When we reach 221B Baker Street, Watson greets us. "Holmes is abuzz this morning, he’s waiting in the lounge." "Ah, there you are at last gentlemen, have you read the paper?" We shake our heads. "Direct your attentions to the article 'Mysterious death at the embassy.'" Holmes pauses while we read... So begins "The Diavolo Case," Yann Gentil's second extra-case expansion for Sherlock Holmes Consulting Detective. Available for download on the author's website (in French).
