Conan Edogawa a.k.a. Jimmy Kudo is a high school detective that turns inot a 1st grader after he's forcefed a pill. Now he lives w/ a friend of his but she doesn't know he's really Jimmy and her detective dad always gets help from Jimmy but he doesn't know it. In this volume Rachel & Serena go to a special resort to make Valentine's Day chocolates but get caught in a murder case but that is just the beginning of this book. I strongly recommend this book.
