Murder! When the Count de Roscanvel's body is found on the railway tracks, shot through the heart then hit by the Blue Train from Paris to Marseille, police charge France's top young novelist with his killing, and the Count's beautiful wife is suspected of complicity. Harrassed by the police and shunned by her family, there's only place Countess de Roscanvel can turn. A small house in Paris on Avenue de Verzy, home to... Chantecoq. King of detectives, master of disguise. With the help of his secretary Météor, daughter Colette, and star reporter son-in-law Jacques Bellegarde, Chantecoq finds himself caught up in a race against time to save an innocent man, and to restore the Countess' honour. As an enigmatic former client returns to haunt France's greatest detective, and a masked man stalks the Countess de Roscanvel, can Chantecoq solve the Mystery of the Blue Train? First published in France in 1929 (as "Le Mystère du Train Bleu""), and never before translated into English, this book is part of the "Further Exploits of Chantecoq" series, which sees the secret agent and expert spy catcher of Chantecoq and the Aubry Affair reborn as the greatest private detective of his age.
