Secret Listeners, The

This fascinating book tells the story of the Y Service, England's unit of radio operators who operated secret radio-listening stations in England and around the world during World War II. They listened to enemy radio transmissions and transcribed them. Some of the transcripts were decrypted and analyzed locally. Some were sent to the code breakers back at Bletchley Park. The information gleaned from these transcripts was shared with military commanders, who used it for tactical advantage. The information for this book was gleaned from interviews with Y Service operators, their memoirs and letters, and declassified government documents. Owing to its abundance of reminiscences of Y Service operators, this book has a compelling "boots on the ground" vibe. By the way, the "Y" in Y Service is from "W.I.," the initials for "Wireless Interception." This is a well written book, and the audio book version is well narrated. Highly recommended.
