"Home to Roost," by Holly Schofield, in Black Cat Weekly, #195.
I admit to a little bias on this choice. The story would have fit perfectly in the anthology I edited last year, Crimes Against Nature: New Stories of Environmental Villainy. The theme resonates with me.
Kate and Rob are the RCMP constables operating on a small island off the coast of British Columbia, an island suffering from an assortment of environmental crises. They are investigating the death of Bert McCandless, who is an ecological disaster all on his lonesome. He's the sort of guy who would cut down protected trees with a chainsaw - during a period of high wildfire risk.
But now Bert is dead, in a bizarre incident that might be murder, accident, or even suicide. There are plenty of possible clues but can Kate tie them together?
I won't say more except that the story is well-written and cleverly plotted.
