When the Tsar's eighteen-year-old niece Princess Irina Romanov announced her marriage to Prince Felix Youssoupov, heir to the richest fortune in Russia, the Imperial family were shocked. Prince Felix and his wife Princess Irina had it all. When they married in St Petersburg in 1914 immense wealth and social standing were theirs. But fate had other ideas. In 1916 Felix was involved in one of the most famous crimes of the twentieth century - the murder of Gregory Rasputin, evil genius of Empress Alexandra. It was Irina's royal blood that ensured Felix was never prosecuted for what many saw as a patriotic act. The following year revolution swept the country and in 1919 Felix and Irina were forced into exile for the rest of their lives. How did they survive in the real world when the money began to run out? Why did they live their lives in the shadow of Rasputin? How did Rasputin save them? And how did Felix redeem himself for Rasputin's murder? No joint biography of Irina and Felix has ever been written. This book utilises little-known Russian sources, as well as documents recently purchased at auction to reveal new facts, throwing fresh light on the couple's lives, their relationship and how they never quite escaped from the shadow of Rasputin.
