Mischief in Maggody by Joan Hess

When a woman is shot in a cannabis patch, Arly Hanks must restore order to her Ozarks community, in this sharp-witted mystery by an Agatha Award-winning author.
When small-town police chief Arly Hanks returns to Maggody, Arkansas, after vacation, she finds the population has risen to a booming 802. Among the newbies: Madame Celeste, the psychic who's holding locals in thrall with her predictions of doom; a handsome new high school guidance counselor; and a gaggle of mantra-chanting hippies who have turned the old general store into the source for cosmic harmony. Unfortunately, life in Maggody is anything but harmonious.
Robin Buchanon-a member of Maggody's most abundant family-has been murdered. The moonshiner, prostitute, and mother of four foul-mouthed little bad seeds was found shot to death in a booby-trapped marijuana field. Assuming the weed harvesters are sending a message to trespassers, Arly decides to hold vigil and set her own trap. But when another, seemingly unrelated, murder catches Arly off-guard, even Madame Celeste can't predict where this case is headed.
An Agatha Award finalist, Mischief in Maggody is just the kind of "bawdy, cheerful entertainment" that has brought countless fans to Joan Hess's quirky, long-running Maggody series ( Kirkus Reviews).
Mischief in Maggody is the 2nd book in the Arly Hanks Mysteries, but you may enjoy reading the series in any order.
