She's applied to be appointed Queen's Counsel – one of the most prestigious accomplishments in an English lawyer's career – a process known as "taking Silk." To be unswervingly principled is difficult enough; but Martha's rival, charming and ruthless Clive Reader, is also in competition for QC. And only one of them will succeed.
