Carolyn Wells 
In the Onyx Lobby 

‚Well, by the Great Catamaran! I think it’s the most footle business I ever heard of! A regulation, clinker-built, angle-iron, sunk-hinge family feud, carried on by two women! Women! conducting a feud! They might as well conduct a bakery!‘ Carolyn Wells is regarded as one of the most influential writers of the Golden Age of mystery novels; she even penned a well-known book on mystery writing techniques. Her unparalleled skill at crafting airtight plots is on full display in In the Onyx Lobby, which recounts the investigation into what seems to be the perfect crime.
