Frances and George are looking forward to a Christmas season enlivened by all the diversions London can provide. But family comes first, and George’s sister Fiona and her husband persuade everyone to gather at their Norfolk estate for the holiday. The weather will be chilly, but the prospect of snow delights the youngsters. And with blazing fires and invigorating country walks in store, Frances envisions a peaceful, jolly Christmas.

Instead of a picturesque snowfall, however, Norfolk is hit by pounding rainfall and high winds. In the aftermath of the storm, Frances, Fiona, and the children make an unpleasant discovery in a nearby field—the body of their neighbor, dead in suspicious circumstances. Joshua Penhollow was the local coroner and doctor, though not a well-respected one. Indeed, most viewed him as a quack, and even his own stepdaughter held a grudge against him.

With the police and the menfolk gone to help clear a blocked road and the coroner dead, the investigation falls to Frances and Fiona, who must also curb the young people’s excitement at encountering a real-life murder. Combing through a village full of colorful characters and more than a few suspects, Frances feels any hope of a quiet Christmas slipping away. But more pressing is the need to stop a killer whose heart is as cold as the season.
