In 1957, a version of Anderson's story, pieced together by her supporters and interspersed with commentary by Roland Krug von Nidda, was published in Germany under the title "Ich, Anastasia, Erzähle" ("I, Anastasia, an autobiography"). The book included the "fantastic tale" that Anastasia escaped from Russia on a farm cart with a man called Alexander Tschaikovsky, whom she married and had a child by, before he was shot dead on a Bucharest street, and that the child, Alexei, disappeared into an orphanage. Even Anderson's supporters admitted that the details of the supposed escape "might seem bold inventions even for a dramatist", while her detractors considered "this barely credible story as a piece of far-fetched romance". Other works based on the premise that Anderson was Anastasia, written before the DNA tests, include biographies by Peter Kurth and James Blair Lovell. More recent biographies by John Klier, Robert Massie, and Greg King that describe her as an impostor were written after the DNA tests proved that she was not Anastasia.
