All Will Be Revealed Trivia Quiz

Answer: The Adventure of the Clapham Cook

This was the first episode aired, in 1989. Poirot's investigations quickly led him to the missing cook, Eliza Dunn, who had been told that she had inherited a nice property, on the condition that she leave service immediately. She promptly packed her things and left, moving to the house she had ostensibly inherited, according to the 'lawyer' who approached her in the street.

She was surprised when her belongings arrived wrapped in brown paper instead of being in her trunk, but wrote it off to spitefulness on the part of her ex-employer. Poirot, however, saw the significance of the ruse to obtain her trunk for nefarious purposes. Arthur Simpson, a lodger at the place of her previous employment, was a clerk in the same bank as Davis, the missing bank clerk whose disappearance Poirot had not found interesting enough to investigate. Simpson had murdered Davis and taken possession of the stolen securities.

He disguised himself and pretended to be a lawyer in order to get Eliza to send her trunk to a place from which he could retrieve it and use it to conceal the body. Due to Poirot's quick mind, his scheme was foiled.

Answer: The Disappearance of Mr Davenheim

This was the fifth episode in season two, originally aired in 1990. Matthew Davenheim told his wife he was going to post a letter, shortly before the expected arrival of a South African business associate named Lowen. When he did not return, the police were called in, and Mrs Davenheim discovered that her jewels were missing from their safe, along with a significant amount of cash and securities. Billy Kellett, who had spent three months the previous year in jail after being convicted as a pickpocket, stated that he had seen Lowen throw Davenheim's distinctive ring away. Kellett retrieved the ring, pawned it, and got himself arrested for drunk and disorderly conduct after drinking the proceeds.

The police arrested Lowen, but Poirot was able to deduce that Kellett was actually Davenheim, who had set up this alternative identity the previous year, when he had supposedly been in South Africa on business.

He had long-term plans for a new life, running out to avoid the imminent collapse of his bank, but they came to nought thanks to Poirot.

Answer: How Does Your Garden Grow

This first episode of series three originally aired in 1991. In the early part of the episode, Miss Lemon explained to Poirot that one should never pay cash to a shopkeeper, as they will remember you. That proved to be the downfall of the Delafontaines, as Miss Lemon had no difficulty locating the fishmonger who had sold Mrs Delafontaine the oysters on which they placed the strychnine with which her aunt was poisoned. Since she had been forbidden oysters by her doctor, she was eager for the illicit treat, and devoured them all. Mrs Delafontaine disposed of the oyster shells by adding them as a decorative element edging the garden beds. Poirot noticed them because of their asymmetry - twelve oysters weren't enough to make a complete edging in an otherwise neatly ordered garden that met with his highest approval.

Answer: Death in the Clouds

This feature-length episode was the second one aired in the fourth season of the show, in 1992. The original suspect was a wasp that had been flying around the cabin, but Poirot quickly established that as a red herring. The realization that a poison dart had been used, however, led to much speculation as to what could have been used as a blow-pipe to send it through the air, and how that could have been accomplished without attracting notice.

The Countess of Horbury became a prime suspect, followed by her maid, Anne Morisot, who turned out to be Madame Giselle's heir, giving her a prime motive for the crime.

However, her subsequent death after the plane had landed suggested to Poirot that she was actually another victim. Investigation revealed that Norman Gale had recently married her, and Poirot was able to reveal him as the murderer.

There was no blowpipe at all - he walked past them all holding the dart in his hand, and stabbed Madame Giselle with it. This ruse of avoiding being observed in the act of murder because one is dressed as a servant was used again in 'Yellow Iris'.

Answer: The Adventure of the Italian Nobleman

Miss Lemon had indeed been dating Graves in the fifth episode of season five, originally aired in 1993, but she was led to believe that he was a nobleman, not a valet (and certainly not a murderer). Poirot initially noted that the curtains had not been drawn, which any decent valet would have done if he actually left after dark. Taken in conjunction with the fact that all three main dishes had been eaten, but little of the side dishes and virtually none of the dessert, Poirot deduced that Graves had killed Foscatini earlier (to steal the blackmail money delivered the previous day by Ascanio), and attempted to eat three dinners to make it seem as if the crime had happened much later. Forensic evidence investigation clearly wasn't what it is today!

