Whoever thought small-town retirement could be this dangerous?

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 reel in the truth. She enlists Paul and his walleye-expert buddy, Ray, to help her get to the bottom of the murky mystery.
