P.D. James: Death Of An Expert Witness
Chief Superintendent Adam Dalgliesh of Scotland Yard, young for his senior rank and suffering the effects of his own personal tragedy, must wade through a complex web of desperation, revenge, blackmail and secret love to solve a series of murders at a government forensic lab.
Dalgliesh has been hunting a "back seat strangler" in London. When a young woman is found strangled, her body sprawled over the back seat of a car abandoned in a bleak country quarry, he is rushed to the scene. Convinced that this murder is not linked to his investigation, Dalgliesh returns to London only to be urgently recalled to investigate when a senior forensic scientist is found murdered at a government facility not far from the quarry. Dalgliesh has to break through the wall of fear surrounding the tight-knit - and tight-lipped - staff before he can bring the killer, or killers, to justice.
