Sherlock (Jonny Lee Miller) is known for his brilliant deductive technique and it will come as no surprise that the New York Police Department (NYPD) will tap into his talent once in a while. In the upcoming episode of the CBS series "Elementary," the Narcotics Division will ask him to organize the "perfect" raid.

In "A View with a Room," CarterMatt reports that Captain Gregson's (Aidan Quinn) colleagues will approach Sherlock with an offer. They need to penetrate a compound protecting a biker gang being suspected of drug activities. "Heavily armed and virtually impenetrable," the place has been a source of headache for the agents, as they think of a way to get inside it. They need a flawlessly orchestrated heist to turn the tables around, and Sherlock is the man that they are looking for. Will his cunning be enough to succeed in the mission?

Meanwhile, Joan (Lucy Liu) will learn surprising information about her partner. Fiona (Betty Gilpin) will reportedly ask the consultant's help in a new case and this will lead to the discovery. They have worked together before and established a good relationship. After spending a lot of time together, Sherlock still manages to surprise Joan. What detail about him will she know this time?

Last episode, Sherlock and Joan took on a case involving two murders, a woman of a local roller derby team and a homeless man. When the morgue that was holding their bodies blew up, the NYPD was tapped to investigate. At first, the trail led to a cartel planting the bomb, but it soon became clear that the woman was the key to both crimes.

The victim had an admirer, but since she had a boyfriend, he had no choice but to fantasize about her. He hated his obsession and plotted of ways to kill her, which he kept in a journal. His father saw the log and feared that the son would someday turn his illusion to a reality. The old man decided that it was best to murder the woman right away. The homeless man was just collateral damage. He bombed the morgue to make sure no evidence would lead back to him.

"Elementary" season 4 airs Thursdays at 10 p.m. EST on CBS.
