Catch & Keep — Ronald Weber

When ex-newsman Fitzgerald gets a call from a former colleague asking him to track down a missing stringer for a Detroit paper, he follows the reporter's trail to a story of the controversial "catch and release" fishing policy in Michigan's lower peninsula -- and gets quickly hooked by a new murder.

The reporter is dead, shot in the head while she sat at her computer. But she didn't die alone: her husband, rumored to be a local bootlegger, is found dead a few miles away, same execution style. With the help of his girlfriend, Department of Natural Resources agent Mercy Virdon, Fitzgerald picks up the dead's woman's investigation into a group of angry anglers, the Catch and Keep Alliance and their mysterious defenders, a powerful militia group. Soon he's wading into treacherous waters, where a killer is baiting a new hook.
