"Mr Steadfast" continues the adventures of Richard Hannay, whose earlier exploits are recounted in "The Thirty-Nine Steps" and "Greenmantle."PJohn Buchan's 100 works include nearly thirty novels and seven collections of short stories, as well as biographies of Sir Walter Scott, Caesar Augustus, and Oliver Cromwell. Buchan was awarded the James Tait Black Memorial Prize for his biography of James Graham, Marquess of Montrose, but the most famous of his books were the spy thrillers, and it is probably for these that he is now best remembered.
