Detective Inspector St. John Strafford has been summoned to County Wexford to investigate a murder. A parish priest has been found dead in Ballyglass House, the family seat of the aristocratic, secretive Osborne family. The year is 1957 and the Catholic Church rules Ireland with an iron fist. Strafford—flinty, visibly Protestant, and determined to identify the murderer—faces obstruction at every turn, from the heavily accumulating snow to the culture of silence in this tight-knit community. As he delves further, he learns the Osbornes are not at all what they seem. And when his own deputy goes missing, Strafford must work to unravel the ever-expanding mystery before the community’s secrets, like the snowfall itself, threatens to obliterate everything.
