Exit Lines — Reginald Hill

Three old men die on a stormy November night: one by deliberate violence, one in a road accident and one by an unknown cause. Inspector Pascoe is called in to investigate the first death, but when the dying words of the accident victim suggest that a drunken Superintendent Dalziel had been behind the wheel, the integrity of the entire Mid-Yorkshire constabulary is called into question. Helped by the bright but wayward DC Seymour, hindered by 'Maggie's Moron', the half-witted Constable Hector, Peter Pascoe enters the twilight and vulnerable world of the senior citizen -- to discover that the beckoning darkness at the end of the tunnel holds few comforts.
