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.
