Harry Bentley's Second Chance by Dave Jackson
"To be a father like God, to have God as his father ... perhaps Harry was being given a chance at both." Retired Chicago cop, Harry Bentley, was lying low. He'd blown the whistle on a gang of rogue cops and was awaiting the day when Internal Affairs would call him to testify and help put their leader, Lieutenant Matty Fagan, behind bars. His cover was working as a doorman in a luxury highrise on Chicago's lakefront. Then Gabby Fairbanks and her husband moved into the building's penthouse. She brought home a bag lady, got a job at the Manna House Women's Shelter, found her life falling apart, and managed to entangle Harry in the whole affair.
