Read this article in Filipino, Doktor Satan
Doktor Satan is a novel written by Mateo Cruz Cornelio. The story revolves around the dual-effect brought about by a scientific invention to a doctor and his patient. It tells about how Dr. Alberto Estrella tries to cure his mother from a serious illness and how he tries to make a new drug that would hopefully make her mother perfect in health. Alberto succeeded in his attempts of making a new drug when he experimented it and brought a Russian who committed suicide back to life. Alberto also wanted to have immortality so he drank his own creation but the effect was not the same as the Russian - he turned into something that resembles a devil, with fangs, horns and red eyes. This evil creature eventually killed Nena, who was Alberto's love. The story ended when Pepe accidentally killed Dr. Satan when he tried to murder the boy. Meanwhile, Alberto's mother was cured of her sickness.
