The sparkling letters of a great author are always well worth reading. This is especially true of Charles Dickens who was an incessant traveler, kind friend to many, and a close observer of the social issues of his age. Not to mention often funny.
Here one can glean insights on writing for publication, on forms of thank you and bereavement notes, on career advice, on travel, and on direct but polite ways to say no.
In these letters one often comes across the unexpected line that makes reading a joy. For example, from a letter dated November 5, 1841, "In this kind of work the object is,--not to tell everything, but to select the striking points and beat them into the page with a sledge-hammer."
Those interested in obtaining a biography of Charles Dickens have many excellent options. One from last year, on his early years, that I would recommend is "Becoming Dickens" by Robert Douglas-Fairhurst.
