The surgeon quickly raised his eyes and saw the four officers, and for a moment fear paralyzed his arm.

"The police!" he gasped.

Then, with a look of redoubled fury, he sent the knife to the hilt into the squirming mass before him. The wounded monster sprang to its feet and wildly threw its arms about, meanwhile emitting fearful sounds from a silver tube through which it breathed. The surgeon aimed another blow, but never gave it. In his blind fury he lost his caution, and was caught in an iron grasp. The struggling threw the lamp some feet toward the officers, and it fell to the floor, shattered to pieces. Simultaneously with the crash the oil took fire, and the corridor was filled with flame. The officers could not approach. Before them was the spreading blaze, and secure behind it were two forms struggling in a fearful embrace. They heard cries and gasps, and saw the gleaming of a knife.

The wood in the house was old and dry. It took fire at once, and the flames spread with great rapidity. The four officers turned and fled, barely escaping with their lives. In an hour nothing remained of the mysterious old house and its inmates but a blackened ruin.

An Original Revenge

On a certain day I received a letter from a private soldier, named Gratmar, attached to the garrison of San Francisco. I had known him but slightly, the acquaintance having come about through his interest in some stories which I had published, and which he had a way of calling "psychological studies." He was a dreamy, romantic, fine-grained lad, proud as a tiger-lily and sensitive as a blue-bell. What mad caprice led him to join the army I never knew; but I did know that there he was wretchedly out of place, and I foresaw that his rude and repellant environment would make of him in time a deserter, or a suicide, or a murderer. The letter at first seemed a wild outpouring of despair, for it informed me that before it should reach me its author would be dead by his own hand. But when I had read farther I understood its spirit, and realized how coolly formed a scheme it disclosed and how terrible its purport was intended to be. The worst of the contents was the information that a certain officer (whom he named) had driven him to the deed, and that he was committing suicide for the sole purpose of gaining thereby the power to revenge himself upon his enemy! I learned afterward that the officer had received a similar letter.

This was so puzzling that I sat down to reflect upon the young man's peculiarities. He had always seemed somewhat uncanny, and had I proved more sympathetic he doubtless would have gone farther and told me of certain problems which he professed to have solved concerning the life beyond this. One thing that he had said came back vividly: "If I could only overcome that purely gross and animal love of life that makes us all shun death, I would kill myself, for I know how far more powerful I could be in spirit than in flesh."

The manner of the suicide was startling, and that was what might have been expected from this odd character. Evidently scorning the flummery of funerals, he had gone into a little canyon near the military reservation and blown himself into a million fragments with dynamite, so that all of him that was ever found was some minute particles of flesh and bone.

I kept the letter a secret, for I desired to observe the officer without rousing his suspicion of my purpose; it would be an admirable test of a dead man's power and deliberate intention to haunt the living, for so I interpreted the letter. The officer thus to be punished was an oldish man, short, apoplectic, overbearing, and irascible. Generally he was kind to most of the men in a way; but he was gross and mean, and that explained sufficiently his harsh treatment of young Gratmar, whom he could not understand, and his efforts to break that flighty young man's spirit.
