I grabbed a paperback to read in the bath, just something I’d picked up at the library on impulse. I thought it would be a typical serial killer/procedural type mystery.It turns out to be a lot better than that. The book is The Fifth Angel by Tim Green. I’m at chapter 21, so I can’t be sure the book as a whole will fulfill its promise, but I’m hopeful. The writing is excellent with a smooth easy rhythm and avoids the obvious metaphors and analogies. Green makes the characters real and interesting, without gratuitous details. More importantly, the story poses a compelling ethical dilemma, one I will ponder for awhile.
