Monsieur Stangerson intervened:
"What you say was impossible. I do not believe either in the guilt or in the connivance of my concierges, though I cannot understand what they were doing in the park at that late hour of the night. I say it was impossible, because Madame Bernier held the lamp and did not move from the threshold of the room; because I, as soon as the door was forced open, threw myself on my knees beside my daughter, and no one could have left or entered the room by the door, without passing over her body and forcing his way by me! Daddy Jacques and the concierge had but to cast a glance round the chamber and under the bed, as I had done on entering, to see that there was nobody in it but my daughter lying on the floor."
"What do you think, Monsieur Darzac?" asked the magistrate.
Monsieur Darzac replied that he had no opinion to express. Monsieur Dax, the Chief of the Surete who, so far, had been listening and examining the room, at length deigned to open his lips:
"While search is being made for the criminal, we had better try to find out the motive for the crime; that will advance us a little," he said. Turning towards Monsieur Stangerson, he continued, in the even, intelligent tone indicative of a strong character, "I understand that Mademoiselle was shortly to have been married?"
The professor looked sadly at Monsieur Robert Darzac.
"To my friend here, whom I should have been happy to call my son—to Monsieur Robert Darzac."
"Mademoiselle Stangerson is much better and is rapidly recovering from her wounds. The marriage is simply delayed, is it not, Monsieur?" insisted the Chief of the Surete.
"I hope so.
"What! Is there any doubt about that?"
Monsieur Stangerson did not answer. Monsieur Robert Darzac seemed agitated. I saw that his hand trembled as it fingered his watchchain. Monsieur Dax coughed, as did Monsieur de Marquet. Both were evidently embarrassed.
"You understand, Monsieur Stangerson," he said, "that in an affair so perplexing as this, we cannot neglect anything; we must know all, even the smallest and seemingly most futile thing concerning the victim—information apparently the most insignificant. Why do you doubt that this marriage will take place? You expressed a hope; but the hope implies a doubt. Why do you doubt?"
Monsieur Stangerson made a visible effort to recover himself.
"Yes, Monsieur," he said at length, "you are right. It will be best that you should know something which, if I concealed it, might appear to be of importance; Monsieur Darzac agrees with me in this."
Monsieur Darzac, whose pallor at that moment seemed to me to be altogether abnormal, made a sign of assent. I gathered he was unable to speak.
"I want you to know then," continued Monsieur Stangerson, "that my daughter has sworn never to leave me, and adheres firmly to her oath, in spite of all my prayers and all that I have argued to induce her to marry. We have known Monsieur Robert Darzac many years. He loves my child; and I believed that she loved him; because she only recently consented to this marriage which I desire with all my heart. I am an old man, Monsieur, and it was a happy hour to me when I knew that, after I had gone, she would have at her side, one who loved her and who would help her in continuing our common labours. I love and esteem Monsieur Darzac both for his greatness of heart and for his devotion to science. But, two days before the tragedy, for I know not what reason, my daughter declared to me that she would never marry Monsieur Darzac."
A dead silence followed Monsieur Stangerson's words. It was a moment fraught with suspense.
"Did Mademoiselle give you any explanation,—did she tell you what her motive was?" asked Monsieur Dax.
"She told me she was too old to marry—that she had waited too long. She said she had given much thought to the matter and while she had a great esteem, even affection, for Monsieur Darzac, she felt it would be better if things remained as they were. She would be happy, she said, to see the relations between ourselves and Monsieur Darzac become closer, but only on the understanding that there would be no more talk of marriage."
"That is very strange!" muttered Monsieur Dax.
"Strange!" repeated Monsieur de Marquet.
"You'll certainly not find the motive there, Monsieur Dax," Monsieur Stangerson said with a cold smile.
"In any case, the motive was not theft!" said the Chief impatiently.
"Oh! we are quite convinced of that!" cried the examining magistrate.
At that moment the door of the laboratory opened and the officer in charge of the gendarmes entered and handed a card to the examining magistrate. Monsieur de Marquet read it and uttered a half angry exclamation:
"This is really too much!" he cried.
"What is it?" asked the Chief.
"It's the card of a young reporter engaged on the 'Epoque,' a Monsieur Joseph Rouletabille. It has these words written on it: 'One of the motives of the crime was robbery.'"
The Chief smiled.
"Ah,—young Rouletabille—I've heard of him he is considered rather clever. Let him come in."
Monsieur Joseph Rouletabille was allowed to enter. I had made his acquaintance in the train that morning on the way to Epinay–sur–Orge. He had introduced himself almost against my wish into our compartment. I had better say at once that his manners, and the arrogance with which he assumed to know what was incomprehensible even to us, impressed him unfavourably on my mind. I do not like journalists. They are a class of writers to be avoided as the pest. They think that everything is permissible and they respect nothing. Grant them the least favour, allow them even to approach you, and you never can tell what annoyance they may give you. This one appears to be scarcely twenty years old, and the effrontery with which he dared to question us and discuss the matter with us made him particularly obnoxious to me. Besides, he had a way of expressing himself that left us guessing as to whether he was mocking us or not. I know quite well that the 'Epoque' is an influential paper with which it is well to be on good terms, but the paper ought not to allow itself to be represented by sneaking reporters.
Monsieur Joseph Rouletabille entered the laboratory, bowed to us, and waited for Monsieur de Marquet to ask him to explain his presence.
"You pretend, Monsieur, that you know the motive for the crime, and that that motive—in the face of all the evidence that has been forthcoming—was robbery?"
"No, Monsieur, I do not pretend that. I do not say that robbery was the motive for the crime, and I don't believe it was."
"Then, what is the meaning of this card?"
"It means that robbery was one of the motives for the crime."
"What leads you to think that?"
"If you will be good enough to accompany me, I will show you."
The young man asked us to follow him into the vestibule, and we did. He led us towards the lavatory and begged Monsieur de Marquet to kneel beside him. This lavatory is lit by the glass door, and, when the door was open, the light which penetrated was sufficient to light it perfectly. Monsieur de Marquet and Monsieur Joseph Rouletabille knelt down on the threshold, and the young man pointed to a spot on the pavement.
"The stones of the lavatory have not been washed by Daddy Jacques for some time," he said; "that can be seen by the layer of dust that covers them. Now, notice here, the marks of two large footprints and the black ash they left where they have been. That ash is nothing else than the charcoal dust that covers the path along which you must pass through the forest, in order to get directly from Epinay to the Glandier. You know there is a little village of charcoal–burners at that place, who make large quantities of charcoal. What the murderer did was to come here at midday, when there was nobody at the pavilion, and attempt his robbery."
