Diana's on the hunt and has the perfect new target.

Finally, the type of wealth she's always dreamed of. A five-storey house in Hampstead, unfettered access to London's liberal elite and a bloated bank account.

If she can ensnare David Farrand, then she really will have clawed her way to the top.

The only snag? David's daughter, Cat.

Diana might have got her claws into David, but Cat is sharpening her own. Entitled, suspicious and used to getting her own way, she's been digging into Diana's past.

And it turns out Diana's last three marriages have one thing in common: the silly old fools are all six feet under.

To lose one husband is unlucky. To lose two is careless. But three? Three must be murder.
