**The inspiration behind Dalgliesh—a streaming series starring Bertie Carvel now in its third season! In this page-turning installment in the bestselling Adam Dalgliesh mystery series from “the reigning mistress of murder” (Time), the Inspector must investigate the murder of a twisted forensic scientist and explore the dark secrets within his laboratory. When a brilliant forensic scientist is found murdered in his own laboratory, Scotland Yard is called to the scene. The victim, a well-respected, authoritative member of the scientific community, was unpleasant to and greatly disliked by those who worked closest to him, leaving detectives with a wealth of suspects and murderous motives. Inspector Adam Dalgliesh, an investigator with a poetic soul, is the one man who can sort through the lies, chasing down the truth behind the cover-ups, hidden agendas, and institutional secrecy. P.D. James deftly weaves another character-driven tale of intrigue in Death of an Expert Witness. Engaging and thrilling, she takes readers along with her troubled detective on a case rife with psychological thrills.
