What is Carton's job and daily working routine? (book 2, Chapter 5)

Carton is a sort of lawyer associate to Stryker.  Although he is brilliant, he is also severely alcoholic, and so serves as a helper, or "jackal", to Stryker rather than as a lawyer on his own.  When Stryker must appear in court, Carton manages to be there too, "with his hands in his pockets, staring at the ceiling of the court", but his primary work is in the evenings, from about 10 p.m. until 3 a.m.when he goes over to Stryker's residence and reads and condenses his legal papers so that Stryker can easily understand them.  He also generally acts as a servant to Stryker, and goes carousing with him when the work is done.
