After a rough semester, Professor Lyssa Pennington just wants to post her grades and join her husband, Kyle, in Cornwall for Christmas.

And, by the way, Emile Duval is an imposter. Who is he really? And who wanted him dead? Without those answers, the Penningtons can kiss Christmas in Cornwall goodbye.
