Hello everyone! I would like to know what "a life of public mischief" means in the following sentences. "There was a change in both of us. We had lost the sense of discovery which had infused the anarchy of our first year. I began to settle down. Unexpectedly, I missed my cousin Jasper, who had got his first in Greats and was now cumbrously setting about a life of public mischief in London; I needed him to shock; without that massive presence the college seemed to lack solidity; it no longer provoked and gave point to outrage as it had done in the summer." This is an excerpt from Brideshead Revisited by Evelyn Waugh. At the beginning of the summer semester at Oxford, Charles' cousin Jasper, an important person in the university, came to his rooms to give some advice on various aspects of college life, which Charles found nosy; nevertheless, when the fall semester began, he unexpectedly started to miss his presence. Here, I could not understand what is a life of public mischef. I heard that there is actually a crime named "public mischief," but I couldn't be sure whether the underlined part really indicated that. I would very much appreciate your help.
