A Study In Pink is the first episode of the BBC television series Sherlock which aired for the first time on 25 July 2010. The episode was written by Steven Moffat and directed by Paul McGuigan. It is loosely based on the Sir Arthur Conan Doyle story A Study in Scarlet, despite alluding to many other Conan Doyle stories.


John Watson, an ex-army doctor haunted by his experience serving abroad in Afghanistan, ran into an old friend Mike Stamford at Russell Square Park. After John brought up his problem of accommodation, Mike took him to St Bartholomew's Hospital to meet the consulting detective Sherlock Holmes. They both moved into 221B Baker Street, owned by Mrs. Hudson.

Sherlock was called by DI Greg Lestrade to investigate the "serial suicides", the suspicious deaths of Sir Jeffrey PattersonJames Phillimore and Beth Davenport. Sherlock and John went to the latest crime seen containing the body of Jennifer Wilson.


Allusions to Conan Doyle storiesEdit

A Study in Pink was roughly based on the Sir Arthur Conan Doyle story A Study in Scarlet. These allusions include:

  • Mike Stamford, the Barts teacher who introdcued Sherlock Holmes and John Watson, was based on "young Stamford" who did the same deed to the original Holmes and Watson.
  • The cabbie Jeff Hope bares many similarities to the cab driver Jefferson Hope in the Conan Doyle story A Study in Scarlet.
  • Jennifer Wilson was killed by Jeff in a house in Lauriston Gardens, Brixton, while the original killer Jefferson Hope killed his sole victim, Enoch Drebber, in the house at 3 Lauriston Gardens, off the Brixton Road.

There are many allusions to other Conan Doyle stories, including:

  • The student James Phillimore, who died after leaving his friend to collect an umbrella, originally appeared in the story The Adventure of Thor Bridge as an unsolved case of Holmes'. The case was about a man called James Phillimore who went inside his house to collect an umbrella and was never seen again.
  • Sherlock Holmes' deductions about John Watson's phone are very similar to a deduction the original Holmes made about a pocket watch in the novel The Sign of the Four.
  • When Sherlock uses three nicotine patch and calls the case a "three patch problem", this refers to the original Holmes' "three pipe problem" in The Adventure of the Red-Headed League.
  • The two texts that Sherlock sends John, reading "Come at once if convenient" and "If inconvenient, come anyway" refer to a telegram that the original Holmes sent to Watson in The Adventure of the Creeping Man.
