"Disciples is a fantastic book, one of the very finest accounts of wartime spookery I’ve seen. . . . it’s a hell of a good tale, aided immeasurably by Mr. Waller’s skill at disentangling the knotted story lines of his protagonists and his dexterous straightening of the often contradictory accounts of the shadow war’s dauntingly complex machinations. . . . his eye for journalistic color (honed by his stints as a correspondent for Time and Newsweek) turns his solid research into taut narrative. . . . Disciples is a remarkable work of synthesis."

– The Wall Street Journal

“Entertaining and richly detailed . . . a textured adventure story that emerges from Waller’s command of the archival material and his fluid writing style. That latter gift helps Waller overcome what could have been the cumbersome task of weaving together four distinct war experiences . . . Waller moves among these biographies with ease.”

– The Washington Post

“Entertaining and enlightening . . . absorbing . . . [Waller’s] story of Dulles’ tortuous dance with a German informant while running the OSS activities in Switzerland is worthy of John le Carré. His tales of Colby’s paramilitary operations in France and Norway include riveting episodes of heroism (and a possible war crime that got lost in the Allied victory) that would fit in the best war novels. . . . [Waller] makes the case that these four men’s wartime actions deeply colored what they did as CIA directors. Their zeal in fighting the Nazis, and their acquired love of intrigue, escalated during the battle against communism. Ardor became audacity. And each fell from grace. It’s a messy business.”

– The Charlotte Observer

“Waller has clearly mastered the material and tells each man’s story with verve and energy. Based on extensive research in original sources, which he lays out in endnotes, the chapters are literal page-turners.”

– Studies in Intelligence

“Eye-opening . . . Waller keeps the interest high and the pages turning in one of the more interesting spy books this year.”

– Kirkus Reviews

“Meticulously researched...Waller’s easygoing writing style and extensive use of primary sources make this work worthwhile for those interested in espionage history.”

– Publishers Weekly

“Douglas Waller knows the world of spies and he knows how to tell a story. The World War II adventures of these future spymasters are fascinating and instructive about the moral ambiguities of espionage and covert action. A gripping read from the pen of a master.”

– Evan Thomas author of "Being Nixon" and "Ike’s Bluff"

“Waller reintroduces us to the legendary spymasters who fought in World War II. In his gripping book, Waller gives us the little known backstories of the future intelligence chiefs and their cunning use of espionage and sabotage. Decades later, accused of bungled operations, crimes, and abuse of power, they would all go to war again, but this time just across the river in Washington.”

– James Bamford, author of The Shadow Factory

“Allen Dulles, Bill Casey, Bill Colby and Richard Helms became symbols of the CIA’s worst Cold War failures and scandals. Waller vividly chronicles their accomplishments as young OSS operatives who put their lives at risk during World War II. This is an enthralling story of patriotism, courage, dedication, and at times reckless panache. Given the trajectory of their postwar lives, it is also a tragedy—a true American tragedy.”

– Andrew Nagorski, author of Hitlerland and the forthcoming The Nazi Hunters

“Meticulously researched . . . Waller’s easygoing writing style and extensive use of primary sources make this work worthwhile for those interested in espionage history.”

– Publishers Weekly

“Douglas Waller follows up his best-seller Wild Bill Donovan . . . with a ripping WWII sequel, Disciples . . . . Waller . . . drops a discerning dime on a series of backstories of espionage and sabotage provoked by Donovan’s ‘disciples’. . . Allen Dulles, Richard Helms, William Colby and William Casey, [who] later became CIA directors.”

– The Buffalo News

“This book will make a dandy holiday gift for the spy story buff who eats up yarns about the dark side of the world of intelligence and those masters of intrigue who exist inside the web. This is an authoritatively researched and smoothly written tale. . . Disciples will make good reading for your favorite spy buff.”

– The Washington Times

"Waller’s Disciples offers the reader a thoroughly researched and highly detailed history of these influential spies who ignited the covert action industry of the late twentieth century."

– Military Review

“Disciples is a lengthy but marvelous work—assiduously researched and richly written—that actually delivers on its subtitle.”

– International Journal of Intelligence and CounterIntelligence
