Agatha Christie's Poirot

 Helen Baxendale will be playing Elizabeth Cole in the last ever episode of Agatha Christie's Poirot.

Crippled with arthritis, Poirot is now using a wheelchair and has a life-threatening heart condition, but remains as sharp as ever. Calling on old friend Captain Hastings for assistance, he returns to Styles, where the pair first met 30 years earlier on a murder investigation.

Agatha Christie's Poirot can be seen tonight at 8pm on ITV1.
