Which author wrote three books, each containing the word beau in title?

The titles of the three books are Beau Geste, Beau Sabreur and Beau Ideal and they were written by Percival Christopher Wren who was born in 1885. Having served in the British, French and Indian armies and having been a member of the French Foreign Legion, he was for a while assistant director of public education in the Bombay Presidency.

His dramatic and action-packed novels of life in the Foreign Legion won him immense popularity as an author. The Wages of Virtue, published in 1916, was the first. Beau Geste came along in 1924 and it is for this book that he is world-renowned. Beau Sabreur in 1926, Beau Ideal in 1928 and Flawed Blades in 1933 were the rest of his Foreign Legion novels. He wrote other books but not one achieved the same success as those with a Foreign Legion background. Beau Geste has been filmed by Hollywood onat least three occasions. It has also appeared as a television serial. PC Wren died November 23, 1941.
