Calamity Jayne (Calamity Jayne Mystery, #1) by Kathleen Bacus

Tressa Jayne Turner has had it up to here with the never-ending string of dumb-blonde jokes and her longtime nickname. Crowned "Calamity Jayne" by Iowa Department of Natural Resources officer Rick Townsend, Tressa's out to gain a little hometown respect --or die trying. Unfortunately for Tressa, that may be the case. She's just been handed the perfect opportunity to get "Ranger Rick," the doubting Don Juan of the DNR, and a skeptical citizenry to finally take her seriously. How? By solving a murder no one else believes happened...No one, that is, except the killer.

Yup, Calamity Jayne is in it up to her hot pink snakeskin cowgirl boots and matching rhinestone belt. Tressa would tell you her momma never raised no dummies, but the jury's still out on that one.
