Low Winter Sun is a two-part British crime drama miniseries that first aired on Channel 4 in 2006.
The series, written by Simon Donald, stars Mark Strong as Detective Sergeant Frank Agnew, a police officer who murders a fellow officer and believes he has committed the perfect crime.
The miniseries was later adapted into a 10-episode series by AMC, with Strong reprising his role as Detective Agnew.
They stage the crime to make it look like a suicide, but soon their actions spiral out of control and they find themselves caught up in a web of deceit, betrayal, and murder.
Andrew Anthony of The Observer praised the series, declaring it 'A splendid, if bleak and brutal, piece of stylised realism' and saying 'I doubt that there is an actor working in Britain who does taut and intense better than Strong'.
