Continuity mistake: The brownstone has two front doors, an outer door and an inner door. In scenes before this one and after this one, the outer door is made of wood and the inner door has a large glass panel, at the top, but in this episode the outer door has a large glass panel, at the top, so they can see who it is before opening the door.
Elementary (2012)
1 continuity mistake in The Long Fuse - chronological order
Starring: Lucy Liu, Aidan Quinn, Jonny Lee Miller, Jon Michael Hill
While You Were Sleeping - S1-E2
Other mistake: When Sherlock was slapped, he later says he was surprised because the girl who slapped him was a "lefty." Then he rubs his right cheek and says it's leathery from all the slaps he's gotten, while the left is soft. This is backwards - anyone hitting him with their right hand would hit his left cheek.
Incel: Who are they?
Sherlock: That's Homeland Security.
Incel: But...you promised you wouldn't tell them about me if I talked to you!
Sherlock: Yes, but you play den mother to a pack of would-be rapists and mass shooters, so you can see how lying to you would be the highlight of my day. Look on the bright side - you don't seem to enjoy the company of women, and that shouldn't be a problem for the next five to ten years.
The Hound of the Cancer Cells - S2-E18
Trivia: "The Hound of the Cancer Cells" is a loose reference to "The Hound of the Baskervilles", perhaps the most famous of the four Sherlock Holmes novels.
The Rat Race - S1-E4
Question: I don't see her listed on the credits in beginning or any other website inquiries, but is that Tyne Daly playing the character Peter's secretary?
Answer: I'm the same person who asked this question. I discovered it was Molly Price whom I recognized from Third Watch.
Cathrine R
It should be noted Donna was Jim Fowkes‘ secretary. Donna killed Peter.
