The victim in this bizarre roboticide mystery, Jander is Dr. Han Fastolfe's second successful humaniform robot. Jander is in the possession of Gladia Delmarre/Solaria when his positronic brain is permanently disabled. Fastolfe proudly insists that he is the only person who has the knowledge and skill needed to do this, but resolutely denies having done so. He considers it a fluke. Earth Plainclothesman Elijah Baley examines the body, which shows no signs of decay as would a human, and notes that the genitals are perfectly represented. He surmises that Jander is Gladia's lover and she confesses that it is more: they consider one another husband and wife. Jander cannot receive pleasure but is dedicated to giving it to Gladia, thus helping her overcome a wretched sex life. Jander's loss leaves her desolate. In the end, it is determined that R. Giskard Reventlov, a normal-looking metallic robot that has the ability to read and influence human and robotic minds, disables Jander to thwart Dr. Kenden Amadiro's plans to use humaniform robots exclusively to colonize other worlds.
