Writer's retreat Windy Corner becomes a sanctuary of a different kind when a man and his foster daughter are harassed by a social worker, with tragic consequences.

Emily and Luke Richards are back from their honeymoon and plunged into a whirlwind of activity. Emily's half-brother, Oscar, and his fiancee want to be married at St. Bede's Church with a reception at Windy Corner. But they're not the only guests arriving at Emily's home.

Emily unexpectedly finds herself playing host to the family of the artist repairing the church's stained-glass window, as well as Moses Valory and his young ward, Charlotte, who are seeking sanctuary from social worker Janine Vertue's harassment.

When Janine appears at Emily's door and is later discovered hanged in her hotel room, it becomes apparent that Moses and Charlotte are not the only people in the house with reason to hate her. Could one of the guests Emily and Luke have come to trust turn out to be a murderer?
