What must have happened was that our devices, not insulated against things of which Dr. Korsakoff could have known little or nothing, had acted like copper wires in the distribution of electrical energy. The Sixth Dimension beam, then, must have been carried along with our own to strike at us in our own distant plane. Why tell of what followed--my apprehension for the crime and my conviction? Now, dear world of which I am but a miserable outcast, praying for death to relieve me of my suffering, let me close this chapter in my book of life. If any story succeeds in reaching the world, the world itself will know and believe that I, Arnoldi Kherkoff, did not murder my beloved benefactor, Dr. Ivan Korsakoff, as the courts of Russia believed. His was a murderer far beyond powers of man to apprehend. I suffer for the deed of a being in the Red Dimension--but not for long! I have little fear of the penalties exacted against prisoners of the camp for communicating with the outside world! When they learn of it, life will have already flown. * * * * * THE AUTHOR After an exciting career as a newspaper man, Ed Earl Repp began writing science fiction back in 1929. When his story "The Radium Pool" appeared in _Science Wonder Stories_, the following was written by the editor: "Perhaps it is a bit unethical for the editor to wax enthusiastic about any story, but we certainly could not help mentally applauding when we read _The Radium Pool_." Since that time Mr. Repp has had several hundred fantasy stories published in all the science fiction magazines, including _Amazing Stories_, _Planet Stories_, etc., and still receives fan mail asking for a sequel to _The Radium Pool_ and others of his works. In addition to his fantasy writing Mr. Repp has written and had published over 1500 fiction stories of all types in all the leading pulp magazines. He has authored eighteen books published in the United States, England, Australia, etc., and some of his novels have been reprinted in paper-backed editions. Mr. Repp has over eighty-five screenplay credits written for Warner Brothers, Columbia, Eagle Lion and others and is at present employed in his writing capacity by R. K. O. Studios in Hollywood. Ed Earl Repp is hailed as one of the leading magazine fiction writers in the country, specializing in action stories of western fiction and kindred subjects. One of the stories in this volume, _The Red Dimension_, has stood the test of time well enough to be nominated for SCIENTIFICTION'S HALL OF FAME and was reprinted as such in the summer 1945 issue of Startling Stories. Mr. Repp has been a member of numerous scientific expeditions into various parts of the country, and is widely traveled. His leading hobbies include archaeology, geology and paleontology. He is a resident of Sherman Oaks, California. _Books by Ed Earl Repp_
