This 'Study Data Annex' presents an overview of the scene, chapter, Act, and character flow of Dennis Lehane's Mystic River. As such, it may be of interest to fiction writing practitioners, and literary critics, as well as academics. It can be seen as a case Study of a masterpiece in contemporary fiction and cinema. Writers can compare their manuscript to the structure of Lehane's work and answer relevant questions. For example, are the manuscript's sentences in general too long or short; are the paragraphs too long; are the scenes varied in length and verbosity; what is the appropriate intensity appearance of a central character; and do the minor characters provide sufficient relief to the central characters?

This annex is, then, merely a compilation of frequency data with respect to verbosity (paragraphs, sentences, words) and ratios (sentences/ paragraph, words/paragraph, words/sentence), and scene character appearance. The overview is given in a long, scene by scene, diagram, color coded for character reference density (primary and secondary), and verbosity (overall and paragraph). The data is also reviewed in graphical format. A table of Microsoft generated (not entirely accurate for styling reasons), data is also provided, along with standardized results, for easier scene comparison. In addition, the major diagram, and supplemental graphics, are preceded by brief discussion remarks, providing guidance from Lehane's techniques of construction. Two scenes are also examined at the functional grammatical level., and at the level of scene story analysis. The annex then provides a foundation for further self-study of Lehane's construction and plotting.
