The church in question is St. Lucy's, a humble edifice at the heart of a venerable Chicago neighborhood now suffering the throes of gentrification. St. Lucy's has long stood as a bulwark against evil and change, which some in the community have often seen as much the same thing. Now three dead bodies have been left in the sanctuary, stripped, mutilated, and shot through the head, execution-style. A warning to those who would remake the neighborhood---or to St. Lucy's charismatic monsignor, who has made a few enemies of his own?
