DNF: My Brother's Keeper by Keith Gilman, 2011, 9780727881021.
Second book featuring ex-cop Philadelphia policeman Lou Klein. I just couldn't get into the story.
Klein, now a private dick, gets a case from his neighbor, and former police colleague, to help out the neighbor's sister. Klein used to be hot for the sister and she since married a mob linked guy. Klein started looking and I quit.