Answer: Evil Under the Sun

In this first episode of series eight, originally aired in 2001, Patrick and Christine created a number of illusions as they attempted to fleece Arlena, then killed her to avoid discovery. Patrick's infatuation was no more real than his wife's outrage, and they exploited the very real emotions of those around them to obfuscate their actions. Patrick arranged to meet Arlena on the beach of a deserted cove, but at a slightly later time than the moment when he and Emily rowed around the point and saw 'Arlena' on the beach, tanned arms outstretched and face hidden by the large hat she affected. Patrick went ashore, pretended to have discovered that she was dead, and sent Emily for help. Christine then ran back to the hotel and washed off the fake tan, while Patrick met and strangled the real Arlena. Poirot untangled the intricate time alibis, and the murderer was revealed.

Answer: Murder in Mesopotamia

This was the second of two episodes in season eight, originally released in 2001, but not aired in the UK until 2002. As Poirot discovered, Frederick Bosner, who had been convicted of spying for Germany during World War I, did not die in the train accident when he supposedly lost his life. Rather, he assumed the identity of a fellow passenger who had died, Erich Leidner. Years later he remarried his wife, who did not recognize him.

When he realized that she was becoming interested in another man, he tried to scare her into faithfulness with ghostly effects and threatening letters, but eventually decided she had to die so that no other could have her. Poirot, of course, worked out how this was accomplished, and simultaneously explained some of the mysterious events at the dig as being related to artifact theft by an international thief who had replaced the ill Father Lavigny in order to establish himself on site.

Answer: Death on the Nile

You would think that people would know better than to try and blackmail people they know to be quite capable of murder to gain their desired goals, but then so many of Agatha Christie's plots would lack a suitable twist. 'Death on the Nile', the third episode of series nine, originally aired in 2004. To divert suspicion, Jackie pretended to shoot Simon, who created the appearance of a wound using red ink.

While one witness ran to fetch a doctor, and one took Jackie to be confined in her cabin, Simon took the gun to Linnet's cabin where he shot her, before returning to the lounge and actually shooting himself.

When the doctor arrived, he was able to confirm that, with the wound Simon currently bore, he could not possibly have moved fast enough to have committed the murder. Leave it to Poirot to notice the nail polish! As well as solving Linnet's murder, Poirot uncovered an embezzling lawyer (Andrew Pennington), a jewel thief (Tim Allerton) and a secret alcoholic (Salome Otterbourne).

Answer: Cards on the Table

In the second episode of series ten, originally released in 2005, Mr Shaitana assembled an intriguing mixture of detectives and people who, according to Shaitana, had gotten away with murder. Investigating the pasts of the other guests led Poirot to the conclusion that each was, in fact, quite possibly guilty of an unprovable previous crime. Each of them, therefore, had a motive, but Poirot discovered the opportunity by considering the psychology of the players.

The excitement of playing a difficult grand slam (overbid by Dr Roberts to establish the tense situation) would have kept the other three players occupied, making it easy for the dummy to slip away and commit murder. Since Dr Roberts was the dummy, he was revealed as the murderer. And, of course, the reckless action despite (perhaps because of) its danger was right in line with the psychology that the players' bidding and play had revealed to Poirot!

Answer: Murder on the Orient Express

In the fourth episode of series twelve, originally aired in 2010, Poirot found himself on board the Orient Express when it became stuck in a snowstorm, and the unsavoury American was discovered dead, stabbed to death in his sleeping compartment. Poirot needed to discover the murderer before the train was free to move, and escape would be possible.

In one of Agatha Christie's most well-known surprise endings, Poirot revealed that Ratchett was actually a fugitive named Cassetti, who had kidnapped and killed young Daisy Armstrong despite the payment of a large ransom. All the other passengers had been deeply wounded by the event and/or its aftermath, and had come together to act as a twelve-person jury to execute judgment on the man who had been the cause of their suffering.

As Poirot explained, only this could explain the maze of conflicting clues that he had found. Or it might have been some unknown enemy who had secretly boarded the train, committed the murder, then escaped through the snow.
