Hello.

It sounds like you're describing "Double Whammy" (1987) by Carl Hiaasen

'The "double whammy" is a special lure used in the competitive bass
fishing underlying the plot of this thriller by Miami journalist
Hiaasen ( The Tourist Season ). Someone is cheating at bass fishing
competitions, and people are getting killed.'

" For while the "double whammy" is the lure, first prize is for the
most ingenious murder."

Prompt and correct answer. I had read the book a long time ago and
forgot its title and author. Well done!
