The New York Times best-selling final book by the beloved, Pulitzer Prize-winning historian Tony Horwitz.

With Spying on the South, the best-selling author of Confederates in the Attic returns to the South and the Civil War era for an epic adventure on the trail of America's greatest landscape architect.

In the 1850s, the young Frederick Law Olmsted was adrift, a restless farmer and dreamer in search of a mission. He found it during an extraordinary journey, as an undercover correspondent in the South for the up-and-coming New York Times.

For the Connecticut Yankee, pen name "Yeoman", the South was alien, often hostile territory. Yet Olmsted traveled for 14 months, by horseback, steamboat, and stagecoach, seeking dialogue and common ground. His vivid dispatches about the lives and beliefs of Southerners were revelatory for readers of his day, and Yeoman's remarkable trek also reshaped the American landscape, as Olmsted sought to reform his own society by creating democratic spaces for the uplift of all. The result: Central Park and Olmsted's career as America's first and foremost landscape architect.

Tony Horwitz rediscovers Yeoman Olmsted amidst the discord and polarization of our own time. Is America still one country? In search of answers, and his own adventures, Horwitz follows Olmsted's tracks and often his mode of transport (including muleback): through Appalachia, down the Mississippi River, into bayou Louisiana, and across Texas to the contested Mexican borderland. Venturing far off beaten paths, Horwitz uncovers bracing vestiges and strange new mutations of the Cotton Kingdom. Horwitz's intrepid and often hilarious journey through an outsized American landscape is a masterpiece in the tradition of Great Plains, Bad Land, and the author's own classic, Confederates in the Attic.

"A tour is only as good as its guide, and Horwitz is a seasoned one - inquisitive, open-minded, and opting for observation over judgment, whether at a dive bar, monster truck rally, the Creation Museum, or a historical plantation. The book will appeal to fans of travelogue, Civil War-era history, and current events by way of Southern sensibilities." (Booklist)

"With the keen eye and deft pen that he's long brought to telling the odd and wonderful and fascinating story of America, Tony Horwitz has returned to familiar territory - the South - to give us a unique piece of reportage from a region that tells us a whole lot more about the country than the country sometimes wants to admit. Like his classic Confederates in the Attic, this book will be read, remembered, and treasured." (Jon Meacham, Pulitzer-Prize-winning historian and author of The Soul of America)
