A Gentleman Under the Mistletoe — Grace Burrowes

Lord Julian Caldicott is standing in for his ducal brother as manager of Yuletide merriment at the family seat. Alas for his lordship, nothing is going as planned. Cranky relatives arrive uninvited, family squabbles ensue, and Julian's annual case of the blue devils is worsening by the day.

Julian decides to combat the mayhem and melancholia by anonymously spreading good cheer. He arranges a series of discreet gifts--for the village church, for his nephew, for Caldicott Hall's retired housekeeper, and others--but every time he attempts to play secret Father Christmas, an unknown benefactor upstages him with gifts of equal generosity. Who is Julian's competitor for top elf honors and why are they determined to make this Julian's worst Christmas ever? Julian vows to find out!
