In her memoirs the artist Elizaveta Lavinskaya, a friend of Briks and Mayakovsky, mentions that at some point new persons started visiting the LEF meetings, including Yakov Agranov, Zakhar Volovich and some other people later identified as high-ranking NKVD officers. A number of people also speculated about the sexual relationships between Lylia and Agranov, including the acclaimed Soviet ballet dancer Maya Plisetskaya in her book. However, film director , the son of Lylia's third husband Vasily Katanyan, claimed that Brik personally denied those "fantasies" that "started circulating after Agranov's execution".
