Without a trace?...
S1 E1/2. What's It All About? It's one of the most mysterious vanishing acts in modern British history, and a crime that has fascinated the public for nearly 40 years.
So it's no wonder ITV was able to assemble such an impressive cast, including Rory Kinnear, Christopher Eccleston and Michael Gambon, for this two-part drama about the events leading up to the disappearance of Lord Lucan - they are probably just as keen to discover what may have happened as the rest of us.
Written by the award-winning Jeff Pope, and based on the book The Gamblers by John Pearson, who gained unprecedented access to the flamboyant aristocrat's friends, it looks at Lucan's (Kinnear) exploits with the infamous Clermont Set, rich British gamblers who met at Mayfair's Clermont Club, as well as at the strains on his marriage.
As Lucan's relationship with his wife Veronica broke down, he became increasingly obsessed with gaining custody of his children. So when, in November 1974, the Lucans' nanny, Sandra Rivett, was found bludgeoned to death in the basement of the family's Belgravia home, it was widely assumed that her aristocratic employer had killed her after mistaking her for his wife. But how exactly did Lucan manage to elude the authorities?
Look Out For: The rest of that impressive cast, which includes Catherine McCormack as Veronica, and Gemma Jones as Lucan's mother.
Rory Kinnear says: "In many ways it's really a sad story of the domestic breakdown of a marriage involving two entirely unsuitable people, as well as the mystery of what happened to Lucan."
