On a winter's night in 1974, a crime took place that would obsess the nation.

It was an extraordinary news story.

The story of an aristocrat, Lord Lucan, who's said to have killed the family Nanny,

putting it off putting it off and dodging the subject and changing the subject.

And I said him, at least I'll make it easier for you if he pay so much every month, if you are unable to pay it all.

He only paid $600,000 and still $400,000 outstanding.
