Death of an Expert Witness

1983 • Crime, Drama, Mystery

When Dr. Edwin Lorrimer, a forensic scientist working at a private laboratory is found killed, Detective Superintendent Adam Dalgliesh is sent to investigate. Dalgliesh had been in the area a few months previously investigating the murder of a young woman found in an abandoned car. There are several suspects: Lorrimer's subordinate, Clifford Bradley, who despises him; the new head of the laboratory, Maxim Howarth, who is jealous of his sister's relationship with him; a colleague, Paul Middlemass, who had a fight with Lorrimer. There is also a gruff and likely unethical policeman who was on the grounds of the laboratory at the time of the killing and a local pathologist who is raising his two young children after his wife leaves him for another man. When one of the suspects is also murdered, Dalgliesh learns a key piece of information.

Why you should read the novel

If you truly want to experience the depth and brilliance of Death of an Expert Witness, the novel is the key. P. D. James weaves a complex tapestry of psychological intrigue, allowing readers intimate access to the inner lives of suspects and sleuths alike in a way no screen adaptation can fully replicate. The richness of her narrative voice sharpens every motive and atmosphere, evoking an authentic sense of place and time that immerses you in the heart of English forensic drama. Reading the novel offers subtleties of characterization often missed or condensed for television pacing. James's nuanced portrayal of Adam Dalgliesh invites reflection on morality, professionalism, and the human psyche. The slow-burning suspense, meticulous police procedure, and layered personal dynamics are best savored on the page, where every clue and implication is given its due weight. Moreover, the book's literary craftsmanship heightens the experience, with evocative prose and meticulous attention to forensic detail. Fans of crime fiction will relish the opportunity to piece together the puzzle alongside Dalgliesh, enjoying the narrative’s intelligent complexity and slow reveal, something only the author’s original pages can deliver.

Adaptation differences

One of the most prominent differences between the adaptation and P. D. James’s novel is the depth of the character development. While the TV series captures the essential aspects of Adam Dalgliesh and his investigation, the novel delves much more deeply into the backgrounds, motivations, and psychological complexities of all its characters. In the book, side characters such as the staff of Hoggatt’s forensic laboratory, and even minor suspects, are given rich inner lives, providing more context and tension. The television adaptation streamlines the plot for brevity, condensing timelines and omitting certain subplots. Some nuanced relationships and personal histories, which develop gradually in the novel, are simplified or altogether absent in the series for the sake of visual pacing. This means that the intricate web of personal animosities and alliances that lend the book its thick atmosphere are slightly diluted on screen. Another key difference lies in the portrayal of forensic and police procedural details. The novel lingers on procedural accuracy and the scientific method, immersing readers in the world of criminal forensics. The adaptation, conversely, often summarizes these processes or presents them more briskly, prioritizing narrative movement over technical depth. Lastly, P. D. James’s evocative prose creates a distinctive, almost claustrophobic sense of place within the laboratory and the Fenland setting that the adaptation cannot completely mirror visually. The TV series, while visually atmospheric, does not linger on descriptive scenes or internal monologues the way the book does, thus some of the novel's tension and subtlety is less forceful in translation to screen.
