Part 51

She thanked him in the same words she might have used to a man in her own social circle, so I concluded that she had not witnessed the final scene between Varin and Arsène Lupin. But the surprising revelation caused me considerable embarrassment. Lupin! My club companion was none other than Arsène Lupin. I could not realize it. But he said, quite at his ease:

“You can say farewell to Jean Daspry.”

“Ah!”

“Yes, Jean Daspry is going on a long journey. I shall send him to Morocco. There, he may find a death worthy of him. I may say that that is his expectation.”

“But Arsène Lupin will remain?”

“Oh! Decidedly. Arsène Lupin is simply at the threshold of his career, and he expects---”

I was impelled by curiosity to interrupt him, and, leading him away from the hearing of Madame Andermatt, I asked:

“Did you discover the smaller safe yourself--the one that held the letters?”

“Yes, after a great deal of trouble. I found it yesterday afternoon while you were asleep. And yet, God knows it was simple enough! But the simplest things are the ones that usually escape our notice.” Then, showing me the seven-of-hearts, he added: “Of course I had guessed that, in order to open the larger safe, this card must be placed on the sword of the mosaic king.”

“How did you guess that?”

“Quite easily. Through private information, I knew that fact when I came here on the evening of 22 June---”

“After you left me---”

“Yes, after turning the subject of our conversation to stories of crime and robbery which were sure to reduce you to such a nervous condition that you would not leave your bed, but would allow me to complete my search uninterrupted.”

“The scheme worked perfectly.”

“Well, I knew when I came here that there was a casket concealed in a safe with a secret lock, and that the seven-of-hearts was the key to that lock. I had merely to place the card upon the spot that was obviously intended for it. An hour’s examination showed me where the spot was.”

“One hour!”

“Observe the fellow in mosaic.”

“The old emperor?”

“That old emperor is an exact representation of the king of hearts on all playing cards.”

“That’s right. But how does the seven of hearts open the larger safe at one time and the smaller safe at another time? And why did you open only the larger safe in the first instance? I mean on the night of 22 June.”

“Why? Because I always placed the seven of hearts in the same way. I never changed the position. But, yesterday, I observed that by reversing the card, by turning it upside down, the arrangement of the seven spots on the mosaic was changed.”

“Parbleu!”

“Of course, parbleu! But a person has to think of those things.”

“There is something else: you did not know the history of those letters until Madame Andermatt---”

“Spoke of them before me? No. Because I found in the safe, besides the casket, nothing but the correspondence of the two brothers which disclosed their treachery in regard to the plans.”

“Then it was by chance that you were led, first, to investigate the history of the two brothers, and then to search for the plans and documents relating to the sub-marine?”

“Simply by chance.”

“For what purpose did you make the search?”
