Watson's P226R is likely meant to be his army service pistol. Although the P226 is used in the British Military, it is mainly used by Special Forces and it is rare to be held by Infantry, where the Browning Hi-Power or the Glock 17 Gen 3, which is phasing out both handguns for its high magazine capacity and reliability, are more common. The P226 was issued widely as an Urgent Operational Requirement (UOR) during British Operations in Afghanistan.

Certain 1890s scenes in semi-period "The Abominable Bride", could be seen to imply that the entire 21st "modern" period settings, of the rest of the entire run, could actually be the drug-induced (mind palace) hallucinations or imaginings of the 1890s period Sherlock Holmes, thus turning the entire series as one long alternate version of "reality".

The forensic specialist Anderson thinks the victim was trying to write the German word for revenge, but Sherlock deduces that the victim died before finishing writing "Rachel."

Originally this was shot as a 60-minute one-off TV movie. Its costs ballooned to an almost unheard-of one million pounds, and rumors flew that the BBC would pull the plug and leave it unaired. Instead, they asked Mark Gatiss and Steven Moffat to turn the whole thing into a series pilot. That would entail making it longer. And they wrote a longer script. But they couldn't get the same cinematographer back, and didn't think the added scenes would be consistent with what they had already filmed. So they shot the whole pilot over.

In this new series, Dr. Watson served as a captain (and medical doctor) in the 5th Northumberland Fusiliers, who served in Afghanistan. The 5th Northumberland Fusiliers did indeed serve in Afghanistan during the Second Anglo-Afghan War (1878-1880). The first story of the old Sherlock Holmes series takes place in 1881. However, the 5th Northumberland Fusiliers was renamed the 'Northumberland Fusiliers' in 1881 (the 5 was dropped from the title), which means that the modern Dr. Watson serving in the 5th Northumberland is a salute to the old legacy. The old 5th Northumberland was last named the 'Royal Northumberland Fusiliers' and was amalgamated in 1968. Watson's current regiment would be the 'Royal Regiment of Fusiliers', which has served in Afghanistan repeatedly over the last 16 years.

Some 1890s scenes in the special 'The Abominable Bride' imply that all the 21st-century 'modern' period settings in the rest of the series may actually be drug-induced (mind palace) hallucinations or dreams of an 1890s-era Sherlock Holmes, thus making the entire series a long alternative version of 'reality'.

In the second episode of season 1, Sherlock tells John about the time he 'argued' with a chip-and-pin machine; John explains that it was mostly the machine insulting him while he 'sat there'.

Watson's P226R pistol most likely represents the weapon he used during his military service.

In the original story A Study in Scarlet, Scotland Yard finds the word 'rache' written in blood on the wall, and Lestrade thinks the victim was trying to write Rachel. Sherlock, however, says it means revenge in German. In A Study in Pink (2010), the victim scratches 'rache' on the floor, and while forensic specialist Anderson thinks the victim was trying to write revenge in German, Sherlock deduces that the victim died before he could write 'Rachel.'

In this new series, Dr. Watson served as a captain (and medical doctor) in the 5th Northumberland Fusiliers, having served in Afghanistan. The 5th Northumberland Fusiliers did indeed serve in Afghanistan during the Second Anglo-Afghan War (1878-1880). The first story of the old Sherlock Holmes series takes place in 1881. However, the 5th Northumberland Fusiliers was renamed the 'Northumberland Fusiliers' in 1881 (the 5 in the title was dropped), meaning that the modern Dr. Watson's service in the 5th Northumberland is a salute to the old legacy. The old 5th Northumberland was last named the 'Royal Northumberland Fusiliers' and was amalgamated in 1968. Watson's current regiment would be the 'Royal Regiment of Fusiliers,' which has served repeatedly in Afghanistan over the past 16 years.

In the first episode of Season 2, Sherlock mentions the 'legend' that the Allies knew about the Coventry bombing and allowed it to happen in order not to reveal that they had cracked the Enigma code. In The Imitation Game (2014), Benedict Cumberbatch plays Alan Turing, and this scene is brought to the screen.

In the first episode of Season 4 (The Six Thatchers), as a harbinger of the main villain of the following episodes, Culverton Smith, when Dr. John H. Watson (Martin Freeman) gets off the bus and sees E (credited as Elizabeth, played by Sian Brooke), a poster with Smith's face (later played by Toby Jones) is visible at the bus stop. The poster is visible only for a moment and its slogan reads '[_] will be murder,' with only that much legible because Watson's body blocks the rest of the poster.

Some of the 1890s scenes in the special 'The Abominable Bride' imply that all the 21st-century 'modern' period settings in the rest of the series may actually be drug-induced (mind palace) hallucinations or dreams of an 1890s-era Sherlock Holmes, thereby turning the entire series into a long alternative version of 'reality.'

In the 2nd episode of season 1, Sherlock tells John about the time he 'argued' with a chip-and-pin machine; John explains that it was mostly the machine insulting him while he 'sat there'. This later resembles John and Sherlock's arguments; John mostly shouts while Sherlock sits and listens. John even calls Sherlock a 'machine' during one of these arguments at the Reichenbach Falls.

Show runners Mark Gatiss and Steven Moffat previously worked together on Doctor Who (2005). There is actually considerable overlap between the characters. The Doctor has been played by Peter Cushing and Tom Baker, both of whom have also played Sherlock. The tenth Doctor (David Tennant) at one point claims to be a student of "Dr. Bell," a reference to Joseph Bell, the inspiration for Holmes. Brian Cox played Bell in The Strange Case of Sherlock Holmes & Arthur Conan Doyle (2005). Cox has also played Doctor Who creator Sydney Newman in An Adventure in Space and Time (2013).

In the Season 2 premiere, Sherlock talks of the 'myth' about the Allies knowing about the Coventry bombing and still letting it happen so that they don't disclose that they have cracked the Enigma code. In the movie The Imitation Game (2014), Benedict Cumberbatch plays Alan Turing and the entire scene is played out on the screen.

In this new series, Dr. Watson used to be a Captain (and medical doctor) serving with the 5th Northumberland Fusiliers deployed to Afghanistan. The 5th Northumberland Fusiliers did indeed serve in Afghanistan in the Second Anglo-Afghan War (1878-1880). The first story of the old Sherlock Holmes series took place in 1881. The 5th Northumberland Fusiliers, however, was renamed "The Northumberland Fusiliers" in 1881 (no 5th left in the title), which means the modern Dr. Watson's service with the 5th Northumberlands is a nod to its old heritage. The former 5th Northumberlands evolved into its last formation named "Royal Northumberland Fusiliers" and was amalgamated in 1968. Watson's current regiment would be "The Royal Regiment of Fusiliers", with whom he has served in Afghanistan multiple times over the past 16 years.

Sherlock sometimes uses a memory technique that he calls a "Mind Palace." This is not an invention of the screenwriters; rather, it is a method of aiding memory that dates back to Ancient Rome called the "Method of Loci". One of history's most famous real-life practitioners was the sixteenth-century Italian Jesuit missionary Matteo Ricci, who introduced the method to China.

It becomes very obvious when binge watching the first 14 episodes, including "Many Happy Returns", but excluding the original version of the pilot, that seasons 1-4 actually subtly form one long story arc, eventually leading up to the shocking revelation of what the "Redbeard" references are.

Certain 1890s scenes in the semi-period "The Abominable Bride" could be seen to imply that the entire 21st-century "modern" period settings of the rest of the entire run could actually be the drug-induced (mind palace) hallucinations or imaginings of the 1890s-period Sherlock Holmes, thus turning the entire series into one long alternate version of "reality".
