The 1920s had a lot of great literature. While there may not be a novel that directly has 'bride's house' in the title, Zelda Fitzgerald's writings could be relevant. She was part of the literary scene of the 1920s. Her works, along with her husband F. Scott Fitzgerald's, often dealt with the glamorous and sometimes tumultuous lives of the upper class. There could be situations in their stories where a bride would be in a grand house, even if not the main focus.
One such novel could be 'The Great Gatsby'. Although not directly centered on a bride's house, it portrays the lavish lifestyle of the 1920s which might include grand houses where brides could potentially live. Another might be novels by Edith Wharton. Her works often explored the upper - class society of the time and the settings of their homes, which could be relevant to the idea of a bride's house.
Father Brown was a fantasy novel written by the world's tyrant singer. Currently, the original authorized publishing house of the novel was Reader's Press.
The origin story behind the 'You killed my father' line in 'The Princess Bride' is quite interesting. The movie is full of political intrigue and power plays. It could be that the person accused of killing the father was involved in a scheme to gain more power or territory. Maybe it was a personal vendetta against the father for something he knew or was about to do. This line then becomes a declaration of the character's intent to right the wrong that has been done to their family. It's a very emotional and impactful line that makes the audience understand the character's motivation and the gravity of the situation.
