A Pocket Full of Rye will see Miss Marple trying to solve her most compelling case yet.
Wealthy businessman Rex Fortescue (Kenneth Craham) collapses after his breakfast, poisoned by an extract from yew berries. A pocketful of rye is found in his jacket. Nobody seems too upset, as Rex was universally disliked as a tyrant, especially by his children.
Inspector Neele (McFadyen) is despatched to the house to investigate. Maid Gladys who was trained by Miss Marple, is acting strangely, and writes to her former employer for help. Yet the call for help has come too late: Rex's glamorous and cheating young wife also falls foul of the poisoner. And Gladys is found strangled, a peg on her nose.
The case appears to be echoing the children's rhyme 'Sing A Song of Sixpence'. The question is: who will be next?
Graves and McFadyen appeared together in last year's Death at the Funeral, (along with Keeley Hawes from Ashes to Ashes):
