The authors claim to have discovered that the Bolshevik execution of the Romanov family in July 1918 killed only the Tsar, while the Tsarina and her daughters remained alive until at least December 1918, after which on one knows what became of them. Lenin allegedly wanted to keep the German-born Tsarina and the daughters alive as hostages during the threat of Reischwehr invasion beyond the Ukraine that summer (the hemophilic son seems to have caused no concern). The book's major source is a seven-volume dossier compiled by Nikolai Solokov, a White general, which the authors tracked from Mayfair to a Cincinnati Bell Telephone executive and finally found in. . .the Harvard library. Sokolov's material provided backing for their view although he himself concluded that all the Romanovs were executed. Two other documentary sources were a moot visit to the Anastasia pretender, a frail, pleasantly schizophrenic woman living in Virginia, and the testimony of the Tsar's major domo, which reinforced the authors' hypothesis. The book has been used for a BBC feature; as the authors ruefully admit, even George V of England, Nicholas' cousin, was utterly indifferent to the Romanovs' fate, but certain plebians do retain a fascination with the case.
