"Nevertheless," Rénine objected, "it is not to drive away that picture that she commits murder?"

"Yes, possibly," said M. de Lourtier, thoughtfully, "to drive it away by sleep."

"I don't understand."

"You don't understand, because we are talking of a madwoman ... and because all that happens in that disordered brain is necessarily incoherent and abnormal?"

"Obviously. But, all the same, is your supposition based on facts that justify it?"

"Yes, on facts which I had, in a way, overlooked but which to-day assume their true significance. The first of these facts dates a few years back, to a morning when my old nurse for the first time found Hermance fast asleep. Now she was holding her hands clutched around a puppy which she had strangled. And the same thing was repeated on three other occasions."

"And she slept?"

"Yes, each time she slept a sleep which lasted for several nights."

"And what conclusion did you draw?"

"I concluded that the relaxation of the nerves provoked by taking life exhausted her and predisposed her for sleep."
