like many other old people; and on the night in question he could not close an eye, therefore, about half past nine the housekeeper struck a light in the kitchen, which she reached by crossing the passage, and sat down at the table beside her master with an old chronicle-book, from which she read aloud, whilst the old man, fixing his thoughts on the reading, sometimes sat in his arm-chair, sometimes walked slowly up and down the room to try and bring on sleepiness. All was silence in the house till nearly midnight; but then they heard overhead rapid footsteps, a heavy fall, as of something on to the floor, and immediately after that a hollow groaning. They both were struck by a peculiar alarm and anxiety, the horror of the terrible deed which had just been committed seemed to sweep past them. When day came what had been done in the darkness was brought clearly to light." "But, in the name of all the Saints," cried Mademoiselle Scuderi, "considering all the circumstances which I have told you at such length, can you think of any _motive_ for this diabolical deed?" "Hm!" answered La Regnie. "Cardillac was anything but a poor man. He had valuable jewels in his possession." "But all he had would go to the daughter! You forget that Olivier was to be Cardillac's son-in-law." "Perhaps he was compelled to share with others," said La Regnie, "or to do the deed wholly for them!" "Share!--murder for others!" cried Mademoiselle Scuderi, in utter amaze. "You must learn, Mademoiselle," continued La Regnie, "that Olivier's blood would have been flowing on the Place de Grève before this time, but that his crime is connected with that deeply-hidden mystery which has so long brooded over Paris. It is clear that Olivier belongs to that formidable band which, setting at defiance every attempt at observation or discovery, carries on its nefarious practices with perfect immunity. Through him everything will, must be discovered. Cardillac's wound is precisely the same as all those of the persons who have been robbed and murdered in the streets and houses; and most conclusive of all, since Olivier's arrest, the robberies and murders have ceased; the streets are as safe by night as by day. Proof enough that Olivier was most probably the chief of the band. As yet he will not confess; but there are means of making him speak against his will." "And Madelon!" cried Mademoiselle Scuderi, "that truthful, innocent creature." "Ah!" cried La Regnie, with one of his venomous smiles, "who answers to me that _she_ is not in the plot, too? She does not care so very much about her father. Her tears are all for the murderer boy." "What?" cried Mademoiselle Scuderi, "not for her father?--that girl--impossible!" "Oh!" continued La Regnie, "remember the Brinvilliers! You must pardon me, if by-and-by I have to carry off your _protégée_, and put her in the Conciergerie."
