“Great Black Wave” began with the ending, and nothing like its final form. All of the wider context, the bomb disposal team, the robot, the Afghanistan setting, grew out of that. In that sense—and I suppose this is always the case to some extent—the particular themes and background were a combination of pragmatism and my own preoccupations. A bomb disposal robot and rural Afghanistan as a location were an interesting way into the tale I wanted to tell.

“The Lost” is one of my earliest genre efforts. I’d gotten out of Columbia for my MFA not long before, and finally felt free to experiment. Columbia’s a lot more open-minded now, but back then genre wasn’t permitted. So I tinkered a lot—trying to figure out the line between literary and genre, between symbolic loss and real loss, and how to show that. Turns out, there are no rules, right?

I’d gone to the Oakland Museum and seen the original of the photograph Migrant Mother, by Dorothea Lange. It’s a very powerful portrait of a woman migrant during the Depression, and for some reason I’d never seen it before, and it really haunted me. Then I started thinking about the Depression, and how horrible it must have been to be confronted with two catastrophes at once: the Dust Bowl and the failure of the banks.

Whenever I come across a new form, I’m always curious to see how it might be bent to fictional ends. And horror has a long history of using the most novel means of communication to create unexpected shocks. Dracula, for example, used letters, telegrams, diary entries, and wax recordings to stitch together a dark tapestry of unease. Blair Witch Project employed apparently unedited documentary style footage to disturb the audience. And so on.

“The Old Horror Writer” was an anxiety story. I publish frequently, but you cannot say that I’m bestriding the literary world like a colossus. From time to time, I have dark thoughts about whether I’m wasting my effort, or where I’ll end up on the day the words stop coming. So I set up a character who was very specifically a version of myself and filled his tale with my bleakest musings about this endeavor that’s consumed my life, and its relevancy to the fate of this beleaguered planet.

The most obvious inspiration for the story, of course, is The Boy Who Came Back From Heaven, which is a nonfiction account by Kevin Malarkey and his son Alex (that’s really their last names . . . you can’t make this stuff up) where they claim that Alex saw Heaven while he was a in a coma. The boy later recanted, saying his dad had planted the whole story in his mind, and it was a huge mess, but for a while it was quite a cultural phenomenon. There was even a major studio picture, starring Greg Kinnear.

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.
