"Very true. It does look like a grave."
"Yes," continued my friend, his eyes still fixed on the spot. "But the strange thing is that I see the body lying on the top of it. Of course," continued Holger, turning his head on one side as artists do, "it must be an effect of light. In the first place, it is not a grave at all. Secondly, if it were, the body would be inside and not outside. Therefore, it's an effect of the moonlight. Don't you see it?"
"Perfectly; I always see it on moonlight nights."
"It doesn't seem to interest you much," said Holger.
"On the contrary, it does interest me, though I am used to it. You're not so far wrong, either. The mound is really a grave."
"Nonsense!" cried Holger, incredulously. "I suppose you'll tell me what I see lying on it is really a corpse!"
"No," I answered, "it's not. I know, because I have taken the trouble to go down and see."
"Then what is it?" asked Holger.
"It's nothing."
