"May those who read this book eventually say, closing it: this is the spiritual confession of the last of the executioners!" What will Charles Henri Sanson (1739-1806), the most famous French executioner from the Sanson dynasty, tell us on the pages of his memoirs? What will a man tell us who for four decades carried out death sentences, being present at the last convulsions of his victims - unknown and famous, innocent and those whose hands were "elbow deep"? All of them, these minute acquaintances of his, will pass in a series in front of us along the guillotine to take their last step - a step into eternity.
