Graham Masterton. It was a very interesting one, too, and I'd been thinking for a while that a longer interview would be worth doing. So I asked Graham if he'd be interested and he said yes!
The interview, for This Is Horror, touches on subjects such as research and the writing process, as well as Graham's Katie Maguire crime novels and his excellent novel Trauma (aka Bonnie Winter.) It's a pretty substantial length, so it's being published in two parts. The first is up at This Is Horror now.
