Which relative is looking for the man in Conway's basement?
At his psychiatric institute, Dr. Charles Conway is surreptitiously experimenting with artificial glands to try to create longevity; he works with his minion Lobo and his assistant Dr. Sharon Gilchrist. Conway receives his test subjects through an associate, Dr. Loren Wright, who delivers patients seeking treatment for lesser conditions. After this, they are then taken into the operating room for Conway's illicit surgery.
Wright delivers his newest find, Grace Thomas, who is seeking treatment for depression. When Conway balks at Wright for bringing him a patient with living relatives, he confides in Conway that he plans to throw Grace's purse and bags into the bay, to fool family and the authorities into believing she had committed suicide. He then asks Conway for a demonstration of his experimental progress; Conway takes him down into the basement, where he introduces him to Harry Jedrow, his latest victim. Jedrow is clearly alive, but severely disfigured and in a vegetative state; this concerns Wright, who reveals that Jedrow's sister is currently seeking him out. Conway is furious, since none of his patients were supposed to have ties of any kind.
That night, Lobo (who famously delivers the line "Time for go to bed!") discovers Frank Scott roaming around the grounds. Scott attempts to conceal his identity, but Conway quickly deduces that he is an escaped convict from his description in the newspapers, as well as a telltale tattoo on his wrist. Rather than turn Scott into the police, he offers him the chance to take part in his experiments. Knowing the odds are stacked against him, Scott accepts his offer.
