As Sherlock attempts to comfort John Watson after his wife's death, entrepreneur and apparent philanthropist Culverton Smith tests a new drug on his employees and his daughter Faith to make them forget his confession that he plans to commit murder. Faith retains a partial memory and approaches Sherlock to identify a likely victim but her disappearance, and his descent into drug abuse, lands him in Smith's hospital and at his mercy. Though Sherlock is not as helpless as he appears and has his own way of trapping Smith, the final shock is reserved for Watson as his new therapist springs a terrible surprise on him.

When Lady Smallwood gives Mycroft her business card, her name is displayed as Lady Alicia Smallwood. As the wife of the late Lord Smallwood, she would be styled as Alicia, Lady Smallwood. She would only be titled "Lady Alicia Smallwood" if she were the daughter of an earl, marquess or duke and had married a commoner, in which case she would never have been referred to as Lady Smallwood. Even if she were afforded the courtesy title "Lady" by birthright and even if her maiden was also coincidentally Smallwood, the rank of her husband would take precedence, and she would never be styled as Lady Alicia Smallwood.

Oh My Gosh!
9 January 2017 | by HitchcocSee all my reviews

This is one of the finest hour and a half periods I have ever spent watching a screen. After a rather pedestrian beginning last week, I thought that perhaps the madness that was Sherlock may have been derailed. Benedict Cumberbatch is everywhere these days. He has become one of our premier actors. So in my mind I thought perhaps he had to phone this one in. Just the opposite. With Watson grieving and being pulled every which way, Sherlock begins the process of facing off against a criminal named Culverton, who is probably as vicious and ugly as any of the villains I've seen. He sells things, he basically owns a hospital where the employees are terrified of him, and he is seen as a great humanitarian. Somewhere along the line, Holmes realizes that the man is a serial killer. It makes the newspapers and instead of being indignant, Culverton invites Sherlock and Watson to visit the children at the hospital. What transpires is one of the wittiest, most delicately constructed plots I have ever encountered. Every twist and turn is done with care and precision. I can't give away too much, but there is a bonus as well. We are left with something unexpected to propel us into the third episode. Perhaps the best thing on television.
