When the trial was resumed, Maître Henri Robert questioned Daddy Mathieu as to his complicity in the death of the keeper. His wife was also brought in and was confronted by her husband. She burst into tears and confessed that she had been the keeper’s mistress, and that her husband had suspected it. She again, however, affirmed that he had had nothing to do with the murder of her lover. Maître Henri Robert thereupon asked the court to hear Frédéric Larsan on this point.

“In a short conversation which I have had with Frédéric Larsan, during the adjournment,” declared the advocate, “he has made me understand that the death of the keeper may have been brought about otherwise than by the hand of Mathieu. It will be interesting to hear Frédéric Larsan’s theory.”

Frédéric Larsan was brought in. His explanation was quite clear.

“I see no necessity,” he said, “for bringing Mathieu in this. I have told Monsieur de Marquet that the man’s threats had biassed the examining magistrate against him. To me the attempt to murder Mademoiselle and the death of the keeper are the work of one and the same person. Mademoiselle Stangerson’s murderer, flying through the court, was fired on; it was thought he was struck, perhaps killed. As a matter of fact, he only stumbled at the moment of his disappearance behind the corner of the right wing of the château. There he encountered the keeper who, no doubt, tried to seize him. The murderer had in his hand the knife with which he had stabbed Mademoiselle Stangerson and with this he killed the keeper.”

This very simple explanation appeared at once plausible and satisfying. A murmur of approbation was heard.

“And the murderer? What became of him?” asked the President.

“He was evidently hidden in an obscure corner at the end of the court. After the people had left the court carrying with them the body of the keeper, the murderer quietly made his escape.”

The words had scarcely left Larsan’s mouth when from the back of the court came a youthful voice:—

“I agree with Frédéric Larsan as to the death of the keeper; but I do not agree with him as to the way the murderer escaped!”

Everybody turned round, astonished. The clerks of the court sprang towards the speaker, calling out silence, and the President angrily ordered the intruder to be immediately expelled. The same clear voice, however, was again heard:—
