In 1927 two young scientists were discovered dead in the Asian jungle. Siegmund and Sieglinde were brother and sister, heirs of a Scandinavian physician couple known for performing whimsical experiments on their patients. It has been hypothesized that they were left by their parents with a ‘forbidden experiment’, possibly with their own sister. Neither her body nor the body of their parents were ever found. But we have traces of their existence in the logs the 2 scientists separately kept.
