When I was ten or eleven I read this series of children’s books in Urdu featuring a boy who travels with snake charmers and has a pet snake. He and his snake have many adventures. Subsequently I dreamed about becoming besties with a snake or two for years. I’ve been fascinated by them ever since. The Indian subcontinent, of course, has many myths about snakes who assume human shape after a hundred years. I wanted to write a story about that. The research and details naturally followed.

I wanted Miriam to outgrow her mother, to come to the realization that her mother’s dictates are entirely arbitrary and based on some drama that has no basis in reality except in her mother’s mind. The problem is that when you finally shed someone else’s storyline, something you have been living within your entire life, what do you replace it with?

This is kind of weird, but I have these half-waking anxiety dreams about spiders descending from the ceiling onto me while I’m sleeping, to the point where I wake up in a panic, convinced there is actually a spider in my bed. So you’ll see spiders appear here and there in my fiction, although I wouldn’t say I’m arachnophobic, exactly. It’s just really creepy when they’re dangling on their threads, tiny legs working . . . ugh!

Many years ago, when I lived and worked in Sequoia National Park, I worked ten days and had four days off. Sometimes, I could run those four days together so I had eight days off to go hiking. I was on such a trip once when I realized I was being followed by a young couple from Germany on the same trail. We didn’t walk together, but we were in shouting distance of each other. Eventually, a man passed me going in the other direction. What was it about him? I’ll never know. He sent a cold shiver down my spine, and I remember thinking how glad I was that those other two were close behind.

So many of us think of a home as a living and breathing place. A house is witness to all of the good and all of the bad. Knowing what goes on behind our own closed doors and shuttered windows, we can only guess at what happens with our neighbors. So I wondered, if a house did have a soul and if a home is inherently good, then how would bad things affect it? How would a home exhibit PTSD? Would it co-opt the residents and use them? Was that the visible symptom?

I think most readers can relate to, or find the horror in, forgetfulness to some degree because, as you say, we deal with these things in real life. Losing a loved one to a disease like Alzheimer’s, even as they’re still with you physically—that’s scary for a lot of people. I suppose loss of memory for me means loss of identity. Without the accumulation of memories to inform and shape us, who are we? Why do we act the way we do? Personally, like the narrator, I would be scared of forgetting my own name.

I originally conceived of this story a few years ago, as a short audio drama. I was listening to a lot of podcasts then, and I think the idea was synthesized from days of listening to The Heart, Knifepoint Horror, and Limetown. Around that same time, my mom moved to an old farmhouse. To get there, you have to drive down a long, creepy dirt road, complete with an old graveyard. So I started from a particular scene on that dirt road: two characters in a car, and one of them unintentionally starting to drive dangerously fast. The story spun out from there

I’ve always liked shadow stuff. I’m the last person alive who doesn’t play video games, so I can’t draw any examples from that medium, but I’m generally into shadows, reflections, non-supernatural doppelgängers, changelings, people’s own skeletons as independent from themselves, that sort of thing. I feel like I ran into a lot of good shadow stuff in the books of my childhood, and that’s why I like it in the first place, but I’m too far removed from them to remember specific examples.

I’m very much drawn to folklore and fairy tales, possibly because I used to adore Hans Christian Andersen’s fairy stories when I was little. They were my first love in terms of books. If I go on holiday, I like to read about the folklore of the area—I like to think it enhances a landscape with the sense of layers of story living within it (though I might just be getting carried away). There’s something magical about drawing on that story pool, and I think that’s why I love it—folklore tells us about the world, but at the same time imbues it with something “other,” and keeps a sense of mystery at its heart.

If any genre has a history of inexplicable events that exist only to bring extremes of human nature into sharp relief, it’s horror. Night of the Living Dead actually offers a few lines of lame explanation as to why corpses suddenly became ambulatory, but that explanation was a vestigial remnant of the radiation-based horror movies of the 1950s, and was quickly abandoned by the sequels, as well as by the hundreds of iterations the film inspired. You don’t need to know why. It happened.
