Beautiful young Elinor Carlisle stands serenely in the dock, accused of the murder of Mary Gerrard, her rival in love. The evidence is damning: only Elinor had the motive, the opportunity, and the means to administer the fatal poison. Yet, inside the hostile courtroom, one man still presumes Elinor is innocent until proven guilty: Hercule Poirot, who is all that stands between Elinor and the gallows.

Mrs McGinty died from a brutal blow to the back of her head. Suspicion fell immediately on her shifty lodger, James Bentley, whose clothes revealed traces of the victim's blood and hair. Yet something was amiss: Bentley just didn't look like a murderer.

It was not unusual to find the beautiful bronzed body of the sun-loving Arlena Stuart stretched out on a beach, face down. Only, on this occasion, there was no sun...she had been strangled. Ever since Arlena's arrival at the resort, Hercule Poirot had detected sexual tension in the seaside air. But could this apparent 'crime of passion' have been something more evil and premeditated altogether?

An outbreak of kleptomania at a student hostel was not normally the sort of crime that aroused Hercule Poirot's interest. But then he saw the list of stolen and vandalized items: a stethoscope, some old flannel trousers, a box of chocolates, a slashed rucksack, and a diamond ring found in a bowl of soup. The list made absolutely no sense at all. But, reasoned Poirot, if this was merely a petty thief at work, why was everyone at the hostel so frightened?

Lucy Angkatell invited Hercule Poirot to lunch. To tease the great detective, her guests stage a mock murder beside the swimming pool. Unfortunately, the victim plays the scene for real. As his blood drips into the water, John Christow gasps one final word: "Henrietta". In the confusion, a gun sinks to the bottom of the pool. Poirot's enquiries reveal a complex web of romantic attachments. It seems everyone in the drama is a suspect, and each a victim of love.

Hercule Poirot stood on the cliff-top. For here, many years earlier, there had been a tragic accident: the broken body of a woman was discovered on the rocks at the foot of the cliff. This was followed by the grisly discovery of two more bodies, a husband and wife, shot dead. But who had killed whom? Was it a suicide pact? A crime of passion? Or cold-blooded murder?

The house guests at Styles seemed perfectly pleasant to Captain Hastings. There was his own daughter, Judith; an inoffensive ornithologist called Norton; dashing Mr Allerton; brittle Miss Cole; Doctor Franklin and his fragile wife, Barbara; Nurse Craven; Colonel Luttrell and his charming wife, Daisy; and the charismatic Boyd-Carrington. So Hastings was shocked to learn from Hercule Poirot's declaration that one of them was a five-times murderer.

A classic Christie mystery. Read by Hugh Fraser who plays Hugh Fraser in the popular TV series. At a Hallowe’en party, Joyce – a hostile thirteen-year-old – boasts that she once witnessed a murder. When no-one believes her, she storms off home. But within hours her body is found, still in the house, drowned in an apple-bobbing tub. That night, Hercule Poirot is called in to find the ‘evil presence’. But first he must establish whether he is looking for a murderer or a double-murderer…

The dentist was found with a blackened hole below his right temple. A pistol lay on the floor near his out-flung right hand. Later, one of his patients was found dead from a lethal dose of local anaesthetic. It's a clear case of murder and suicide. But why would a dentist commit a crime in the middle of a busy day of appointments? A shoe buckle holds the key to the mystery. Now, in the words of the rhyme, can Poirot pick up the sticks and lay them straight?

As instructed, stenographer Sheila Webb let herself into the house at 19 Wilbraham Crescent. It was then that she made a grisly discovery: the body of a dead man sprawled across the living-room floor. What intrigued Poirot about the case was the time factor. Although in a state of shock, Sheila clearly remembered having heard a cuckoo clock strike 3.00. Yet, the four other clocks in the living room all showed the time as 4.13. Even more strange: only one of these clocks belonged to the owner of the house.

A few weeks after marrying an attractive young widow, Gordon Cloade is tragically killed by a bomb blast in the London blitz. Overnight, the former Mrs Underhay finds herself in sole possession of the Cloade family fortune. Shortly afterwards, Hercule Poirot receives a visit from the dead man's sister-in-law, who claims she has been warned by "spirits" that Mrs Underhay's first husband is still alive.

Mr Shaitana was famous as a flamboyant party host. Nevertheless, he was a man of whom everybody was a little afraid. So, when he boasted to Poirot that he considered murder an art form, the detective had some reservations about accepting a party invitation to view Shaitana's private collection.

How did a woman holding a pistol in her right hand manage to shoot herself in the left temple? What was the link between a ghost sighting and the disappearance of top secert military plans? How did the bullet that killed Sir Gervase shatter a mirror in another part of the room? And who destroyed the "eternal triangle" of love involving renowned beauty, Valentine Chantry?

Thirteen guests arrived at dinner at the actor's house. It was to be a particularly unlucky evening for the mild-mannered Reverend Stephen Babbington, who choked on his cocktail, went into convulsions and died. But when his martini glass was sent for chemical analysis, there was no trace of poison, just as Poirot had predicted. Even more troubling for the great detective, there was absolutely no motive.

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 made up his mind to accept just 12 more cases: his self-imposed "labours". Each would go down in the annals of crime as a heroic feat of deduction.
