The story is about the murder of Venetia Aldridge, a QC (Queen's Council) in a London "Chambers" and a very ambitious barrister who has a track record of winning her cases. She doesn't necessarily prove that her clients are innocent, she simply disproves the prosecution's case against them. In the course of her career ,she has made enemies and one of them kills her and she is found in a very ritualistic setting.
