Mystery of the Skeleton Key

If Hugh had returned from hunting by another path, or if he had left his gun behind him, or if one could have told just when the shot was heard, perhaps the murder of beautiful Annie Evans might have been cleared up without so much effort on the part of the famous Sergeant Ridgeway from Scotland Yard, or so much mutual suspicion on the part of the various guests assembled at the Hall. Baron Le Sage of doubtful fame might have gone on playing chess, and pretty Audrey's love affairs might not have become so tangled. But it's just as well as it is, perhaps, for the result of all these complications is a thoroughly exciting detective story.
