Sherlock Holmes and Joan Watson come into contact with MI-6, the British intelligence agency, when a run-of-the-mill murder investigation turns out to have international and political implications. Meanwhile, in the wake of a crisis, Watson re-evaluates her relationships with Sherlock and his brother, Mycroft.
- Jonny Lee Miller – Sherlock Holmes
- Lucy Liu – Joan Watson
- Aidan Quinn – Captain Thomas Gregson
- Jon Michael Hill – Detective Marcus Bell
- The title of this episode comes from Sherlock's observation, about himself and Mycroft, in "The Adventure of the Greek Interpreter", that "Art in the blood is liable to take the strangest forms." It is in reference to their grandmother having been the sister of "Vernet, the French artist", though whether this is Claude Joseph, his son (whose sister died on the guillotine during the French Revolution) or grandson is not specified.
- Sherlock said in the final scene of the first episode of this season, "Art in the blood, Watson. It takes the strangest forms." This may have been a foreshadowing.
