There are three storylines in this chapter. Which characters are being followed?

The structure of this section is an effective dramatic technique. The way Mandisa breaks up the action with alternating segments that start long and progressively get shorter helps build anticipation in the reader. As the time remaining until Amy's murder shortens, so does our time left with the protagonists. Every time we are sent back to Mxolisi and his friends, we hope they are not approaching Amy's car, even as we know they are. By the end of the chapter, we only get glimpses of each, like flashing between scenes in an action movie, or like glimpses through the windows on a train.
