Midsomer Murders >> Season 9

Barnaby and Jones investigate the shooting of a blackmailer, Martin Barrett. But he had so many victims, they are spoiled for choice for a suspect. Then one of his victims, Sir John Waverley, gets another demand. The trail leads them to the seaside and diving for treasure on an uncataloged wreck.

The elderly Sir Freddy Butler has invited both his ex-wives, Annabel & Lucinda, to stay with him and his current wife, Tara. When he dies suddenly of a heart attack, the bitter rivalry between the three and Sandra, the wife of his heir, comes to the surface, with murderous consequences. To solve the mystery, Barnaby must unravel paternity questions about some of the residents of the hall, and find the legendary missing emeralds.

The village of Midsomer Barton is celebrating Oak Apple Week when a local single mother, Marion Slade, is found drowned in the village stream. It looks like suicide, and that she was driven to it by grief over the death, eight years before, of her daughter, Bella, a local beauty pageant winner. Barnaby investigates and is shaken by two villagers who look like murder victims from his past. Then another body is discovered and it appears that the festivities have stirred up a cocktail of adultery, contempt, unrequited love and revenge in the village. And it all appears to center around Bella Slade.

A couple who have been searching the Midsomer area for a suitable property to renovate, Peter & Caroline Cave, are found brutally garrotted in their car outside a supposedly haunted dilapidated old cottage in the woods near Midsomer Newton. There are several other people interested in buying the house, but are they desperate enough to murder potential rivals? Barnaby investigates, with the assistance of PC Ben Jones, who he temporarily appoints Detective Constable, in the absence of DS Scott. Joyce Barnaby is helping a local group of conservationists identify architecturally important buildings in the area, and is asked to investigate the same cottage, potentially putting her in danger. Barnaby then discovers that there is something odd about the person selling the cottage.
