Volkov's memoirs, "Souvenirs d'Alexis Volkov", were published by Payot of Paris in 1928, a year before his death in 1929. Serge Ostrogorsky, a Russian courtier who knew Volkov, claimed after Volkov's death that Volkov had told him that Anderson was not Anastasia and that the encounter had moved him to tears, but also that he admitted that he had kissed her hand. Ostrogorsky claimed that he pressed Volkov to account for the hand-kissing, which "he would never have done if someone other than Grand Duchess Anastasia had been standing before him". At which point, according to Ostrogorsky, Volkov said, "I believe that she is the Grand Duchess, but how can the Grand Duchess speak no Russian?"
