The first sign was not a collapse. It was a door that would no longer close. In an ordinary East Kent coal village, Mrs Hargreaves has a problem with her house. A sticking front door. A crack above the bay window. A floor that is no longer quite where it used to be. When surveyor Daniel Reeve arrives with his level, crack gauge and careful language, what looks like a small domestic fault begins to point downwards into a deeper story. Beneath the village lies the memory of the East Kent Coalfield: pits, seams, wet shale, timber props, black dust, grey bathwater and men who worked where daylight could not follow. Ninety years earlier, Tom Hargreaves works underground at Snowdown, listening for the small dry tick of timber under pressure. Above him are fields, houses, roads and a future that does not yet know what has been removed beneath it. The Deep Seam is a Kent After Dark novella about homes, labour, subsidence and the stubborn force of ground that does not forget. It is not a ghost story in the usual sense. The haunting is weight. The surface thought the story was over. The seam knew better.
