Breathtakingly real and utterly compelling, Immoral dishes up page-turning psychological suspense while treating us lucky readers to some of the most literate and stylish writing you'll find anywhere today.

We have years to converse with someone, to blurt and rant, to explain our desires and anger and regrets - and oh how we squander those moments.

For me a thriller is a very carefully structured story.

I also try very hard to create characters - both heroes and villains - with psychological depth.

Certainly going back to Sherlock Holmes we have a tradition of forensic science featured in detective stories.

Ideally, I like to integrate the human issues into the suspense story itself.

It means working harder to do the research but I don't really mind - I don't think I have what it takes to chase criminals through back alleys and wade through blood at crime scenes.
