A detailed study of the essentials of Clemens' literary development that, on many counts takes issue with previous biographers and critics. The forces that made him write, how he wrote the books and why he wrote them as he did, and when, and where, are the questions investigated, substantiated, with refutations when the point seems arguable. Again Clemens' life is detailed, his experiences throughout the country, abroad, that was woven into his writings; his marriage, more opposition to other books here, and the events and accomplishments of his career, until death. A controversial literary figure, understandingly, charitably presented.
