From BBC Radio 4 Extra. Written by Agatha Christie; Full-cast dramatisation starring John Moffatt as Hercule Poirot, with George Baker as Superintendent Spence, and Julia McKenzie as Ariadne Oliver.

The gruesome death of Mrs McGinty provokes Superintendent Spence to seek the help of his old ally Hercule Poirot. The victim's young lodger has been found guilty and is due to hang. But, Spence is not convinced by the circumstantial evidence which influenced the verdict. So, at considerable personal discomfort, Poirot goes down to the sleepy village where the old lady lived and where, by chance, his good friend Ariadne Oliver is also staying. There, he alights upon his first and most crucial clue - a newspaper article on the present whereabouts of women implicated in notorious murder cases. Did Mrs McGinty have to die because she had identified one of her neighbours as a brutal killer? Is that killer still at large, and can Poirot and Ariadne act swiftly enough to save an innocent man from the gallows?
