Title: The Key to Sixteen - Patrick Raynal - book
Summary :
"Louis Seize... Already, that's a name for a cop! You lose your mind easily... Or, at least, when you lose your illusions, you systematically do the opposite of what we want you to do. For example, an armed robbery. Then you get five years. Firm. And in prison, you learn to be smart, failing to return to the straight and narrow, which, outside, is rather tortuous, crosses Nice, a city where everything is recovered, everything is digested, everything changes, where yesterday's honest people become tomorrow's rotten ones, where those who give lessons never remember the lessons they have given. So you, Louis Seize, head first, you get yourself a scaffold."
