Collection of the journalist's articles previously published in varous periodicals. Whether he's reporting on the infiltration of the murderous Aryan Brotherhood into the U.S. prison system, tracking down a con artist in Europe, or riding with a scientist hunting the elusive giant squid, David Grann revels in telling stories that explore the nature of obsession. Each of the stories in this collection reveals a hidden and often dangerous world, pivoting around the gravitational pull of obsession and the captivating personalities of those caught in its grip. There is the world's foremost expert on Sherlock Holmes, found dead in mysterious circumstances; an arson sleuth trying to prove that a man about to be executed is innocent; and sandhogs racing to complete the dangerous job of building New York City's water tunnels before the old system collapses. Throughout, Grann's accounts display the power--and often the willful perversity--of the human spirit, a mosaic of ambition, madness, passion, and folly.--From publisher description.
