Don't Ever Look Back by Daniel Friedman
Retired police detective Buck Schatz is crankier than usual as he spends his days doing heavy physical therapy while living in a retirement home. His slow descent into dementia is only making things worse. When a criminal named Elijah that Buck knew forty years ago visits and asks Buck to help him turn himself into the police for past crimes and to help shield Elijah from the people that are after him, Buck agrees. However, in meeting with Elijah, Buck recollects the case that brought them together in the first place and finds himself deeply involved, despite his own failing physical and mental health, in Elijah's criminal activities yet again. Don't Ever Look Back will be published in April.
