The Last Poirot Short Story

Four and 20 Blackbirds is the final Poirot short story ever to be published. It was collected in The Adventure of the Christmas Pudding and a selection of entrees, which was published by Collins Crime Club in 1960. Agatha Christie apparently had first sketched out this story for Parker Pine, not our dear Poirot. And yes, if you picked up on that rather loose and weak pun of hasty pudding there, please know it was very much intended.
