Immortal sergeant

Summary/Review: "On the eve of his unwelcome retirement, Jim Sargent (aka "Sarge") a grizzled, old-school detective, catches a break on a murder case that's haunted him for decades. Unfortunately, Sarge must drag his anxiety-riddled adult son, Michael, along for the ride or risk losing the lead forever. Can this dysfunctional duo overcome their own hang-ups, blindspots, and secrets to catch a killer?"--Amazon.
