What happens when an alligator crashes a wedding?

Tilly's special day is ruined when not only does a gator make an appearance, but the sound system goes down, it rains, the caterer delivers the wrong meal... and is later found dead.
Some of Tilly's family were the last ones to see the woman alive, and law enforcement believes one of them is the murderer.
As Tilly rifles through the clues to find the real killer, she comes to believe someone sabotaged her wedding on purpose. But are the killer and saboteur the same dangerous person, or does she have two mysteries to solve?
