With her usual grace and compassion, Mary Higgins Clark's book The Second Time Around explores the mind of a mass killer; in fact, a good part of the book is told from his point of view. It's a complicated plot with everything spinning off from a corporate crime committed by a character who then dies in a small plane crash. As is usual with her books - indeed most mysteries, there is the sense of a clock ticking as the book nears its end: will the culprit be caught before...whatever?
Very well done, and a classic Higgins plot line.
