I Shall Not Want by Julia Spencer-Fleming
Clare Ferguson is an Episcopal priest and former army pilot. Russ Van Alstyne is chief of police of Millers Kill, New York, whose wife was recently killed. In this sixth mystery featuring the duo, a Mexican farmhand stumbles across a body on the dairy farm where he works. Two more bodies are discovered--all victims are young Latino males. Hate crime or part of gang-related drug activity?
Clare and Russ are attracted to each other but both feel guilty because of the death of Russ's wife. The author has won numerous awards including the Anthony, Agatha, and Nero Wolfe awards.
