Under the Andes was written by Rex Stout years before his creation of the immensely popular Nero Wolfe series of novels, and while perhaps his future writing style is still blossoming, certainly his knack for weaving a fantastic tale of mystery and adventure will have most readers anxious for the next phase of adventure at every turn. The story finds two brothers and a pretty female companion on a journey which eventually takes them to a series of underground caves under the Andes of South America, where they encounter a lost tribe of Incas who have apparently survived hundreds of years oblivious of the outside world...

From celebrated crime author Rex Stout, creator of the long-running Nero Wolfe detective stories, comes this early mystery, that served as an inspiration to the first Nero Wolfe novel Fer-de-Lance, of a golfer who, while out on the greens, clutches his chest and keels over from an apparent heart attack. But the coroner rules it a poisoning, and the president of the country club, Canby Rankin, takes it upon himself to track down the killer. - Summary by Ben Tucker
