7. What is Jerry Cruncher’s secret nighttime activity? What theme from the does this activity reinforce?

Jerry Cruncher's secret nighttime activity is grave robbing. Cruncher is nicknamed the "resurrection man". He literally sells the dead to science thus resurrecting them from the grave for a new purpose. We see imprisonment as a type of death throughout the novel with the few lucky getting to leave prison and start a new life. Even leaving prison dead becomes a resurrection of sorts. There is also the theme of the double life. Jerry passes for respectability but at night he robs graves. Similarly you might consider a character like Charles Darnay who only wants to be ordinary yet is actually the heir of the aristocratic Evremondes.. .
