James Moriarty. Consulting criminal, psychopath…time lord? After shooting himself on the top of St. Bart’s, Moriarty regenerates and teams up with Sebastian Moran to enact a calculated plot of revenge. Their targets: Sherlock Holmes, John Watson, and, most importantly, the Doctor. Sebastian is used to war zones and sniper rifles, not aliens. But Moriarty is about to drag him into a plot that goes back centuries, and could spell disaster for humanity.
