Who? When? How? Why? This series immerses us in the chaos at the dark heart of crime fiction, taking us on journey through the labyrinthine workings of the whodunnit, with many a shudder along the way. Nowadays, one published novel in four is a "roman noir", a "thriller" or a "detective story". How did crime fiction come to be so popular that it is now a universal language everyone can understand? Through interviews with present-day creators of crime fiction, this series analyses the fateful trio of the victim, the murderer and the detective, piecing together a profile of emblematic figures who provide the starting-point for all good whodunnits, and explore locations and plots.
