Silk is a British television drama series produced by the BBC and first shown in 2011. Written by Peter Moffat, the series follows a set of barristers, and what they do to attain the rank of Queen's Counsel, known as 'taking silk'. Passionate defence barrister Martha Costello faces challenging cases and surprising clients, which test her faith in the criminal justice system. Gifted colleague Clive Reader is called to the bar with her. They work hard with pupils, Nick Slade and Niamh Cranitch, but ultimately only one can eventually be taken on as a member of chambers.






With female QCs (Queen's Counsel) or 'silks' in a tiny minority, barrister Martha Costello, of the Shoe Lane Chambers, is anxious to join that elite number by progressing through the courts. Following a successful acquittal in a murder trial she is given two cases to defend at short notice. Mercedes Cordoba, a pregnant drugs mule. The other is Gary Rush, charged with robbing and assaulting elderly war hero Michael Dodd.
Martha's day begins badly when she discovers that she is pregnant and gets worse when she finds that scheming Billy has her down to defend Alan Bradley,accused of raping ex-girlfriend Annie with Reader - who has just bedded Niamh, his junior - prosecuting. In court Reader plays to the gallery, Annie appears fragile and Bradley accuses Martha of being too soft on her. Niamh gets bail for Gary Ross, whom Martha recently got off a robbery case but Martha doubts his innocence when, a WWII medal, appears in her locker.
Martha defends homeless teen-aged "rent boy" Mark Draper,charged with indecency in a public lavatory. Niamh and Nick separately represent a warring couple charged with owning dangerous dogs. Nick wins his case by chance while the more competent Niamh loses. She gets the next brief but Nick has to represent the third defendant in the indecency charge when his barrister falls ill.
