" No, I ran afoul of a law older even than Lankhmar’s and a court less merciful. In short, my friend’s and my own cover was finally blown by the Thieves’ Guild, a most ancient organization with locals in every city of the civilized world with a hidebound law against female membership and with a deep detestation of all freelance pilferers. "

― Fritz Leiber , Swords and Deviltry (Fafhrd and the Gray Mouser #1)
