This part of Dava Sobel's book, #Longitude stuck in my mind for years. I forgot the vengeful end of Clowdisley Shovell's life though:
> .. a local woman combing the beach purportedly found his body and fell in love with the emerald ring on his finger. Between her desire and his depletion, she handily murdered him for it. Three decades later, on her deathbed, this same woman confessed the crime to her clergyman, producing the ring as proof of her guilt and contrition.
