Ep 1. The Further Adventures

In the season 7 premiere of Elementary, entitled "The Further Adventures," we find Sherlock and Joan recovering from the events of the previous season's finale. They are both dealing with their own struggles in their personal lives - Joan is considering taking her relationship with Andrew to the next level and Sherlock is grappling with trying to stay sober.

Their peace is soon interrupted when Holmes is contacted by a missing person, a woman named Shinwell Johnson. Initially, Joan is against working on the case, as she believes that Sherlock is prone to relapse when things don't go their way. However, as Shinwell is someone that Joan had previously worked with on a case, she agrees to take the case with Holmes.

Shinwell's return is both surprising and confusing, as he was thought to be dead. Joan finds out that he was placed in witness protection after he became a cooperating witness in a case that she previously worked on. While initially wary of Shinwell's intentions, Joan and Sherlock decide to help him. Shinwell claims that he needs their help as he's being pursued by someone who is trying to kill him.

The case takes them to Brooklyn, where they meet with one of Shinwell's old associates, who is also a witness. They soon find out that the killer is after all the witnesses who testified against him, and the killer has already taken out one of them. Joan and Shinwell have an encounter with the killer, which puts their lives in danger.

The team tries to figure out the identity of the killer before he strikes again. Sherlock uses his expertise in chemical compounds to come up with a solution that will allow them to track the killer. However, this plan is complicated by Shinwell, who has his own agenda and is not willing to follow Holmes' instructions.

As the investigation continues, the team uncovers a plot that goes deeper than they originally thought. The killer has help, and they are on a mission to tie up all the loose ends and eliminate the witnesses once and for all.

The tension between Joan and Sherlock continues as they both deal with their individual struggles, with Joan dealing with her growing feelings for Andrew and Sherlock fighting to stay sober. However, despite their personal challenges, they put their heads together and manage to solve the case, leading to a dramatic conclusion.

Overall, "The Further Adventures" serves as a strong season opener for the final season of Elementary. It's full of action, suspense, and emotion.
