The hospital scenes are spiced up by Aline Mowat as Sister Nessie Maclean who provides strict control with a sense of humour. Lisa Eichhorn, however, plays a flat Dr. Millicent van Buren, author of the book on the crime. The role of Morse's girlfriend Adele who cares for him is again played with grace by Judy Loe. The plot about the young woman Joanna Franks(Juliet Cowan) found dead in the canal and subsequent trial is realistic with Liam Barr effectively playing the young boatman (Thomas Wootton) and Jeff Nuttall with a decent portrayal of the trial judge(Mr. Justice Benham). Matthew Finney is excellent as the young graduate intern who Morse enlists to help investigate the crime and evidence relating to it. This allows the introduction of interesting scenes at a local archive overseen by Susan(Sarah Lam), and subjecting the evidence to modern forensic tests by Dr. Laura Hobson (Clare Holman) who does it with flair. The visit to a grave in Ireland provides a fine ending for the story.
