Easily 4 Stars and maybe more when I think a bit on it. So very dark. Evil exists and Lehane brings you face-to-face with some bad people. I don't think the Boston Chamber of Commerce is a fan of his...his portrait of the seamier side of Boston isn't one to make you want to live there. Kenzie and Gennaro are so appealing and real. You will learn how to measure a bridge (or any distance) in 'smoot' measurement units. Read the book to find out.
