Murder casts a dark shadow over the christening of Lady Lucy and Major Sir Robert Kurland's daughter Elizabeth—even more so when Lucy's own father, the rector, falls under suspicion for the crime . . .
 
Lucy and Robert’s joy in christening their new daughter, surrounded by extended family and loved ones who have gathered in the village of Kurland St. Mary, is only enhanced when Robert’s aunt Rose—now the second wife of Lucy’s father Ambrose—announces that she is with child. However, not everyone is happy about the news, in particular Rose's adult daughter Henrietta and her husband, who fear for their inheritance.
 
Following the christening, Rose’s disagreeable son-in-law Basil Northam threatens to turn afternoon tea in the rectory into an unsightly brawl. The next morning, he is found in the rector’s study, stabbed through the heart with an antique letter opener, clutching a note that appears to implicate the rector himself.
 
As the local justice of the peace, Robert has an obligation to remain unbiased in his investigation of the ghastly crime, even though his prime suspect is a man of the cloth and his wife’s father. But Lucy is under no such obligation. As snow traps the members of the christening party in Kurland St. Mary, she vows to clear her father’s name and bring the cold-blooded culprit to justice. Someone had better start saying their prayers . . .
