The evidence of the night-nurse bears with terrible weight upon this point. Her orders are strict, on no account to close her eyes. Her hours of watch are short, and the repose of the entire day leaves her without the slightest cause for unusual drowsiness. The testimonials of twenty years bear unvarying witness to her care and trustworthiness. Yet every alternate Saturday for eight or ten, or it may even have been nearly twelve weeks, at one regular hour she falls asleep. It is in vain that she watches and fights against it--in vain even that, suspecting "some trick" she on one occasion abstains entirely from food, and drinks nothing but that peculiarly wakeful decoction, strong green tea. On every other night she keeps awake with ease, but surely as the fatal Saturday comes round she again succumbs, and surely as sleep steals over her is it followed by a fresh attack of the symptoms we so plainly recognise. She cannot in any way account for such an extraordinary fatality. She is positive that such a thing never happened to her before. We also are at an equal loss. We can but pause upon the reflection that twice before the periodic drowsiness began, a similarly irresistible sleep had been induced by the so-called mesmeric powers of the Baron himself. And then we pass naturally to her who had been for years habituated to such control, and we cannot but call to mind the statement of Mr. Hands--"I have often _willed_ her (S. Parsons) to go into a dark room and pick up a pin, or some article equally minute." _And then we again remember the watching shadow on the wall._ And yet, after all, at what have we arrived? Grant that the Baron knew the nature of his wife's errand in the laboratory; that the singular power--call it what we will--by which he had before in jest compelled the nurse to sleep, was really employed in enabling the somnambulist to elude her watch. Grant even that the pretensions of the mesmerist are true, and that it was in obedience to his direct will that Madame R** acted as she did, we are no nearer a solution than before. _It was not the Baron's interest that his wife should die._ We must then seek further afield for any explanation of this terrible enigma. Let us see how it fared with Mrs. Anderton while these events were passing at her sister's house.
