Aelita.

A mysterious radio message is beamed around the world, and among the engineers who receive it are Los, the hero, and his colleague Spiridonov. Los is an individualist dreamer. Aelita is the daughter of Tuskub, the ruler of a totalitarian state on Mars in which the working class are put into cold storage when they are not needed. With a telescope, Aelita is able to watch Los. As if by telepathy, Los obsesses about being watched by her.
