Ep 21. Under My Skin

In the season 3 episode 21 of Elementary titled "Under My Skin," Holmes and Watson take up an investigation into a string of murders that have taken place in New York City. The murders seem to be eerily familiar with a case that Holmes had worked on in London years ago, where the murderer had never been caught.

As the investigation progresses, Holmes begins to realize that there may be more to the murders than meets the eye. The evidence points to the possibility of a copycat killer, but Holmes believes that there is something deeper going on. He becomes convinced that the original killer is somehow involved, and the person behind the new murders is trying to lead him to them.

As Holmes and Watson delve deeper into the case, they encounter resistance from the NYPD, who are afraid of stirring up old wounds. The investigation leads them to a high-security hospital where the original killer is being held. Holmes soon realizes that the killer is not only involved in the new murders but also has a deadly agenda of their own.

The episode is filled with tension and suspense as Holmes and Watson race against time to stop the killer before they strike again. With each twist and turn, they come closer to uncovering the truth and bringing the killer to justice.

As always, the chemistry between Jonny Lee Miller as Holmes and Lucy Liu as Watson is electric. The actors have developed a fantastic rapport over the course of the series, and their performances in this episode are no exception. The episode also features standout performances from the supporting cast, including Aidan Quinn as Captain Gregson and Jon Michael Hill as Detective Bell.

Overall, "Under My Skin" is a thrilling episode of Elementary that will keep you on the edge of your seat. With its intricate plot, well-developed characters, and excellent performances, it is a must-watch for fans of the series and anyone who loves a good mystery.
