I'm writing my BA thesis on Philip K. Dick's Do Androids Dream of Electric Sheep?. In the Polish translation of the book, there is an indication that an android needs to kill its owner to get from Mars to Earth. Referencing this assertion would improve my thesis greatly, but I cannot find the corresponding statement in the English version of the book.
Can someone please give me some indication on where in the text it can be found, or some other information regarding this assertion?
