Cantankerous and dishevelled, Chief Inspector Dover is no one's idea of a model detective - but he does have an uncanny knack for solving crimes. In these radio dramas, set in the 1960s and '70s, he and his long-suffering sergeant, Charlie McGregor, investigate sinister cases of kidnap and murder. The first four are adapted from Joyce Porter's novels, while the latter two are original stories based on her characters.

With his cape, canes and shovel hat, portly amateur sleuth Dr Gideon Fell cuts an eccentric figure - but his odd appearance belies his sharp intellect and astonishing faculty for deduction.

This radio collection comprises all eight of the BBC adaptations based on Carr's best-selling books.

Brighton, 1957: a sunny seaside resort with a sinister underbelly. This den of villainy is policed by the touchingly innocent Inspector Steine, who naively believes he wiped out all the hoodlums in the Middle Street Massacre six years earlier.

Wilkie Collins was one of Victorian England's best-loved and best-selling authors, and a crime-fiction pioneer. His enthralling 'sensation novels' such as The Woman in White paved the way for today's thrillers and his tour de force The Moonstone is one of the first, and greatest, modern-detective stories. This collection features dramatisations of these two masterpieces, with star casts including Toby Stephens (The Woman in White) and John Sharp (The Moonstone). Also included are adaptations of three of Collins' other major novels.

The dapper, mustache-twirling little Belgian with the egg-shaped head and curious mannerisms has solved some of the most puzzling crimes of the century - and, in his own humble opinion, is "probably the greatest detective in the world". In this complete collection of more than 50 stories, ranging from short tales to novellas, Poirot faces violent murders, poisonings, kidnappings, and thefts - all solved with his characteristic panache. Only Agatha Christie could have devised cases worthy of Hercule Poirot's skill and "little gray cells". 

In the respectable seaside town of Flaxborough, the equally respectable councillor Harold Carobleat is laid to rest. Cause of death: pneumonia. But he is scarcely cold in his coffin before Detective Inspector Purbright, affable and annoyingly polite, must turn out again to examine the death of Carobleat's neighbour, Marcus Gwill, former prop. of the local rag, the Citizen. This time it looks like foul play, unless a surfeit of marshmallows had led the late and rather unlamented Mr Gwill to commit suicide by electrocution. ('Power without responsibility', murmurs Purbright.)  

With his black hat, huge umbrella, unworldly simplicity and 'beaming but breathless geniality', Father Brown is one of fiction's best-loved amateur detectives.

Locked down with his semi-detached wife, Frances, Charles has thrown himself into a new career as a handyman, becoming quite the DIY expert.

The star, Justin Grover, asked for him specifically, but Charles has reservations. Grover was cocky enough when they were both young hopefuls; now, he's the star of a massive TV fantasy series, and the play - a verbatim piece set in a monastery - is dire.
