Showing Dead Angler by Victoria Houston

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. Whoever thought small-town retirement could be this dangerous?
