A collection of thrilling tales from the Golden Age of Detective Fiction, including six full-cast dramas and a short story read by Benedict Cumberbatch

In the first half of the 20th century, the detective story exploded in popularity. Innovative authors penned whodunits, whydunits and clue-puzzle stories, and introduced iconic sleuths, creating works that would later become classics. This Golden Age, which reached its height during the 1920s and ’30s, saw the crowning of the ‘Queens of Crime’, the formation of the Detection Club and the laying down of new rules of crime writing – and the fiction produced during this period has had lasting appeal and influence, fundamentally shaping the ‘cosy crime’ novels of today.

This collection gathers together seven sensational stories from Golden Age authors – some well-known, others unjustly overlooked – beginning with three by founding members of the Detection Club. The Blue Cross by G.K. Chesterton features the first appearance of one of the best-loved detectives in fiction: Father Brown, as he pursues arch-villain and master of disguise Flambeau. Andrew Sachs stars as the insightful cleric, with Olivier Pierre as his wily nemesis.

In The House of the Arrow by A.E.W. Mason, starring Richard Pasco and Moir Leslie, a young woman living in Dijon is accused of murder, leading her lawyer to call in the Sûreté’s best officer, Inspector Hanaud.

Narrated by Benedict Cumberbatch, The Affair of the German Dispatch-Box by Victor Whitechurch sees daring Edwardian sleuth Thorpe Hazell using his locomotive expertise to solve an ingenious and audacious railway crime.

A legendary assassin and vigilante returns from the dead in The Ringer by Edgar Wallace, and Scotland Yard must find him before he exacts his revenge. David Davis stars as the ‘Gaunt Stranger’, and Alexander John as the tenacious Inspector Wembury.

In An Unrecorded Instance by Marie Belloc Lowndes, Hetty Mingle ignores her dying mother's advice about fortune hunters – but will she end up regretting it? Starring Mary O’Farrell and Brenda Bruce.

The Golden Slipper by Anna Katharine Green finds New York debutante (and reluctant detective) Violet Strange tasked with investigating four rich young women suspected of multiple thefts. Teresa Gallagher stars as the socialite sleuth, with Crawford Logan as her client, Driscoll.

Concluding this collection is Miss Pym Disposes by Josephine Tey, which finds psychologist Lucy Pym investigating a death at a women’s physical education college. Starring Julia Foster as Miss Pym and Joan Sims as her friend, headmistress Henrietta Hodge, this dark, engrossing psychological thriller is a late Golden Age gem.
