On a winter evening in bad weather, Matthew, Earl of Whittingham, arrives at Leighton House, having traveled a long way from London at the invitation of a respected scientist. He wanted to have a personal conversation with a colleague and hear how he could explain a recent article published in a journal that had stirred up the scientific community.But at the estate, Matthew meets the beautiful Theodosia Layton — the lady was raised by her grandfather, a scientist, and lived with him all her life in the countryside, devoting her life to books and scientific experiments. It was she who sent the article to the magazine, signing her grandfather's name, and now she regrets it. Matthew quickly exposes the girl — and soon realizes that he is very interested in her.
