Retired dentist Paul Osborne hasn’t fly fished since his wife died. He hasn’t had a woman tell him what to do since then either. But in the company of Lewellyn Ferris, he’s relearning both. And when he and his lady instructor find a well-dressed body floating in the moonlight, Paul adds deputy to his list of experiences...

Whether the death is accidental -- or accidentally on purpose -- Lewellyn is determined to rell in the truth. She enlists Pail and his walleye-expert buddy, Ray, to help her get to the bottom of the murky mystery. Whoever thought small-town retirement could be this dangerous?
