I was interested by the description of the Cochin Harbour Terminus. Roy described Rahel as an insect, a mosquito, scurrying through the bustle of the crowds. Rahel is subjected to the circus of the underground, malnutrition and children selling the toys that they have the privilege of owning themselves. The twins are described as having "no net to save them as they vaulted through the circus air". Why do you think Roy uses this metaphor on the children? How is it effective?
