Death of a Hoosier Schoolmaster

Language arts teacher Margo Brown, who tracked down the killer of one of her students in Why Johnny Died, finds herself drawn into amateur sleuthing again in Marlis Day's Death of a Hoosier Schoolmaster, this time because she discovers an old gun buried in her garden. Believing it was used to kill the titular fellow some five decades earlier, Margo and her pal Roxie set out to find the truth behind the unsolved murder but it quickly becomes clear that the case has present-day significance.
