How the U.S. Ambassador Was Spied on for 7 Years with an Invisible Bug—and Its Surprising Link to Electronic Music

In 1945, Soviet spies scored a major victory over their American colleagues: they managed to install a bug in the office of the American ambassador and secretly listen in on all conversations for several years. This innovative device, which had no analogues at that time, was born in the dungeons of the NKVD special prison for scientists and designers, the "Tupolev sharashka". The elusive bug was created by the father of electronic music and a real celebrity in the USA - and then a prisoner of conscience and an involuntary assistant of Soviet intelligence, Lev Termen.
