Might you also talk a bit about your writing process? Your daily process while you are writing as well as what is it like to write a series—keeping all those plot threads straight!

I’m very lucky that I have the kind of mind that is perfectly suited to writing fiction and which is horribly ill-suited to everything else. I take notes now and again and sometimes find scraps of paper with random words and aide-memoirs scribbled upon them but by and large I think of my skull like one of those candyfloss machines. I just swirl a stick around in there and ideas stick to it. The story I’m living and breathing then squats there in my head and pushes everything else out. Sometimes I look at the clock and I’ve lost a day and I realise I haven’t been to the bathroom since dawn. I write a chapter a day, no matter what. I’m at my desk by 9am, drinking coffee and grinding my teeth. It’s delightfully masochistic. I kind of enjoy the agony of it, which sounds very pretentious for a writer of dark thrillers! As soon as it’s done, my brain just kind of flatlines for a bit. Then it starts preparing for the next project. Two years later, when the book is in people’s hands, I’ve largely forgotten what it was about. Sorry!
