Sherlock depicts "consulting detective" Sherlock
Holmes (Benedict Cumberbatch) solving various mysteries in London. Holmes is
assisted by his flatmate and friend, Dr. John Watson (Martin Freeman), who has
returned from military service in Afghanistan with the Royal Army Medical
Corps. Although Metropolitan Police Service Detective Inspector Greg Lestrade
(Rupert Graves) and others are at first skeptical of Holmes, over time his
remarkable intellect and powers of observation persuade them of his value. In
part through Watson's blog documenting their adventures Holmes becomes a
reluctant celebrity, with the press reporting on his cases and eccentric
personal life, and both ordinary people and the British government ask for his
help.
Although the series depicts a variety of crimes and perpetrators, Holmes'
conflict with archnemesis Jim Moriarty (Andrew Scott) is a
recurring feature. Molly Hooper (Louise Brealey), a pathologist at St. Bart's
Hospital occasionally assists Holmes in his cases. Other recurring roles
include Una Stubbs as Mrs Hudson, Holmes and Watson's landlady, and series
co-creator Mark Gatiss as Holmes' elder brother and government official
Mycroft.
The library has the first three seasons.
