Percival Christopher Wren (1875–1941) was a prolific author of adventure fiction whose novels and short stories chiefly tell of colonial soldiering in Africa. He served as headmaster at India's Karachi High School for two decades, after which he is reputed to have joined the French Foreign Legion. Although the proof of his military service is inconclusive, Wren's fictional accounts of life among the legionnaires are noted for the accuracy of their details.
