" said Rouletabille eagerly,
   "seems to me more and more inexplicable.  Can you tell me, Monsieur,
   how many openings there are in the p 
					     					 			avilion?  I mean doors and
   windows."
   "There are five," replied Monsieur de Marquet, after having coughed
   once or twice, but no longer resisting the desire he felt to talk
   of the whole of the incredible mystery of the affair he was
   investigating.  "There are five, of which the door of the vestibule
   is the only entrance to the pavilion,--a door always automatically
   closed, which cannot be opened, either from the outer or inside,
   except with the two special keys which are never out of the
   possession of either Daddy Jacques or Monsieur Stangerson.
   Mademoiselle Stangerson had no need for one, since Daddy Jacques
   lodged in the pavilion and because, during the daytime, she never
   left her father.  When they, all four, rushed into The Yellow Room,
   after breaking open the door of the laboratory, the door in the
   vestibule remained closed as usual and, of the two keys for opening
   it, Daddy Jacques had one in his pocket, and Monsieur Stangerson
   the other.  As to the windows of the pavilion, there are four; the
   one window of The Yellow Room and those of the laboratory looking
   out on to the country; the window in the vestibule looking into
   the park."
   "It is by that window that he escaped from the pavilion!" cried
   Rouletabille.
   "How do you know that?" demanded Monsieur de Marquet, fixing a
   strange look on my young friend.
   "We'll see later how he got away from The Yellow Room," replied
   Rouletabille, "but he must have left the pavilion by the vestibule
   window."
   "Once more,--how do you know that?"
   "How?  Oh, the thing is simple enough!  As soon as he found he could
   not escape by the door of the pavilion his only way out was by the
   window in the vestibule, unless he could pass through a grated window.
   The window of The Yellow Room is secured by iron bars, because it
   looks out upon the open country; the two windows of the laboratory
   have to be protected in like manner for the same reason.  As the
   murderer got away, I conceive that he found a window that was not
   barred,--that of the vestibule, which opens on to the park,--that
   is to say, into the interior of the estate.  There's not much magic
   in all that."
   "Yes," said Monsieur de Marquet, "but what you have not guessed is
   that this single window in the vestibule, though it has no iron bars,
   has solid iron blinds.  Now these iron blinds have remained fastened
   by their iron latch; and yet we have proof that the murderer made
   his escape from the, pavilion by that window!  Traces of blood on
   the inside wall and on the blinds as well as on the floor, and
   footmarks, of which I have taken the measurements, attest the fact
   that the murderer made his escape that way.  But then, how did he
   do it, seeing that the blinds remained fastened on the inside?  He
   passed through them like a shadow.  But what is more bewildering
   than all is that it is impossible to form any idea as to how the
   murderer got out of The Yellow Room, or how he got across the
   laboratory to reach the vestibule!  Ah, yes, Monsieur Rouletabille,
   it is altogether as you said, a fine case, the key to which will
   not be discovered for a long time, I hope."
   "You hope, Monsieur?"
   Monsieur de Marquet corrected himself.
   "I do not hope so,--I think so."
   "Could that window have been closed and refastened after the flight
   of the assassin?" asked Rouletabille.
   "That is what occurred to me for a moment; but it would imply an
   accomplice or accomplices,--and I don't see--"
   After a short silence he added:
   "Ah--if Mademoiselle Stangerson were only well enough to-day to
   be questioned!"
   Rouletabille following up his thought, asked:
   "And the attic?--There must be some opening to that?"
   "Yes; there is a window, or rather skylight, in it, which, as it
   looks out towards the country, Monsieur Stangerson has had barred,
   like the rest of the windows.  These bars, as in the other windows,
   have remained intact, and the blinds, which naturally open inwards,
   have not been unfastened.  For the rest, we have not discovered
   anything to lead us to suspect that the murderer had passed through
   the attic."
   "It seems clear to you, then, Monsieur, that the murderer escaped
   --nobody knows how--by the window in the vestibule?"
   "Everything goes to prove it."
   "I think so, too," confessed Rouletabille gravely.
   After a brief silence, he continued:
   "If you have not found any traces of the murderer in the attic, such
   as the dirty footmarks similar to those on the floor of The Yellow
   Room, you must come to the conclusion that it was not he who stole
   Daddy Jacques's revolver."
   "There are no footmarks in the attic other than those of Daddy
   Jacques himself," said the magistrate with a significant turn of his
   head.  Then, after an apparent decision, he added: "Daddy Jacques
   was with Monsieur Stangerson in the laboratory--and it was lucky
   for him he was."
   "Then what part did his revolver play in the tragedy?--It seems
   very clear that this weapon did less harm to Mademoiselle Stangerson
   than it did to the murderer."
