“Could he ever remember?”

“There is only one way in which he could.”

“How is that?”

“If he could return to the same scenes and conditions through which he passed during those three months.”

“But for that you would have to know, of course, what those scenes and conditions were?”

“Exactly, Senorita.”

“Really, it is all very interesting,” she said dreamily. “I have heard something like it in fairy tales, I think; but not in real life. And now—why do you tell all this to me, Senor?” she asked, as if struck by a novel idea.

“Ah, Sajipona,” he replied with a smile; “I have told you merely in answer to your own questions. You have shown that—for some reason or other—you are interested.”

“Interested? Why, of course I am interested—if for no other reason, simply because you are. This David Meudon, you say, left Bogota three years ago? Strange that he should leave so suddenly—and with his work in this country unfinished!”

“I can’t tell how much you know of David,” he said musingly. “But there is every reason why you, more than anyone else, should be interested in the man who attempts to solve the secret of Guatavita—Sajipona.”
