CONTENTS: The Thirty-Nine Steps John Buchan wrote ''The Thirty-Nine Steps'' while he was seriously ill at the beginning of World War I. In it, he introduces his most famous hero, Richard Hannay, who, despite claiming to be an ''ordinary fellow'', is caught up in the dramatic race against a plot to devastate the British war effort. Hannay is hunted across the Scottish moors by police and a pitiless enemy in the corridors of Whitehall and, finally, at the site of the mysterious 39 steps. The best-known of Buchan's thrillers, this novel has been continuously in print since first publication and has been filmed three times. Greenmantle This novel continues the story of Richard Hannay, taking him from convalescence following the Battle of Loos, back to London for a vital meeting at the Foreign Office, and thence on a top-secret mission across war-torn German-occupied Europe. Mr. Standfast In Mr Standfast (1919), the third of the novels featuring Richard Hannay, we meet again Pieter Pienaar and John S. Blenkiron. It is 1917 and Hannay is brought out of the battlefield to perform the desperate task of tracking down and destroying a network of German spies. Hannay's opponent is Morton Ivery, the bland master of disguise, who seeks to outwit Hannay as he and his agents are pursued through England, Scotland, France, and Switzerland. For its pace and suspense, its changes of scene, and thrilling descriptions of the last great battles against the Germans, Mr Standfast offers everything that has made its author so enduringly popular.
