Sir William Blackstone 
Commentaries on the Laws of England [EPUB ebook] 
Book III: On Private Wrongs

The Commentaries were long regarded as the leading work on the development of English law and played a role in the development of the American legal system. They were in fact the first methodical treatise on the common law suitable for a lay readership since at least the Middle Ages. This is book three out of four, including more than 1900 footnotes and annotations.
