The Lying Detective



Critic Consensus: "The Lying Detective" is a return to true Sherlock form -- with a strong mystery for its two leads to solve, and the enticing introduction of a new villain.

Episode Info

Sherlock faces perhaps the most chilling enemy of his long career: the powerful and seemingly unassailable Culverton Smith - a man with a very dark secret indeed. Estranged from his best friend John Watson, Sherlock seems to have descended into hell. Is there any way back from the abyss into which the detective has fallen?

Critic Reviews for The Lying Detective

Sherlock continues to be a class act - a testament to the almost hallucinatory talents of creators Mark Gatiss and Steven Moffat, and proof of the malleable potential of Arthur Conan Doyle's pipe-smoking detective.

Sherlock is back in fine form with a Moffat-penned episode that gives us plenty of mystery and a genuinely scary villain.

Well, this was a mind-trip. Sherlock Season 4 Episode 2 made my head spin, and I loved it. The uncertainties, twists and turns made for a packed and intriguing episode.

Though "The Lying Detective" may be built on a house-of-cards logic, it's still a pretty house. We're left with much groundwork to be done for next week's season finale, and plenty of questions.

It all adds up to "The Lying Detective" being a mixed bag of entertaining Sherlock set pieces and the show reaching too far to set up a surprising endgame.

It feels like Holmes and Watson's relationship has finally been restored. The introduction of the mysterious and dangerous Eurus feels like a bold direction in which to take the final episode.
