It's always Carlotta. That name means nothing but trouble :)

A policeman turns up at the isolated home of a writer and his wife telling them an infamous gangster has escaped custody and may be heading their way. They are told particularly because of the relationship the writer had with the criminal in college. We learn that the writer was only able to finish college and become who he was because the criminal robbed a bank for the money he needed for tuition. He accepted the money, and with it, an indebtedness that must, at some time, be repaid.
