John Buchan was a prolific author, and can be fairly called the father of the modern thriller genre. Enduringly popular, many of his books have never been out of print: and yet serious critics have had little to say about him, although contemporary writers such as Graham Greene were appreciative of his work. Christopher MacLachlan's SCOTNOTE study guide provides a thorough overview and critical appraisal of three Buchan novels, substantially set in Scotland, for senior school pupils and students at all levels.
