Irvine Welsh is a Scottish novelist, short story writer, screenwriter and filmmaker. His work is closely tied to Scotland, where many of his novels and stories are set, and he is known for writing about working-class life.

Those themes recur across his novels and short stories, which focus on the pressures and details of everyday life in working-class Scotland.
