On the heels of the success of A Christmas Journey comes this festive mystery. The joyful tranquility of a snowbound estate in the Lake District of England is overturned in a moment by a shocking murder. Renowned mathematician and inventor Henry Rathbone—long known to readers of Perry's bestselling Victorian series featuring William Monk—must put his analytical and creative capacities to the test as he assumes the role of an amateur investigator. In this delightful Christmas tale, he rescues the holiday with a grace that would impress William Monk himself.
