This guide to interactive library programming gives detailed plans and scripts for hosting library events and activities structured as 'mysteries.' The book contains scripts for mysteries, most hosted at Saint Mary's College, as well as instructions and tips for staging a successful mystery event. Events for kids, college students, and adult patrons can be easily adapted to a particular academic, public, or school library, and incorporate features such as puzzles, word games, clues requiring detection and deduction, and historical and book characters (portrayed by library staff). Complete instructions are given for program planning, from writing clues to organizing the event. B&w photos and checklists for preparation are included. The author is affiliated with Cushwa-Leighton Library at Saint Mary's College. Annotation ©2009 Book News, Inc., Portland, OR (booknews.com)
