The scapegoat - Daniel Pennac

Pathetic, contrite and hapless, Benjamin is nonetheless the scapegoat at The Store: there is nothing for which he cannot be blamed. While his blunders remain minor, most of his unwitting victims can find it in their hearts to forgive him, but when violent explosions begin to follow him around, he inevitably becomes the prime suspect. With his girlfriend Julie by his side, Benjamin thrusts himself into uncovering the mystery, delving deep into underground Paris and pursuing the truth through a maze of bizarre criminality and oppressive shadows.
