I'm not sure specifically as I haven't read this exact novel. But generally, it might be about a situation where a villain makes a wrong move by coming to the wrong house, and perhaps there are various consequences, battles, or revelations that follow from this mistake.
The main characters would probably include the villain. He is the one who sets the story in motion by coming to the wrong place. Then there could be the people living in the house. They might be ordinary people who are suddenly thrust into a dangerous situation, or they could be some sort of protectors or even hidden heroes. Maybe there's a wise old character in the house who has some knowledge or power that can be used against the villain, or a young and brave person who decides to take on the villain directly.
Most likely it isn't. Usually, such titles are works of imagination or inspired by various elements but not based on real events. The story could have been crafted to engage and captivate the audience rather than being a true account.
It's a really heartwarming phrase. It often implies a strong bond of friendship. In many stories, it could mean that there's someone who will always be there for you, through thick and thin, just like in the 'Toy Story' franchise where Woody says this to Buzz and other friends. It's about loyalty, support, and the assurance that you're not alone.
Definitely not. 'Wrong House' is purely fictional. The story and events in it were invented by the scriptwriters to give viewers a suspenseful and engaging cinematic experience.
