Well, it's no wonder. The plot - suspicion for an elderly woman's murder falls on her mysterious lodger - is from Agatha Christie. The wonderful character happens to be the world's most famous sleuth, Hercule Poirot.

Agatha Christie wrote The Mysterious Affair at Styles during the midst of World War I. The book was published in 1920 and became extremely popular because of the well-grounded plot and interesting characters. The novel is set at Styles Court, a wealthy estate in England during the war. The estate's owner, Mrs. Cavendish, had inherited the estate as well as vast sums of money from her late husband.

An urgent cry for help brings Poirot to France. But he arrives too late to save his client, whose brutally stabbed body now lies face downwards in a shallow grave on a golf course. But why is the dead man wearing his son's overcoat? And who was the impassioned love-letter in the pocket for? Before Poirot can answer these questions, the case is turned upside down by the discovery of a second, identically murdered corpse....

"The Ravenscrofts didn't seem that kind of person. They seemed well balanced and placid..." And yet, twelve years earlier, the husband had shot the wife, and then himself - or perhaps it was the other way around, since sets of both of their fingerprints were on the gun, and the gun had fallen between them. The case haunts Ariadne Oliver, who had been a friend of the couple. The famous mystery novelist desires this real-life mystery solved, and calls upon Hercule Poirot to help her do so.

Sir Charles Cartwright should have known better than to allow 13 guests to sit down for dinner. For at the end of the evening one of them is dead - choked by a cocktail that contained no trace of poison. Predictable, says Hercule Poirot, the great detective. But entirely unpredictable is that he can find absolutely no motive for murder.…

Whilst organising a mock murder hunt for the village fete hosted by Sir George and Lady Stubbs, a feeling of dread settles on the famous crime novelist Adriane Oliver. Call it instinct, but it's a feeling she just can't explain...or get away from.

What is the connection among a failed suicide attempt, a wrongful accusation of theft against a schoolgirl, and the romantic life of a famous tennis player?

As Superintendent Battle discovers, it is all part of a carefully laid plan - for murder.

Mrs Packington felt alone, helpless, and utterly forlorn. But her life changed when she stumbled upon an advertisement in The Times/i> which read: "ARE YOU HAPPY? IF NOT, CONSULT MR PARKER PYNE". Equally adept at putting together the pieces of a marriage or the fragments of a murder mystery, Mr Parker Pyne was possibly the world's most unconventional private eye, and certainly its most charming.

In appearance Hercule Poirot hardly resembled an ancient Greek hero. Yet, reasoned the detective, like Hercules, he had been responsible for ridding society of some of its most unpleasant monsters. So, in the period leading up to his retirement, Poirot makes up his mind to accept just 12 more cases: his self-imposed "Labors". Each would go down in the annals of crime as a heroic feat of deduction.
