Sherlock: Season 4

Sherlock Holmes and Dr. Watson find themselves in 1890s London in this Christmas special.

Sherlock takes on the case of finding out who is going around and smashing six unique head statues of late Prime Minister Margaret Thatcher.

Sherlock goes up against the powerful and seemingly unassailable Culverton Smith - a man with a very dark secret indeed.

A dark secret in the Holmes family rears its head with a vengeance, putting Sherlock and friends through a series of sick, manipulative psychological and potentially fatal games.
