I went to an exhibition at our National Museum that exhibited artifacts from Australia’s bushrangers. In the middle of the room stood a large, solid wooden door, soft with age, riddled with bullet holes. One of Ben Hall’s gang had been shot and killed in front of this door. The bullet holes were distinctive, and I thought I saw bloodstains, and the image was so powerful I almost imagined his ghost, up against the door. I thought about other doors, and what happens behind them

There was genuinely a wonderful, evocative scent that haunted me in my teens. I’ve no idea if it was a perfume I smelt once on a passing stranger or something I conjured from my own imagination, but I could evoke it at will, and once I had, it would tantalize me for days. I really did travel into Moorgate on the train every day with my friends for school, and I was once taken to an air show by my Aunty Anne (who fed me far too many boiled eggs). I’ve known for years that there was a story somewhere to be built around this “ghost” scent.

The story sprang out of a small, lovely book I picked up at a yard sale—The Ladies’ Letter-Writer—published in Great Britain in the early 1900s. You can see similar volumes on Google Books, all of them harkening back to an era when we relied so much on written correspondence. The sample letters cover many common occasions such as marriages, births, and deaths. The tone is very calm, the circumstances sometimes heartbreaking.

This question of a mom-who-fights came back to me when I was working in the Buffy the Vampire Slayer universe. I kept imagining myself as Joyce out there with a bazooka. Joyce packed Buffy a sandwich; I would have packed her some hand grenades. When I wrote “Lady Madonna,” I didn’t have a daughter yet, but I wanted one. Some of my friends were so overprotective of their children that I just spun the story out to the extreme.

Horror is the fiction of worst-case scenarios. And the art is in giving it a mythic, symbolic, resonantly recognizable image to grapple with. A monster, a shadow, a mirror reflection. A something. And we face it, then deal with it or don’t. As for literalization—if I understand what you’re asking correctly—yeah, I tend to wade in face-first with a wide angle lens, shooting the dream in my head with as much intense visual specificity as possible.
