This had been the third morning in succession, on which there had been early drinking at the wine-shop of Monsieur Defarge. It had begun on Monday, and here was Wednesday come. There had been more of early brooding than drinking; for, many men had listened and whispered and slunk about there from the time of the opening of the door, who could not have laid a piece of money on the counter to save their souls.
