Arthur Conan Doyle, 1892. 12 chapters in 791 pages of about 125 words.
Twelve stories of Sherlock Holmes and Dr. Watson, first published in The Strand Magazine and collected in 1892: A Scandal in Bohemia, The Red-Headed League, The Speckled Band and nine more. Each case is complete in itself, so you can type one story at a time.
Conan Doyle wrote quick, precise dialogue, with names, numbers and amounts of money along the way, which makes the stories good practice for the keys plain word tests leave out.
