DCI Tom Barnaby (John Nettles) and his ever-faithful sidekick, DS Gavin Troy (Daniel Casey) investigate the murder of a lonely lady named Agnes Gray (Denyse Alexander) whose favourite way of spending her time was helping animal conservation charities and practicing her new-found Catholic faith. The officers can find no reason why anybody would want to kill her and her only family, a cousin, the snobbish and wealthy Esslyn Carmichael, (Nicholas Le Prevost) clearly doesn't give a hoot that she is dead, being only interested in anything she may have left him in her will.
Esslyn Carmichael is to play the lead role of Salieri in a local stage production of "Amadeus" and Tom's wife, Joyce (Jane Wymark)has a non-speaking part as Salieri's cook. Somewhat reluctantly, Tom agrees to help with the scenery while Joyce becomes more and more nervous about her performance in spite of having no lines.
The flamboyant and talented Nicholas Bentley (Ed Waters) is to play the role of Mozart in the production and it's very clear that he, and not Esslyn Carmichael is the true star. Tom's daughter, Cully, (Laura Howard) is also quite taken with Nico herself and she is one of the many people who can see that he certainly has a gift for acting.
The totally obnoxious and over the top director, Harold Winstanley (Bernrad Hepton) drives the cast mad with his need for absolute perfection and his fanciful stories of working with "the greats" of British theatre. Fortunately, most don't listen to himand just get on with the job at hand.
On opening night, however, things get a little messy when Esslyn Carmichael cuts his own throat on stage with a weapon that was supposed to be merely a prop. The list of potential suspects is indeed a long one for someone who was so thoroughly disliked, including by his pregnant wife, Kitty (Debra Stephenson) and his very bitter ex-wife, Rosa. (Sarah Badel). The questions that Barnaby and Troy must answer are first of all, did the same person kill both victims and if so, what was the motive? Is the truth buried behind tales of adultery, stolen art, and revenge or is it something as yet undiscovered? Watch this terrific episode and see for yourself as the intrepid investigators sort out the puzzle piece by piece.
