David Baldacci's book "The 6:20 Man" features Travis Devine.  He is a West Point graduate, who after a couple of tours in Afghanistan and Iraq, finds himself back home looking for something a bit less exciting. That is how the 32-year-old winds up working as a junior associate in a Wall Street brokerage firm.  But trouble seems to find him when a woman who  mentored Devine is found hanging in a supply closet at the firm. What looked like suicide becomes a homicide -- and Travis Devine becomes a suspect.  "The 6:20 Man" is the latest addition to Rick's Reading List on KDKA Radio.
