“In ‘The Determined Spy,’ Douglas Waller…gives detailed and nuanced treatment to both Wisner’s outsize role in the early CIA and his disease, leaving judgment to the reader…It’s a rich history, mostly drawn from recently declassified CIA records that cover everything from bureaucratic wrangling to foreign policy debates at the highest level.”
—The Washington Post

“The biggest surprise in Waller’s lively biography of Frank Wisner…is how stunningly naïve U.S. covert and martial operations have been at times. As Waller shows, Wisner’s tenure provides one of the harsher lessons of the world of espionage: What appears to be a success at the time may not prove so over the long run.”    
—The New York Times

“Was the earlier, swashbuckling CIA a more successful enterprise than its present, decidedly less picturesque incarnation? In ‘The Determined Spy’ Douglas Waller, a historian and journalist, investigates that question by chronicling, in considerable detail, the ‘turbulent’ life of Frank Gardiner Wisner.”
—The Wall Street Journal

“Waller offers us a picture of a postwar America that felt it had the power, and the right, to craft the rest of the world to its liking.”    
—The Nation

“In this fascinating and deeply researched biography of the CIA bigwig Frank Wisner, Douglas Waller uncovers a trove of mid-century secrets that help explain the world we’re living in today, and how a man who most people have never known about shaped it. Devour the book and then join us in daydreaming about casting the inevitable biopic.”    
—Town & Country

“A revealing look at the early history of a spy agency with a decidedly checkered past.” 
—Kirkus

“In this sweeping, immersive, and full-bodied study, journalist Waller, who authored a 2011 biography of OSS founder Wild Bill Donovan, turns to another central figure in American spycraft, Frank Wisner.” 
—Booklist (Starred Review)

“This book is an excellent biographical history for anyone interested in Cold War history and the CIA’s formative years and those who appreciate the complexities of espionage and its human cost. VERDICT: With its richly detailed historical context, this biography will entertain readers seeking a deeper understanding of the Cold War era.”  
—Library Journal 

 “Douglas Waller’s ‘The Determined Spy’ is not only an excellent history of the early CIA’s covert action operations but also a human drama of a central figure in that history plagued by a crippling mental disorder… The comprehensive biography of Wisner and history of the OSS and early CIA covert action are woven into a compelling narrative, richly supported by Waller’s exhaustive research and spiced with anecdotes from a wealth of sources.”  
—Cipher Brief (Four Trench Coats)

“’The Determined Spy’ is a serious book, a study of American covert power and its lasting effects on those who attempted to wield it, as well as on the world at large.”  
—The Guardian

“An illuminating, action-packed account that chronicles multiple CIA adventures—and misadventures…Waller has masterly invoked the sense of the apocalyptic doom and gloom that drove the Cold War in both Moscow and Washington and was the menacing backdrop to all of Wisner’s operations.”  
—SpyTalk

“Unknown to the public, Frank Wisner was one of the most powerful men in the world during the early days of the Cold War. He ran covert actions for the CIA when the spy agency was at the peak of its ambition. That Wisner ended up in a mental hospital and later killed himself was a fascinating and profound tragedy. A thorough and fair-minded historian, Doug Waller reveals the whole story, in gripping detail, and he tells it brilliantly.” 
—Evan Thomas, New York Times bestselling author of The Very Best Men and The Road to Surrender

“In The Determined Spy, Douglas Waller does an admirable job of piecing together long hidden and very forbidden secrets, among them development of the notorious MKUltra mind-bending drugs intended to create human robots. For more than a decade, during the coldest days of the spy war with Moscow, Frank Wisner ran the CIA’s most secret department as deputy director of plans. For spy-readers, Waller’s new book is a wonderful follow-on to his earlier book on the founder of the OSS, Wild Bill Donovan.” 
—James Bamford, national bestselling author of The Puzzle Palace, Body of Secrets, and SpyFail.

“Secret agents, soaring ideals, coup plots and intelligence disasters — all of it runs through Douglas Waller’s remarkable biography of CIA pioneer Frank Wisner. This is a tale of a shadow warrior at the dawn of the Cold War who fervently fought for freedom then tragically succumbed to personal demons.” 
—David E. Hoffman, national bestselling author of The Billion Dollar Spy

“Thanks to an illustrious career of tracking the intelligence world, there are few who write about the CIA with as much authority as Douglas Waller and as much understanding of the human beings involved. In The Determined Spy, he deftly lays out the challenges, the compromises and the controversies of the CIA, but also the heavy personal cost to one of its early and most powerful leaders, Frank Wisner. With sensitivity but also admirable rigor, Waller reveals the story of a flawed man who fought the Cold War in the shadows with everything he had but was consumed by his own demons. A must for students of spying.”
—Sonia Purnell, author of Kingmaker: Pamela Harriman’s Astonishing Life of Power, Seduction, and Intrigue
