Always Say Goodbye (Lew Fonesca Series #5) in Bloomington, MN

Four years ago, Lew Fonesca's wife Catherine was struck and killed in a hit-and-run. Grief-stricken, he fled to Chicago and wound up in Sarasota, Florida where he's made a living as a process server. Four years on, he's still savoring his depression like fine wine, and his therapist—and sparring partner—has had enough. It's time, she tells Lew, to get on with his life. Time to go back to Chicago and find out what really happened to his wife.
Lew hates to admit it, but Ann Horowitz might be right. Even if it kills him, he has to know the truth about his wife's death. So he returns to his home, his family, his friends—and a mystery.
He's resolved to dig until he finds out who killed his wife. In doing so, he'll uncover both sweet and painful memories of his past. He'll also confront a murderer who'll not hesitate to kill again to make sure hidden secrets stay buried.
