“A riveting read, Dillon creatively weaves the narratives of her CIA father’s career and family life with those of Dmitri Polyakov, one of the Cold War’s most valuable Russian assets. An untold and important story that’s been a long time coming, this book is worth the wait.” — The Hon. John Lehman, Former Secretary of the Navy and 9/11 Commissioner“This spellbinder spans lives, families and politics on opposite sides of the Cold War, combining suspenseful accounts of two intelligence agents deeply committed to avoiding nuclear war with each family’s unique—and heartbreaking—experiences. This moving story is gripping from start to finish.” — Jacqueline Leo, President and Editor in Chief, The Fiscal Times; former Editor in Chief, Reader’s Digest“A beautifully written, profoundly moving account of one of the most important U.S Intelligence sources ever run inside the Soviet Union. A cliff-hanger from beginning to end, Dillon’s account is filled with espionage tradecraft and family drama—essential reading for anyone fascinated by how spying really works.” — Peter Earnest, Executive Director, International Spy Museum“Interweaving details of daring tradecraft with moving human elements, Dillon tells the fascinating story of two agents and their families with differing experiences and perspectives, and very different outcomes. This mesmerizing book will appeal to historians, spy-buffs, intelligence professionals and everyday readers alike.” — H. Keith Melton, author of Ultimate Spy, and co-author (with Robert Wallace) of Spycraft and the Spy Sites series“Eva Dillon expertly tells an untold chapter of Cold War espionage from a front row seat. It was her father, after all, who was the Spymaster. This is a warm, riveting, great read.” — Joe Drape, New York Times bestselling author, American Pharoah and Our Boys“With detail and technique that are almost novelistic, Dillon weaves the personal stories of the two families: her own and that of Polyakov. Reads like a fine spy novel whose ending we know but whose story transports us nonetheless.” — Kirkus Reviews (starred review)
