Someone took her bag. Reached down and took it from her with an ease, a confidence, that suggested he was meant to take it, that he was a functionary performing an accustomed task, like the young women bowing welcome at the doors of Tokyo department stores.

Kicked him in the back of the knee, pivoting smoothly, like the Thai boxing girls in Swain's billiard room, snatching the bag before the back of his skull and the stained concrete met with an audible crack.
