Halloween’s as much about guilty little treats as it is about undead souls. This Halloweens treat is a special episode of Agatha Christie’s Poirot. Possibly the most dark and sinister Poirot yet starts out with a children’s Halloween party complete with witches, eerie music, jack o lanterns, fire a haunting game of snap dragon and of course a death. Add into the mix a cast of suspicious characters and an un co-operative police officer in a rural setting and you tada, one classic who dunnit.

Award winning actress Zoë Wanamaker makes a welcome return, alongside David Suchet, as Ariadne Oliver in Hallowe’en Party.

Adapted by actor, screenwriter and novelist, Mark Gatiss, Hallowe’en Party also stars Amelia Bullmore, Deborah Findlay , Georgia King, Julian Rhind-Tutt, Sophie Thompson, Paul Thornley, Eric Sykes, Fenella Woolgar and Timothy West.

When Ariadne Oliver attends a children’s Hallow e’en party in Woodleigh Common with her friend Judith, a young girl boasts of having witnessed a murder years before. Later that evening, the girl, Joyce Reynolds is found dead, drowned in an apple-bobbing bucket in the library. It appears that any one of the guests could have slipped out in the dark during a game of Snapdragon and murdered her.

At the request of Ariadne, Hercule Poirot arrives at Woodleigh Common to investigate the murder. Though Joyce was dismissed as a fantasist, Poirot is convinced her story has some truth to it. When he seeks out the local gossip, he discovers that there have been a number of suspicious deaths in the village in recent years which Joyce could have witnessed. But while Poirot pieces together the facts, another child is found murdered. Could a forged codicil, a missing au pair and a secret love affair be the key to solving the crime?

Watch the Poirot Halloween Special in ITV1 at 8pm on Wednesday 27th October.
