Some rules survive because nobody remembers choosing them.

Horror rooted in the systems people learn to live with.

Andrew Calder writes about what happens when someone finally refuses the rule everyone else has learned to obey.

The fiction moves through Scottish lochs, stables, villages, theatres and failing institutions, places where old bargains have become routine enough to pass for common sense. The supernatural pressure matters, but it rarely arrives alone. Family obligation, public systems, private guilt and the desire to keep the peace are usually already waiting.

The books favour slow-building dread over explanation for its own sake. A place should feel real before it becomes frightening. A character should have something to lose before the story asks them to choose. When the choice is made, the consequences should remain visible.

Across the Courtesy Cycle, Harthollow, Blackshaw and The White Loch series, alongside standalone novels such as The Low Door of Dunure, The Mare in the Picture, No One Claps at Ballantrae, The Last Tent at Loch Trool and The Snow Below, the recurring question is less whether something supernatural exists than whether the ordinary people around it have already decided that living with it is easier than resisting.
