The Elementary Season 4 DVD sees the return of Jonny Lee Miller and evergreen Lucy Liu along with the ageless Aidan Quinn.
Elementary 4 starts with Sherlock facing the consequences of his relapse, and his father arrives to try to fix the situation. Joan and Sherlock, trying to get back on NYPD's good side, search for a missing woman working the theory she was killed by her husband.
Holmes attempts to rebuild his life in the wake of his attack on Oscar and subsequent relapse. Due to his violent actions, Sherlock's partnership with Watson and their consultancy with the NYPD are in jeopardy. As he awaits news on whether or not he will face criminal charges, the case of a missing woman allegedly killed by her husband lands in his lap, just in time to distract him from the impending arrival of his estranged father, Mr. Morland Holmes.
