“The Efficiency Expert“ is a novel by Edgar Rice Burroughs, an American fiction writer, who created such great characters as Tarzan and John Carter of Mars.

One of a small number of Burroughs' novels set in contemporary America as opposed to a fantasy universe, The Efficiency Expert follows the adventures of Jimmy Torrance as he attempts to make a career for himself in 1921 Chicago. The book is remarkable for the criminal livelihoods of the hero's friends. It was also admitted to be a fictionalization of Burroughs' own difficulties in finding a job prior to becoming a best-selling writer.
