This starts with the death of a QC, Elizabeth Glendenning. But, knowing her death might be approaching, she has put a number of things in motion, to draw her old colleague at Chambers, Anslem (now a monk), into finish the unraveling she's started. It gets a bit convoluted, and explores that area between black & white, where things are morally in shades of grey. A bit like life, it doesn't have a happy ending, it just has a point at which the story ceases to be told. Very intriguing.
