In Murder Mayhem, Dr. Doug Lyle culls the best of his popular 'The Doctor is In' QA column for the Mystery Writers of America, in which he answers medical and forensic questions from writers all over the country. Clearly organized into subjects such as 'Weapons of Death,' 'Police the Crime Scene,' 'the Coroner the Crime Lab,' and more, the questions cover a wide range: Do pupils shrink or enlarge with death? Can ingested cocaine kill? How soon do strangu-lation bruises appear? Lively and accessible, this solid reference is bound for every mystery writer's shelf.
