Story Structure — 5 Plot Phases

Season 1: Partnership and Challenges

Sherlock and John meet and establish a shared life at Baker Street while investigating poison-pill deaths and a coded bank case. Moriarty's timed challenges turn the investigative partnership toward a direct criminal contest.

Season 2: Secrets and Threats

The cases involve Irene Adler's guarded phone, a frightening investigation on Dartmoor, and Moriarty's coordinated heist. Moriarty's campaign against Sherlock culminates in a rooftop confrontation and threats against people close to him.

Season 3: Reunion and Marriage

Sherlock returns after his reported fall, but John is angry that he was not told the truth. Their relationship resumes against the backdrop of John's wedding, before the Magnussen investigation exposes Mary's concealed identity and leads to Sherlock being shot.

Season 4: Grief and Crisis

The supplied Season 4 context describes Sherlock's narcotics relapse after Mary's death and his investigation of Culverton Smith. It also describes Eurus's attacks and the journey to Sherrinford, where Sherlock, John, and Mycroft discover that she controls the asylum.

Season 4 Context: Duplicated Adler Account

The supplied Season 4 Episode 1 text repeats the Season 2 account of the Adler phone commission rather than providing a distinct Season 4 event. It is therefore treated as a source-text inconsistency, not as evidence of a new seasonal relationship or plot development.
