Horn called up the detective, and together they read the following words:
“Dear Friend:—
“He challenged me—pistols—it means life or death. My enemy is very bitter. But I am not ready to die yet. And as I know that I would be the one to fall, I have refused the duel. That will help me little, for his revenge will know how to find me. I dare not be a moment without a weapon now—his threats on my refusal let me fear the worst. I have an uncanny presentiment of evil. I shall leave here to-morrow. With the excuse of having some pressing family affair to attend to, I have secured several days’ leave. Of course I do not intend to return. I am hoping that you will come here and break up my establishment in my stead. I will tell you everything else when I see you. I am in a hurry now, for there is a good deal of packing to do. If anything should happen to me, you will know who it is who is responsible for my death. His name is—”
Here the letter came to an abrupt close.
Muller and Horn looked at each other in silence, then they turned their eyes again toward the dead man.
“He was a coward,” said the detective coldly, and turned away. Horn repeated mechanically, “A coward!” and his eyes also looked down with a changed expression upon the handsome, soft-featured face, framed in curly blond hair, that lay so silent against the chair-back. Many women had loved this dead man, and many men had been fond of him, for they had believed him capable and manly.
The commissioner and Muller continued their researches in silence and with less interest than before. They found a heap of loose ashes in the bedroom stove. Letters and other trifles had been burned there. Muller raked out the heap very carefully, but the writing on the few pieces of paper still left whole was quite illegible. There were several envelopes in the waste-basket, but all of them were dated several months back. There was nothing that could give the slightest clue.
The letter written by the murdered man was sufficient proof that his death had been an act of vengeance. But who was it who had carried out this secret, terrible deed? The victim had not been allowed the time to write down the name of his murderer.
Horn took the letter into his keeping. Then he left the room, followed by Muller and the valet, to look about the rest of the house as far as possible. This was not very far, for the second story was closed off by a tall iron grating.
“Is the house door locked during the daytime?” asked Horn of the servant.
