Showing Dead in the Water by Dana Stabenow

Two crewmen of the crab vessel Avilda are missing—presumed dead—under very suspicious circumstances. The Bering Sea offers ample means and opportunity, but without bodies, a motive, or evidence of foul play, the DA doesn’t have a case. And so, freelancing again for her former employer, Kate Shugak finds herself working undercover in one of Alaska’s most dangerous professions: crab fisherman. It’s an assignment that will take her from the debauchery of Dutch Harbor to the most isolated of the Aleutians, and if the job itself doesn’t kill her, her unsavory crewmates just might.

Third in Stabenow’s Edgar Award-winning series of Alaskan mysteries, Dead in the Water is richly informed by the author’s own upbringing aboard an Alaskan fishing vessel.
