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.

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.

Mr. Shaitana is famous as a flamboyant party host. Nevertheless, he is a man of whom everybody is a little afraid. So when he boasts to Hercule Poirot that he considers murder an art form, the detective has some reservations about accepting a party invitation to view Shaitana's "private collection". Indeed, what begins as an absorbing evening of bridge is to turn into a more dangerous game altogether.

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.…

Miss Emily was old, rich, and afraid - and now, she's dead. Her terrified plea to Hercule Poirot came a little too late. All that's left is a house full of greedy heirs, and a very strange letter that could solve the mystery - or add to it.

A far-from-warm welcome greets Hercule Poirot as he arrives for lunch at Lucy Angkatell's country house. A man lies dying by the swimming pool, his blood dripping into the water. His wife stands over him, holding a revolver. As Poirot investigates, he begins to realize that beneath the respectable surface lies a tangle of family secrets and everyone becomes a suspect.

Roger Ackroyd knew too much. He knew that the woman he loved had poisoned her brutal first husband. He suspected, also, that someone had been blackmailing her. Then, tragically, came the news that she had taken her own life with a drug overdose. But the evening post brought Roger one last fatal scrap of information. Unfortunately, before he could finish reading the letter, he was stabbed to death.

Beautiful Caroline Crale was convicted of poisoning her husband, but just like the nursery rhyme, there were five other "little pigs" who could have done it: Philip Blake (the stockbroker), who went to market; Meredith Blake (the amateur herbalist), who stayed at home; Elsa Greer (the three-time divorcee), who had her roast beef; Cecilia Williams (the devoted governess), who had none; and Angela Warren (the disfigured sister), who cried all the way home.

Sixteen years later, Caroline's daughter is determined to prove her mother's innocence.

When Cora Lansquenet is savagely murdered with a hatchet, the extraordinary remark she made the previous day at her brother Richard's funeral suddenly takes on a chilling significance. At the reading of Richard's will, Cora was clearly heard to say, "It's been hushed up very nicely, hasn't it.... But he was murdered, wasn't he?"

In desperation, the family solicitor turns to Hercule Poirot to unravel the mystery....

The beautiful bronzed body of Arlena Stuart lay face down on the beach. But strangely, there was no sun and Arlena was not sunbathing - she had been strangled.

Ever since Arlena's arrival the air had been thick with sexual tension. Each of the guests had a motive to kill her, including Arlena's new husband. But Hercule Poirot suspects that this apparent "crime of passion" conceals something much more evil.

First there was the mystery of the film star and the diamond...then came the "suicide" that was murder...the mystery of the absurdly cheap flat...a suspicious death in a locked gun room...a million-dollar bond robbery...the curse of a pharaoh's tomb...a jewel robbery by the sea...the abduction of a prime minister...the disappearance of a banker...a phone call from a dying man...and finally, the mystery of the missing will. What links these fascinating cases? Only the brilliant deductive powers of Hercule Poirot!

Rex Fortescue, king of a financial empire, was sipping tea in his "counting house" when he suffered an agonizing and sudden death. On later inspection, the pockets of the deceased were found to contain traces of cereals. Yet, it was the incident in the parlor that confirmed Miss Marple's suspicion that here she was looking at a case of crime by rhyme....

"Anyone who murdered Colonel Protheroe," declared the parson, brandishing a carving knife above a joint of roast beef, "would be doing the world at large a favor!" It was a careless remark for a man of the cloth. And one which was to come back and haunt the clergyman just a few hours later - when the Colonel is found shot dead in the clergyman's study. But as Miss Marple soon discovers, the whole village seems to have had a motive to kill Colonel Protheroe.

Christmas Eve, and the Lee family's reunion is shattered by a deafening crash of furniture and a high-pitched wailing scream. Upstairs, the tyrannical Simeon Lee lies dead in a pool of blood, his throat slashed. When Hercule Poirot offers to assist, he finds an atmosphere not of mourning but of mutual suspicion. It seems everyone had their own reason to hate the old man....

"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.
