“I own that, not having studied ghosts as you have, I am unable to give you a definitive answer.”

“You see! Ghosts show themselves, my dear fellow, in order to frighten those who see them.”

“That is undeniable.”

“Of course! Now, if they don’t frighten those to whom they appear, they are frightened by them; witness M. de Turenne, whose ghosts proved to be counterfeiters. Do you know that story?”

“No.”

“I’ll tell it to you some day; don’t let’s get mixed up. That is just why, when they decide to appear—which is seldom—ghosts select stormy nights, when it thunders, lightens and blows; that’s their scenery.”

“I am forced to admit that nothing could be more correct.”

“Wait a moment! There are instances when the bravest man feels a shudder run through his veins. Even before I was suffering with this aneurism it has happened to me a dozen times, when I have seen the flash of sabres and heard the thunder of cannon around me. It is true that since I have been subject to this aneurism I rush where the lightning flashes and the thunder growls. Still there is the chance that these ghosts don’t know this and believe that I can be frightened.”

“Whereas that is an impossibility, isn’t it?” asked Sir John.

“What will you! When, right or wrong, one feels that, far from dreading death, one has every reason to seek it, what should he fear? But I repeat, these ghosts, who know so much, may not know that only ghosts know this; they know that the sense of fear increases or diminishes according to the seeing and hearing of exterior things. Thus, for example, where do phantoms prefer to appear? In dark places, cemeteries, old cloisters, ruins, subterranean passages, because the aspect of these localities predisposes the soul to fear. What precedes their appearance? The rattling of chains, groans, sighs, because there is nothing very cheerful in all that? They are careful not to appear in the bright light, or after a strain of dance music. No, fear is an abyss into which you descend step by step, until you are overcome by vertigo; your feet slip, and you plunge with closed eyes to the bottom of the precipice. Now, if you read the accounts of all these apparitions, you’ll find they all proceed like this: First the sky darkens, the thunder growls, the wind howls, doors and windows rattle, the lamp—if there is a lamp in the room of the person the ghosts are trying to frighten—the lamp flares, flickers and goes out—utter darkness! Then, in the darkness, groans, wails and the rattling of chains are heard; then, at last, the door opens and the ghost appears. I must say that all the apparitions that I have not seen but read about have presented themselves under similar circumstances. Isn’t that so, Sir John?”
