This book is an anthology containing sections named after various authors. All of the authors possessed secret knowledge on how to invent detail that they inserted in their stories. The book was named after Mark Twain because his contributions were significant. Other authors include Robert Louis Stevenson, Sir Arthur Conan Doyle and Agatha Christie. The book focuses on the techniques used to invent ideas from words. These words used to invent new ideas usually involve the names of the characters in the story. On some occasions the author uses his own names to invent ideas which are inserted in the plot of the story. You will notice that the word TWIN can be created from several letters from the name Twain. This idea of twins was used extensively in the story "The Prince And The Pauper".
