Memento MoriFollowing Lizzie's death Kavanagh takes on the case of a doctor, Felix Crawley, charged with killing his depressive,and unfaithful,wife Ann with an overdose of lithium. The doctor claims he has treated Ann in secret because of the shame of her disorder and the death was accidental. Kavanagh takes on prosecution witnesses,including Ann's lover and her young niece,whose advances Felix spurned, and,as the case draws to its verdict, comes to appreciate that he is identifying with his bereaved client.Care in the CommunityKavanagh and chambers head Peter Foxcott go to Kavanagh's home town, Bolton, where Kavanagh is defending Debbie Sattenthwaite and Mark Holmes, charged with killing their fourteen month old daughter. Unfortunately the couple's evidence suddenly starts to clash as Mark changes his story and Foxcott is shocked at the way Kavanagh goes for Debbie, requiring his intervention to assist his colleague.Briefs Trooping GailyKavanagh, who is still mourning his wife's death, has to defend a woman charged with killing her abusive husband. Despite having a good case for manslaughter, she seems determined to plead guilty to murder. Meanwhile Jeremy is torn between the demands of his lead role in a Gilbert & Sullivan production; and a charge of professional misconduct for looking at a defense brief.Bearing WitnessKavanagh's personal views and professional pride clash when his clerk Tom asks him to represent a former girlfriend Susannah Emmott. After they split she was briefly married to a Jehovah's Witness whose beliefs she took on before he became disillusioned and left her. She has a son, Luke, aged thirteen, whose father knows nothing of him and who needs a life-saving blood transfusion, which is against Susannah's religious beliefs. Jeremy gets himself involved with a group of tree-huggers out to save local woodlands.Innocency of LifeKavanagh successfully defends a young vicar, Ian Winfarthing,when pub landlady Anne Murchison accuses him of sexual harassment. But when Anne is charged with killing her drunken, bullying husband,Tom, Ian comes forward to claim that he and Anne were lovers, the harassment case being a smoke-screen and they were in bed together when Tom died. Jeremy dates a glamorous aristocrat, throwing her over for his career's sake when she tells him she is pregnant, and later finding he has dumped a millionairess.Dead ReckoningKavanagh goes to Yorkshire fishing port Stainmouth to prosecute Roy Lawrence for negligence after his apparently unseaworthy trawler sank,claiming five lives including Roy's son Paul. The defence claims that a submarine collided with the boat, a claim that becomes more and more likely. Roy is popular in the bereaved community and even Emma, Kavanagh's junior, feels sorry for him, but Kavanagh believes Roy had his own agenda and is not the philanthropist he seems. He also averts a chambers crisis by dissuading Tom from leaving.
