How Does Your Garden Grow? (S03E02)

When elderly Amelia Barrowby is poisoned in her home the obvious culprit seems to be her companion Katrina. Poirot and Hastings had met Amelia at the Chelsea Flower Show earlier that summer where a rose had been named after the great detective. Poirot hurries to Ameila's home where his new found interest in gardening pays off when he spots something fishy in Amelia's garden border. (iTunes)
