Visitors to Seeon included Prince Felix Yusupov, husband of Princess Irina Alexandrovna of Russia, who wrote, ""I claim categorically that she is not Anastasia Nicolaievna, but just an adventuress, a sick hysteric and a frightful playactress." I simply cannot understand how anyone can be in doubt of this. If you had seen her, I am "convinced" that you would recoil in horror at the thought that this frightful creature could be a daughter of our Tsar." Other visitors, however, such as Felix Dassel, an officer whom Anastasia had visited in hospital during 1916, and Gleb Botkin, who had known Anastasia as a child and was Tatiana Melnik's brother, were convinced that Tschaikovsky was genuine.
