JOHN BUCHAN (1875-1940) was a British novelist and historian who divided his time between writing adventure fiction and serving in various political and diplomatic positions, the most notable of which was as Governor General of Canada.

"Politics is like a chicken-coop, and those inside get to behave as if their little run were all the world."
-John Buchan, Greenmantle
