This book promises the truth behind the century's most celebrated murder mystery. On a wintry night in November 1974, Sandra Rivett, nanny to the children of Lord and Lady Lucan, was brutally bludgeoned to death in the basement of their Belgravia home. Lady Lucan was also attacked and identified the attacker as her estranged husband, the 7th Earl of Lucan. That night, Lord Lucan vanished and has never been found, despite numerous sightings all over the world. The author has interviewed many of those involved, including, for the first time, Lord Lucan's wife Veronica. He gained access to the missing Earl's private papers, which yield remarkable new information. He also re-examines the forensic evidence and questions the key witnesses to produce the most likely explanation to date of what really happened on November 7, 1974. Illustrated with black and white photographs.
