Death of an Expert Witness on AllMovie

Roy Marsden stars as Commander Adam Dalgliesh in this made-for-television adaptation of the novel by P.D. James. Edwin Lorrimer (Geoffrey Palmer) is a noted forensic scientist who is often called upon to testify in court proceedings as an expert witness, and when he dies as a result of foul play, Dalgliesh is called in to investigate. Lorrimer was killed inside the building where he worked, and given the tight security of his offices, initial police research assumes that someone who worked alongside Lorrimer is the most likely culprit. However, the longer Dalgliesh looks into the murder, the more he's convinced the answer lies elsewhere. Originally aired as a three-part miniseries, Death of an Expert Witness also features John Vine, Barry Foster, and Brenda Blethyn.
