Exercises in Style retells this apparently unremarkable tale ninety-nine times, employing a variety of styles, ranging from sonnet to cockney to mathematical formula. Too funny to be merely a pedantic thesis, this virtuoso set of themes and variations is a linguistic rustremover, a guide to literary forms and a demonstration of imagery and inventiveness.
