Metro interview of Tom Rob Smith

Today's Metro has Tom Rob Smith in its '60 Second Interview' slot. The much publicised Child 44 is out next week:

Why all the excitement about Child 44?
It’s hard to say why. I tried to make it as entertaining as I could, but I didn’t think it would sell around the world – that’s come as a surprise. I didn’t think it was very commercial. It’s set in Russia in the 1950s and some people have told me they found that interesting and thought the detective story was exciting, but I didn’t have a formula for writing it.
