Characters in novels are all fiction like the world they live in. Of course Vivien Lash has things in common with me but if she actually was me I wouldn't have been able to invent her. And I'm not plotting to murder my husband!
The closest connection between me and my characters is that we live in a city that's recognisable as London, but it's a version of London that came out of my head.
