Joseph McCabe,
The Romance of the Romanoffs
“ In 1716, Alexis being now twenty-six years old, the Tsar peremptorily bade him enter the monastery at Tver or join the army. He replied that he was coming to Russia, and he begged to be allowed to bring his latest passion, a young lady named Euphrosyne. After a short delay Peter heard that Alexis and Euphrosyne had fled, and in a terrible rage he sent his agents over Europe in search of his son. They traced him and his lady to an ancient castle in Austria. ”
