I love a mystery, and cosmic horror is a place where the mysteries are never fully solved. The persistence of our curiosity about monstrous cosmic indifference, or malice, is part of the thrill. Writing this story, I fixated on Carcosa, on the challenge of making it into a compelling character.

I first visited Haw Par Villa as a kid. Weirdly, I was most afraid of the exhibit that shows the “good souls” standing on the silver and gold bridges to cross into paradise. For some reason I interpreted that exhibit to mean that the good souls would be standing on that bridge forever.

I think both the inspector and Gemma are characters who find solace in each other because they are trying to mediate these brutal social forces that they didn’t choose, but were born into, which is something I relate to. How are you supposed to make decisions for yourself, or even just survive, when you inherit a world other people made for you?

I live near the Greenwich Peninsula, which is an area of London crammed full of new-build blocks of luxury apartments, some of which (particularly during the COVID lockdowns) seemed almost entirely empty. I would often notice a single light in the stairwell.
