This book tells the true story of such a group of people. They are mysterious, unknown, and pervasive. Their victory cannot be publicized, without flowers or applause, and their failure is silent, without any opportunity for explanation. As soon as they stepped into the world of espionage, they were separated from normal life; they worked, worked, and worked again, but they could not control their future. As the French spy master Leroy said when looking back on his 30 years of espionage work: "I was determined to devote myself wholeheartedly to the spy career, even at the expense of my own life. I worked in my own unique way. In order to obtain intelligence, I searched everywhere and always succeeded. But I never expected that what was waiting for me at the end of the road would be a tragedy." As long as you open this book, you will feel like you are there and you can truly understand it.
