Set after the Great War, Reverend Hawthorn, clergyman to a small parish, is horrified when multiple members are slaughtered around the full moon. But to disclose that the Church cannot protect its member proves an obstacle. Without options, he enlists the services of Roland Marshall, a former soldier and recent monster hunter, paying him handsomely to hunt down and mount the unholy beast on his wall. Still, problems later arise after he and Joseph Dunham, constable to the parish, find a den hidden beneath the Church, leaving Roland Marshall to wonder whether payment will be enough for the bloodbath to come.
