According to BBC News the remaining five books of Agatha's Christie's famous Belgian detective will be adapted to the small screen. The Labours of Hercules, The Big Four, Dead Man's Folly, Elephants Can Remember, and the last novel, Curtain.

Shooting begins this October until July 2013...
What a challenging final five to adapt. The Big Four is a James Bond-esque caper during Hercule Poirot's prime, and Curtain features the elderly detective during his last great mystery.  If they decide to stay true to the novels, we shall see some of our favourite characters return, including Miss Lemon, Hastings, Inspector Japp, and Ariadne Oliver.  I can't wait.
