Dr. Nikola — Guy Newell Boothby

Of the Dr. Nikola series John Clute writes: "The heart of the series is devoted to the Doctor's convoluted search for a Tibetan process that will resuscitate the dead and ensure immortality in the living, and there are some hints that â€" unhampered by compunctions, armed with psi powers and blessed with a powerful experimental intellect â€" he may have reached his goal."
