This novel, set more than a century ago in backwater South Africa, is the great grandfather of today's thrillers. Buchan, who perfected the form in "The 39 Steps" some years later, gives his young hero plenty to do in sussing out and confronting a massive uprising by tribesmen who wish to slaughter all the white settlers for a hundred miles around. Read it and be taken back to another time and another place-- it feels totally contemporary in terms of its "Indiana Jones" adventure plot.

In 1910 British novelist and politician John Buchan used the medieval legend of Prester John in his sixth book, Prester John, to supplement a plot about a Zulu uprising in South Africa. This book is an archetypal example of the early 20th-century adventure novel, and proved very popular in its day.
