The Scarecrow is a novel featuring newspaper reporter Jack McEvoy. He was the main protagonist in one of Connelly's previous novels, The Poet. FBI agent Rachel Walling is back too. She and Jack were lovers in The Poet, and things heat up again.
Jack has just been laid off at the paper where he works and he's determined to write a last best story. When he stumbles on a serial killer called the scarecrow he has his chance. But this killer is part of a team and the team is good at what they do. They make Jack's life very interesting. Very highly recommended.
