What Is Sherlock About?
BBC’sSherlockadapts from short stories by Arthur Conan Doylefrom his various books on the famous fictional detective. However, the series is set in the present times and reshapes the characters accordingly. Although each episode follows a crime procedural format and explores different crimes and criminals, Holmes’ and Moriarty’s conflict remains a recurring, underlying theme. Here’s the official synopsis ofSherlock:
Sherlock depicts “consulting detective” Sherlock Holmes (Benedict Cumberbatch) solving various mysteries in modern-day 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 suspicious of Holmes at first, over time, his exceptional intellect and bold 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. Both ordinary people and the British government ask for his help.
