For bookseller and amateur sleuth Claire Malloy getting a root canal beats going to a Malloy family reunion. But it is time her fifteen-year-old daughter Caron visits her deceased father's relatives. Now Claire and Caron have arrived at Malloy Manor, a run-down mansion in Louisiana's bayou country...where the mosquitoes are big enough to barbecue, the swamp is crawling with alligators, the butler looks like he stepped out of a teen slasher movie, and the wheelchair-bound matriarch, Miss Justicia, races around the grounds cackling like a loon.

It's the perfect setting-for a murder. Before a night has passed, Miss Justicia is sleeping with the fishes. The police call it a "tragic accident." Caron is all for calling a cab. But Claire wants to have a closer look at her "loving" relatives since she has a hunch leaving Malloy Manor isn't going to be all that easy...and neither is staying alive.
