Boston Globe mystery reviewer Winks asked 15 of his favorite authors to sub mit essays on their craft. Four declined and Donald Hamilton entitled his short piece ``Shut Up and Write.'' After reading the other chapters by Robert Barnard, Rex Burns, K. C. Constan tine, Dorothy Salisbury Davis, Michael Gilbert, Joseph Hansen, Tony Hiller man, Reginald Hill, James McClure, and Robert Parker, Hamilton's advice seems very apropos. The essays are un even in quality, length, and focus and shed varying degrees of light on their authors' techniques and philosophies. Of slight interest to inveterate mystery readers and potential writers, this col lection is recommended only for inclu sive university libraries supporting popular culture programs.
