My first solo novel, Snow Storms In A Hot Climate was born out of a
trip I took to South America in the late 1970s, when rucksack
travelling threw me into some interesting company at a time when the
cocaine trade was moving from amateur hands into those of the cartels.
I think the best way to describe it is as a thriller about addiction:
to love, to friendship and to the adrenaline that comes with living
your life in the fast lane.
The first appearance of Hannah Wolfe, an English private eye designed
(at the time) to give her American counterparts, VI Warshawski and
Kinsey Millhone, a culturally different run for their money. The story
about surrogacy and motherhood was a way to mix the political with the
personal, since underneath the plot was the fact that I had just had my
first child and was trying to make sense of what it meant. (Or didn’t). 
Questioning cosmetic surgery now seems like finding reasons to
challenge the proliferation of oil-fuelled cars in the 1920s. But I did
-- and still do -- question cosmetic surgery. I was working in
television at the time, and Hannah Wolfe’s third (and last) outing had
much to do with our obsession with beauty and conformity, and what
women are willing to do to achieve it.
The darkest of all the books I have written. It tells the story of a
woman living alone in a rambling house in north London in which strange
things start to happen (scratch any novel and you find not only the
writer’s fears but perhaps even the house she lives in). What takes
place when she realises exactly what or who is intruding in her house
is something that may be tough to read but I stand by it completely. I
wanted to write a novel that would punch an imaginative hole through
women’s fears (made worse by the culture around them) that they are
always at threat from male violence and that they will be destroyed by
it. Challenging this in your mind is the first step to defeating it in
reality. That, it seems to me, is part of the power of fiction.
Or what happens when someone you love goes missing. This is the book
that made me realise I was probably ready to stop writing thrillers. I
was so keen to make it truthful -- or rather to accept that in life
there is never just one single truth, and that thrillers are often too
keen to wrap everything up in a big red bow at the end. The story tells
parallel versions of what might be happening to Anna -- who has left
her friends and young daughter for a weekend in Italy -- while studying
the effects of her absence on those who love her. Some people love it.
Some people find it frustrating. There is one sentence I would now
change. But one writes (and lives) to learn...
My aim was a grand one: to bring alive this most amazing of cities
during the moment of its greatest drama and cultural triumph, and to
make the Renaissance vital for a popular audience, rather than a few
pages in a school history book. The story of Alessandra, a young woman
born into a merchant’s family in Florence in the 1480s and in love with
the art around her, took me back to my first great passion, which was
history. The novel changed many things in my life -- including the
future of my writing.
From Florence to Venice. This, the second of my novels set in the
Renaissance, grew out of Titian’s great portrait that has come to be
known as ”the Venus of Urbino” (a detail of which is on the cover). The
naked model was almost certainly a courtesan living in Venice at the
time and it was courtesan culture that so interested me. But I think
what made the novel different and such a challenge for me was its
narrator: a 30-year-old male dwarf who works as the courtesan’s
companion and manager. I had never written from inside the mind of a
man before, and I loved it. It also gave me the chance to look at the
thriving culture of sin and desire at a time when the Catholic church
was at its most corrupt.
