About this production
First published in 1928, The Mystery of the Blue Train sends Hercule Poirot down to the French Riviera aboard Le Train Bleu, the luxury night express from Calais to Nice. When the wealthy Ruth Kettering is found dead in her compartment and the fabled ruby known as the "Heart of Fire" vanishes, a carriage full of strangers — an estranged husband, a maid, a dancer, a quiet Englishwoman named Katherine Grey — each become suspects. It is Christie at her most cinematic: a closed world in motion, a cast of secrets, and a detective who trusts order and method over instinct.
That contained setting is exactly what makes the novel suit a dramatized treatment. A train is a natural sound stage — the rhythm of the rails, the hush of a sleeping car, the clipped exchanges between passengers who would rather not be overheard. In the Midsummerr production, every character carries a distinct AI-generated voice, so the interrogations play as real conversation rather than a single narrator reporting dialogue. Poirot's precision, the glamour of the Riviera, and the menace beneath the surface each get their own register.
Underneath the performances runs an original score and cinematic sound design that place you in 1920s Europe — the station platforms, the dining car, the slow build of suspicion toward the reveal. The full production spans 38 chapters and roughly 8h 45m, free to listen from start to finish.
