"It is nothing," I said with false casualness, and was returning it to my pocket. The worst of me is that I have no histrionic instinct; I cannot act a part.

"Wait!" she cried sharply, and I hesitated before the appeal in her tragic voice. "You cannot deceive me, Mr. Foster. It is something. I entreat you to read to me that letter. Does it not occur to you that I have the right to demand this from you? Why should he beat about the bush? You know, and I know that you know, that there is a mystery in this dreadful death. Be frank with me, my friend. I have suffered much these last days."

We looked at each other silently, I with the letter in my hand. Why, indeed, should I treat her as a child, this woman with the compelling eyes, the firm, commanding forehead? Why should I pursue the silly game of pretence?

"I will read it," I said. "There is, certainly, a mystery in connection with Alresca's death, and we may be on the eve of solving it."

The letter was dated concurrently with Alresca's will—that is to say, a few days before our arrival in Bruges—and it ran thus:

"My dear Friend:—It seems to me that I am to die, and from a strange cause—for I believe I have guessed the cause. The nature of my guess and all the circumstances I have written out at length, and the document is in the sealed packet which accompanies this. My reason for making such a record is a peculiar one. I should desire that no eye might ever read that document. But I have an idea that some time or other the record may be of use to you—possibly soon. You, Carl, may be the heir of more than my goods. If matters should so fall out, then break the seal, and read what I have written. If not, I beg of you, after five years have elapsed, to destroy the packet unread. I do not care to be more precise.

Always yours,
"Alresca."

"That is all?" asked Rosa, when I had finished reading it.

I passed her the letter to read for herself. Her hand shook as she returned it to me.

And we both blushed. We were both confused, and each avoided the glance of the other. The silence between us was difficult to bear. I broke it.
