El intruso

The story opens on a cold, mist‑filled dawn in the mining district of Gallarta, where Dr. Luis Aresti awakens to the urgent summons of his housekeeper, Kataliñ. A corpse has been discovered on the road to Ortuella, the slain night‑school teacher known as “El Maestrico,” a killing that the locals instantly label a passion‑driven crime. As the doctor dons his heavy coat and his trusted walking stick, the bleak landscape of slag‑strewn hills and relentless wind mirrors the uneasy atmosphere of a community caught between poverty and the looming power of the mines.

Aresti is a figure both revered and resented: a well‑educated physician with ties to the enigmatic industrial magnate Sánchez Morueta, whose influence stretches from the pitheads to the corridors of Bilbao. The doctor’s recent dinner with affluent contractors has left him navigating a fragile balance between the miners’ grudging respect and the elite’s patronising generosity. With the body lying cold on the road and whispers of old rivalries swirling, Aresti sets out, his “cachaba” striking the ground, unaware of the deeper secrets the valley may soon reveal.
