In the Bleak Midwinter by Julia Spencer-Fleming

In the Bleak Midwinter introduces Episcopalian priest Clare Fergusson and Russ Van Alstyne as a mystery-solving team based in Millers Kill, a small town in upstate New York. Clare is a former Army chopper pilot, taking her first posting after seminary. Russ is police chief, and also a former military man. They are brought together when a baby is left on the steps of the Episcopal church. Within a couple of days, the baby's mother is found dead--murdered by a blow to the head, followed by exposure to the winter cold. As the bodies pile up, the mystery grows, as does the attraction between Clare and Russ.

These are engaging characters, and the mystery is well plotted. In the Bleak Midwinter is a highly enjoyable first mystery, and the start of an interesting series.
