New Orleans criminal psychologist Kit Franklyn, lately drowning in personal doubts about her life and career, thinks that investigating the corpse she found in the garden of her new home will be the perfect distraction. Together with her boss, chief medical examiner Andy Broussard, she sets out to solve this case that seems plain unsolvable. Though they identify the body as a missing hooker, now dead 27 years, all hope of conviction still seems lost.
Like bananas, Sheriff Cas Larkin's troubles are ripening in bunches. A fully dressed woman is found drowned in the lake. He has a citizen no one can find, but hasn't been reported as missing and all of her known acquaintances are standing in the way of Cas's investigation. Then Judge Carpenter's fiancée lands in jail, accused of a bloody murder way down yonder in New Orleans! Now Cas must pick up the pace and connect the dots... before he goes bananas himself.
