In chapter 11, how does Tom's conscience affect him after the murder? Give evidence from the text with a quote.

In the days following, Sidney begins to notice a change of behavior in his brother. Tom tosses in his sleep, keeping Sid awake with his nightmares. At school, Sid notices that Tom seemed to lose interest in all schoolyard activity, including the dissection of dead cats. Instead of playing with the other children, Tom would sneak away from the schoolyard to the jail cell where Muff Potter was held prisoner, smuggling small tokens and gifts through the barred cell window ­ an outlet to ease Tom's guilty conscience.
