Javier, a scriptwriter for scientific programs on the Network radio station, unexpectedly receives an offer to take part in a program dedicated to a book about Einstein. The program ends in scandal. Its participants have different points of view on the question: why, after his famous discoveries made at the beginning of his scientific career, did Einstein not make his “last answer” public at the end of his life? Why did he burn his scientific works before his death? Immediately after the transfer, the hero receives from an unknown person an envelope with an old postcard and the only phrase: “The last answer really exists.” At first it seems to Javier that this is a stupid prank, but when Einstein’s biographer, who lives at the address indicated on the postcard, is killed, he realizes that everything is more than serious...
