Thee Times Lucky by Sheila Turnage

There's something fishy in Tupelo Landing (and it ain't the swamp!).  When Mr. Jesse turns up murdered, Mo LaBeau and her trusty sidekick, Dale Ernhardt Johnson III, are on the case (along with a real detective, not that Mo will let that slow her down.).  The investigation is going along swimmingly until Mo's beloved guardians, Miss Lana, and the Colonel, are kidnapped.  Lucky for Mo, Tupelo Landing has her back!
