Birdsong

Lannister had shot Commissioner Aerys Targaryen in the back, the most corrupt policeman of them all, back when Jaime too had worn a shiny badge on his jacket. Jaime’s bullet had ended the police’s reign, and ever since, the wealthy, influential families had struggled for the rule of the city. Some, like Petyr and Varys, made a fortune in all the chaos, others, like the Starks, were less lucky.
The state’s law had been a joke even before Aerys’s death, and now it was nothing but a half-forgotten story.
The mafia made its own rules.

And Sansa Stark had been a pawn in all their plays right from the start.
