[aisle] Another Book Title Help

[Crystal Roel]

Group, I have another student stumping me with a book description and I need your help.

- 3 kids live in their grandpa’s house
- The parents of the kids are missing or dead (part of the mystery)
- There is a woman that is wanting something in the house
- The kids are going to “throw a party” and have guests come over, including this woman that wants something, so they can catch her or something like that.

Any guesses to what this book title would be?
