Mundy, Talbot: The Ivory Trail. V1. 23 Feb 2010
 

Talbot Mundy (born William Lancaster Gribbon) (April 23, 1879 – August 5, 1940) was an English writer. He also wrote under the pseudonym Walter Galt. Born in London, at age 16 he ran away from home and began an odyssey in India, Africa, and other parts of the Near and Far East. By age 29, he had begun using the name Talbot Mundy, and a year later arrived in the United States, starting his writing career in 1911. His first published work was the short story "Pig-Sticking in India", which describes a popular, though now outlawed, sport practiced by British forces.

Excerpt
Estimates of ease and affluence vary with the point of view. While his older brother lived, Monty had continued in his element, a cavalry officer, his combined income and pay ample for all that the Bombay side of India might require of an English gentleman. They say that a finer polo player, a steadier shot on foot at a tiger, or a bolder squadron leader never lived.

The topic is Ivory Trail, but the book is Winds of the World. Same in all four topics for this book.
