A BBC Radio 4 full-cast dramatisation starring John Moffatt as Hercule Poirot with Stephanie Cole and Donald Sinden. Hercule Poirot, along with three other luminaries from the world of crime detection, is invited to dinner by the renowned London socialite Dr Shaitana. Also on the guest list are four members of what Shaitana calls his Black Museum - a collection of murderers who have each succeeded in 'getting away with it'. After midnight, when the guests prepare to leave, they make a terrible discovery.

"Anyone who murdered Colonel Protheroe," declared the parson, "would be doing the world at large a service!" 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. From seven potential murderers, Miss Marple must seek out the suspect who has both motive and opportunity.

Luke Fitzwilliam could not believe Miss Pinkerton's wild allegation that a multiple murderer was at work in the quiet English village of Wychwood, or her speculation that the local doctor was next in line. But, within hours, Miss Pinkerton had been killed in a hit-and-run car accident. Mere coincidence? Luke was inclined to think so, until he read in The Times of the unexpected demise of Dr Humbleby.

After the death of her husband, Dolly Bantry sold Gossington Hall to the former film star Marina Gregg and her husband.

As Marina is serving cocktails in the house, she is cornered by the excitable Heather Babcock, who chatters away about their former meeting about eleven years ago before spilling her daiquiri all over herself and Marina.

From seat No.9, Hercule Poirot was ideally placed to observe his fellow air passengers. Over to his right sat a pretty young woman, ahead, across the gangway in seat No.8, a detective writer was being troubled by an aggressive wasp. What Poirot did not yet realize was that behind him, in seat No.2, sat the slumped, lifeless body of a woman.

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.

Miss Marple, Agatha Christie’s deceptively mild spinster sleuth, is being treated to a few days’ holiday by her niece, staying at Bertram’s Hotel, a dignified, unostentatious establishment tucked away in a back street of busy Mayfair. Here is a place where sedate upper class ladies, retired military gentlemen and the higher echelons of the clergy can indulge in the comforts of a bygone age. But Miss Marple begins to feel uneasy. Something sinister lurks beneath the polished veneer.

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.

It's seven in the morning. The Bantrys wake to find the body of a young woman in their library. She is wearing evening dress and heavy make-up, which is now smeared across her cheeks. But who is she?

A triple bill of archive BBC radio dramas, believed lost for over half a century and only recently rediscovered. "Butter in a Lordly Dish", written specially for radio in 1948, features Richard Williams as Sir Luke Enderby KC, whose infidelities lead him into trouble when he goes to meet his latest flame. Williams also stars as Hercule Poirot in "Murder in the Mews", a 1955 adaptation of a short story. A young woman is found dead in her flat the day after Guy Fawkes night.

Trying to solve these 13 mysteries are Raymond West, a young writer; the artist Joyce Lemprière; Dr Pender, the clergyman, who claims to know the hidden side of human character; Mr Petherick, a lawyer who is only interested in the logical approach; and Sir Henry Clithering, whose experience as commissioner of Scotland Yard speaks for itself.
