Murder in the Fourth Dimension

Blurb

A scribbled note left by a tree was the only clue to two missing men...ExcerptNot everyone, perhaps, will believe that my ten years' hatred for Edgar Halpin was the impelling force that drove me to the perfecting of a most unique invention. Only those who have detested and loathed another man with the black fervor of the feeling I had conceived, will understand the patience with which I sought to devise a revenge that should be safe and adequate at the same time. The wrong he had done me was one that must be expiated sooner or later; and nothing short of his death would be sufficient. However, I did not care to hang, not even for a crime that I could regard as nothing more than the mere execution of justice; and, as a lawyer, I knew how difficult, how practically impossible, was the commission of a murder that would leave no betraying evidence. Therefore, I puzzled long and fruitlessly as to the manner in which Halpin should die, before my inspiration came to me.I had reason enough to hate Edgar Halpin. We had been bosom friends all through our school days and through the first years of our professional life as law-partners. But when Halpin married the one woman I had ever loved with complete devotion, all friendship ceased on my side and was replaced by an ice-like barrier of inexorable enmity. Even the death of Alice, five years after the marriage, made no difference, for I could not forgive the happiness of which I had been deprived-the happiness they had shared during those years, like the thieves they were. I felt that she would have cared for me if it had not been for Halpin-indeed, she and I had been almost engaged before the beginning of his rivalry.
