Dark, power-hungry wizards....
But this time, it is different.
It is personal.

he finds a mystery growing around his own friends.
One by one they are mysteriously vanishing.
Taken by an invisible force, which can strike unexpectedly.
Holmes's loved ones are vanishing without a trace.

Or is Christmas going to be desolate and empty for him?
