and locks. No doubt, the Varin brothers were aware of that fact and utilized one of Lacombe's safes in which to conceal the letters.... and other things, perhaps."
"But they did not live here," I said.
"Before you came, four months ago, the house had been vacant for some time. And they may have thought that your presence here would not interfere with them when they wanted to get the papers. But they did not count on my husband, who came here on the night of 22 June, forced the safe, took what he was seeking, and left his card to inform the two brothers that he feared them no more, and that their positions were now reversed. Two days later, after reading the article in the `Gil Blas,' Etienne Varin came here, remained alone in this room, found the safe empty, and.... killed himself."
After a moment, Daspry said:
"A very simple theory....Has Mon. Andermatt spoken to you since then?"
"No."
"Has his attitude toward you changed in any way? Does he appear more gloomy, more anxious?"
"No, I haven't noticed any change."
"And yet you think he has secured the letters. Now, in my opinion, he has not got those letters, and it was not he who came here on the night of 22 June."
"Who was it, then?"
"The mysterious individual who is managing this affair, who holds all the threads in his hands, and whose invisible but far-reaching power we have felt from the beginning. It was he and his friends who entered this house on 22 June; it was he who discovered the hiding-place of the papers; it was he who left Mon. Andermatt's card; it is he who now holds the correspondence and the evidence of the treachery of the Varin brothers."
"Who is he?" I asked, impatiently.
"The man who writes letters to the `Echo de France'.... Salvator! Have we not convincing evidence of that fact? Does he not mention in his letters certain details that no one could know, except the man who had thus discovered the secrets of the two brothers?"
"Well, then," stammered Madame Andermatt, in great alarm, "he has my letters also, and it is he who now threatens my husband. Mon Dieu! What am I to do?"
"Write to him," declared Daspry. "Confide in him without reserve. Tell him all you know and all you may hereafter learn. Your interest and his interest are the same. He is not working against Mon. Andermatt, but against Alfred Varin. Help him."
"How?"
"Has your husband the document that completes the plans of Louis Lacombe?"
"Yes."
"Tell that to Salvator, and, if possible, procure the document for him. Write to him at once. You risk nothing."
The advice was bold, dangerous even at first sight, but Madame Andermatt had no choice. Besides, as Daspry had said, she ran no risk. If the unknown writer were an enemy, that step would not aggravate the situation. If he were a stranger seeking to accomplish a particular purpose, he would attach to those letters only a secondary importance. Whatever might happen, it was the only solution offered to her, and she, in her anxiety, was only too glad to act on it. She thanked us effusively, and promised to keep us informed.
In fact, two days later, she sent us the following letter that she had received from Salvator:
"Have not found the letters, but I will get them. Rest easy. I am watching everything. S."
I looked at the letter. It was in the same handwriting as the note I found in my book on the night of 22 June.
Daspry was right. Salvator was, indeed, the originator of that affair.
We were beginning to see a little light coming out of the darkness that surrounded us, and an unexpected light was thrown on certain points; but other points yet remained obscure—for instance, the finding of the two seven-of-hearts. Perhaps I was unnecessarily concerned about those two cards whose seven punctured spots had appeared to me under such startling circumstances! Yet I could not refrain from asking myself: What role will they play in the drama? What importance do they bear? What conclusion must be drawn from the fact that the submarine constructed from the plans of Louis Lacombe bore the name of `Seven-of-Hearts'?
Daspry gave little thought to the other two cards; he devoted all his attention to another problem which he considered more urgent; he was seeking the famous hiding-place.
"And who knows," said he, "I may find the letters that Salvator did not find—by inadvertence, perhaps. It is improbable that the Varin brothers would have removed from a spot, which they deemed inaccessible, the weapon which was so valuable to them."
And he continued to search. In a short time, the large room held no more secrets for him, so he extended his investigations to the other rooms. He examined the interior and the exterior, the stones of the foundation, the bricks in the walls; he raised the slates of the roof.
One day, he came with a pickaxe and a spade, gave me the spade, kept the pickaxe, pointed to the adjacent vacant lots, and said: "Come."
I followed him, but I lacked his enthusiasm. He divided the vacant land into several sections which he examined in turn. At last, in a corner, at the angle formed by the walls of two neighboring proprietors, a small pile of earth and gravel, covered with briers and grass, attracted his attention. He attacked it. I was obliged to help him. For an hour, under a hot sun, we labored without success. I was discouraged, but Daspry urged me on. His ardor was as strong as ever.
At last, Daspry's pickaxe unearthed some bones—the remains of a skeleton to which some scraps of clothing still hung. Suddenly, I turned pale. I had discovered, sticking in the earth, a small piece of iron cut in the form of a rectangle, on which I thought I could see red spots. I stooped and picked it up. That little iron plate was the exact size of a playing-card, and the red spots, made with red lead, were arranged upon it in a manner similar to the seven-of-hearts, and each spot was pierced with a round hole similar to the perforations in the two playing cards.
"Listen, Daspry, I have had enough of this. You can stay if it interests you. But I am going."
Was that simply the expression of my excited nerves? Or was it the result of a laborious task executed under a burning sun? I know that I trembled as I walked away, and that I went to bed, where I remained forty-eight hours, restless and feverish, haunted by skeletons that danced around me and threw their bleeding hearts at my head.
Daspry was faithful to me. He came to my house every day, and remained three or four hours, which he spent in the large room, ferreting, thumping, tapping.
"The letters are here, in this room," he said, from time to time, "they are here. I will stake my life on it."
On the morning of the third day I arose—feeble yet, but cured. A substantial breakfast cheered me up. But a letter that I received that afternoon contributed, more than anything else, to my complete recovery, and aroused in me a lively curiosity. This was the letter:
"Monsieur,
"The drama, the first act of which transpired on the night of 22
June, is now drawing to a close. Force of circumstances compel me
to bring the two principal actors in that drama face to face, and I
wish that meeting to take place in your house, if you will be so
kind as to give me the use of it for this evening from nine o'clock
to eleven. It will be advisable to give your servant leave of
absence for the evening, and, perhaps, you will be so kind as to
leave the field open to the two adversaries. You will remember
that when I visited your house on the night of 22 June, I took
excellent care of your property. I feel that I would do you an
injustice if I should doubt, for one moment, your absolute
discretion in this affair. Your devoted,
"SALVATOR."
I