   The magistrate made no reply to this question, which doubtless
   embarrassed him.  "Monsieur Stangerson," he said, "tells us that the
   two bullets have been found in The Yellow Room, one embedded in the
   wall stained with the impression of a red hand--a man's large hand
   --and the other in the ceiling."
   "Oh!  oh!  in the ceiling!" muttered Rouletabille.  "In the ceiling!
   That's very curious!--In the ceiling!"
   He puffed awhile in silence at his pipe, enveloping himself in the
   smoke.  When we reached Savigny-sur-Orge, I had to tap him on the
   shoulder to arouse him from his dream and come out on to the
   platform of the station.
   There, the magistrate and his Registrar bowed to us, and by rapidly
   getting into a cab that was awaiting them, made us understand that
   they had seen enough of us.
   "How long will it take to walk to the Chateau du Glandier?"
   Rouletabille asked one of the railway porters.
   "An hour and a half or an hour and three quarters--easy walking,"
   the man replied.
   Rouletabille looked up at the sky and, no doubt, finding its
   appearance satisfactory, took my arm and said:
   "Come on!--I need a walk."
   "Are things getting less entangled?" I asked.
   "Not a bit of it!" he said, "more entangled than ever!  It's true,
   I have an idea--"
   "What's that?" I asked.
   "I can't tell you what it is just at present--it's an idea
   involving the life or death of two persons at least."
   "Do you think there were accomplices?"
   "I don't think it--"
   We fell into silence.  Presently he went on:
   "It was a bit of luck, our falling in with that examining magistrate
   and his Registrar, eh?  What did I tell you about that revolver?"
   His head was bent down, he had his hands in his pockets, and he was
   whistling.  After a while I heard him murmur:
 
					     					 			
   "Poor woman!"
   "Is it Mademoiselle Stangerson you are pitying?"
   "Yes; she's a noble woman and worthy of being pitied!--a woman of
   a great, a very great character--I imagine--I imagine."
   "You know her then?"
   "Not at all.  I have never seen her."
   "Why, then, do you say that she is a woman of great character?"
   "Because she bravely faced the murderer; because she courageously
   defended herself--and, above all, because of the bullet in the
   ceiling."
   I looked at Rouletabille and inwardly wondered whether he was not
   mocking me, or whether he had not suddenly gone out of his senses.
   But I saw that he had never been less inclined to laugh, and the
   brightness of his keenly intelligent eyes assured me that he
   retained all his reason.  Then, too, I was used to his broken way
   of talking, which only left me puzzled as to his meaning, till,
   with a very few clear, rapidly uttered words, he would make the
   drift of his ideas clear to me, and I saw that what he had
   previously said, and which had appeared to me void of meaning, was
   so thoroughly logical that I could not understand how it was I had
   not understood him sooner.
   CHAPTER IV
   "In the Bosom of Wild Nature"
   The Chateau du Glandier is one of the oldest chateaux in the Ile de
   France, where so many building remains of the feudal period are
   still standing.  Built originally in the heart of the forest, in the
   reign of Philip le Bel, it now could be seen a few hundred yards
   from the road leading from the village of Sainte-Genevieve to
   Monthery.  A mass of inharmonious structures, it is dominated by a
   donjon.  When the visitor has mounted the crumbling steps of this
   ancient donjon, he reaches a little plateau where, in the seventeenth
   century, Georges Philibert de Sequigny, Lord of the Glandier,
   Maisons-Neuves and other places, built the existing town in an
   abominably rococo style of architecture.
   It was in this place, seemingly belonging entirely to the past, that
   Professor Stangerson and his daughter installed themselves to lay
   the foundations for the science of the future.  Its solitude, in
   the depths of woods, was what, more than all, had pleased them.
   They would have none to witness their labours and intrude on their
   hopes, but the aged stones and grand old oaks.  The Glandier
   --ancient Glandierum--was so called from the quantity of glands
   (acorns) which, in all times, had been gathered in that
   neighbourhood.  This land, of present mournful interest, had fallen
   back, owing to the negligence or abandonment of its owners, into
   the wild character of primitive nature.  The buildings alone, which
   were hidden there, had preserved traces of their strange
   metamorphoses.  Every age had left on them its imprint; a bit of
   architecture with which was bound up the remembrance of some terrible
   event, some bloody adventure.  Such was the chateau in which science
   had taken refuge--a place seemingly designed to be the theatre of
   mysteries, terror, and death.
   Having explained so far, I cannot refrain from making one further
   reflection.  If I have lingered a little over this description of
   the Glandier, it is not because I have reached the right moment for
   creating the necessary atmosphere for the unfolding of the tragedy
   before the eyes of the reader.  Indeed, in all this matter, my
   first care will be to be as simple as is possible.  I have no
   ambition to be an author.  An author is always something of a
   romancer, and God knows, the mystery of The Yellow Room is quite
   full enough of real tragic horror to require no aid from literary
   effects.  I am, and only desire to be, a faithful "reporter." My
