the Letter Shocked and angry Dr Manette father of Lucie Manette wrote a detailed letter to the authorities He included the whole truth about the crime He exposed the brothers cruelty and injustice But before he could deliver it the Evr mondes found out They kidnapped him and locked him in prison to keep him silent While in prison he hid the letter in his cell wall The Letter s Effect Years later during Charles Darnay s trial in Paris Madame Defarge found the hidden letter Her husband Monsieur Defarge reads the letter in court during Charles Darnay s trial The revolutionaries used it as proof against Darnay They were saying he was guilty because he was part of the Evr monde family Even though Darnay had no part in the crime the court sentenced him to death by guillotine the next day In short Dr Manette s letter was an honest cry for justice But it became the reason for his son-in-law s death sentence
