Ariadne Oliver, attending the Halloween party while visiting her friend Judith Butle. The party held at Rowena Drake's home in Woodleigh Common. For Ariadne, this is going to be horrible party ever, because there was the murder happened. The victim named Joyce, thirteen-year-old tells everyone attending she had once seen a murder, but had not realised it was one until later. When the party ends, Joyce is found dead, having been drowned in an apple-bobbing tub. Immediately, Ariadne called out to her friend, the famous detective, Hercule Poirot to investigate the murder and Joyce's claim.
‘We go from the past to the future,’ said Poirot.
So, Poirot had to investigate a case in the past that might not even have happened, and was just a teenage braggart. As many Woodleigh Commons say, Joyce was a kid who wanted attention, and wanted to look cool in the eyes of Ariadne Oliver, the mystery writer. with the help of his friend, from retired Superintendent Spence, Poirot begins to investigate cases that occurred in the past, in which at this time it was most likely that the perpetrators had not yet been brought to justice or were found innocent when tried.
