ENTERTAINMENT WEEKLY: I believeThe Family Upstairsmarks a full 20 years of being a published novelist for you.
Then I sort of realized that it wasnt 1998 at all, that it was 1999.
And then I forgot all about it.
So thank you for alerting me to the fact.
I think I might have to demand a party of some kind!
Its been very pure and positive.
I had a massive bestseller in 1999!
with my very first novel.
My name was kind of tainted in a way.
The Family Upstairsis another tale of dark family secrets.
And the beauty of writing about families with dark secrets is that families can be everywhere and anywhere.
And I love to write about houses.
Family is where every story in the world starts out.
Family is the crucible of all stories.
Whats the inspiration for Libby, Lucy, and Clemency?
Clemency is just a sidekick with a cool name, really.
What authors inspire you?I love Clare Mackintosh, Louise Candlish, Sabine Durrant, Tamar Cohen.
They never let me down.
But generally speaking it is individual books that inspire me rather than particular authors.
Any time I read an amazing book, Im inspired, regardless of who wrote it.
Whats the secret to delivering a good twist?
How did you come up with some of your favorites?Im terrible at twists.
