Mrs. Lucas (Elementary)

Mrs. Lucas is an unseen villainess mentioned in Elementary's seventh and final season opener, "The Further Adventures" (airdate May 23, 2019).
Mrs. Lucas is the wife of Eduardo Lucas, who was murdered shortly before the events of the episode (most likely in between Seasons Six and Seven). Joan Watson was on the case, and it was revealed that Lady Hilda was suspected of the murder. 
As Joan informed Sherlock Holmes, Mrs. Lucas was the killer, as she suspected her husband of having an affair (most likely) with Lady Hilda, and in response, she killed Eduardo. Blood evidence on the home's carpet revealed the truth, and it can be assumed that the evil Mrs. Lucas was arrested (off-screen) for her husband's murder.
