“Every kind of book I've written has been written in a different way. There has not been any set time for writing, any set way, I haven't re-invented the process every time but I almost have.”

Scottish novelist and playwright of the late 20th and early 21st centuries, Welsh is best known for his sharp, unflinching depictions of working-class life in Glasgow. His debut novel, *Trainspotting*, became a defining work of contemporary British literature, blending dark humor with raw social commentary. His later works, including *Filth* and *The Acid House*, continue to explore similar themes with equal intensity.
