S04E23 The Invisible Hand
Crime, Drama, Mistério
The invisible organisation behind all the recent troubles for Morland Holmes does indeed turn out to be the group created by Jamie Moriarty. Command of the group, which was falling into chaos, was handed over to her former lover and father of her child, a brilliant university lecturer who was the true love of her life, (perhaps). Holmes and Watson have to somehow connect all the crimes perpetrated by Krasnov on his employer, the enigmatic, 'Invisible Hand'.
