Greg Herren's Who Dat Whodunnit takes place during the period between the Saints beating the Vikings for the Conference Championship and the Super Bowl where they kicked the crap out of the Colts. surprising everyone. In order to get us into this mindset of all of Louisiana running around yelling "Who Dat!" and "Geaux Saints!" like Cajun Cincinnati-ans... (As someone who grew up listening to crazy Southern Ohioans scream "Who Dey!" for the inferior Ohio team...)
Anyway, to tie us into the absolute insanity that happens when a city's much maligned team suddenly does well, we meet Scotty's cousin Jared, who warms the bench for the Saints, and is therefor the apple of Papa Bradley's eye. Jared just happens to be sort of dating Tara Bourgeoisie, who happens to be a more modern and plastic surgeried Anita Bryant, rallying Louisiana to kill the gays.
Well, Tara winds up dead, shot with Scotty's mom's gun. (It seems pacifism ends when the levees break and one has to defend what's left of one's property.) And the Marina Werner, daughter of the pastor hosting the anti gay rally Tara was supposed to speak at ends up dead, also killed with Mom's gun. Jared ends up hiring Scotty and Colin (Frank is wrestling for a World Title in the regional even team he's part of) to clear everyone in the family, since he found Tara's body and really doesn't have much of an alibi.
Which of course leads into turning over several rocks from everyone's past, including the Bradley family, as a bunch of stinky laundry gets aired out.
While it's a good yarn, and very engaging, I can't help but notice most of the series is set up like Murder, She Wrote, where we get introduced to a family member or family friend who either gets murdered or becomes the prime suspect.
