Query: One of the best Nancy Drew books I have read!!!

I loved this book. In my opinion this is one of the best Nancy Drew books written. I always enjoyed all of the suspence. I never knew which characters to trust in this book. This book is basically about a mysterious ghoust and a mournful tolling bell in a dark cave. Every time the ghost appears and the bell sounds water will rush through the cave and almost drown anyone around the cave. When the book begins 5 people had already been nearly drowned and 1 person had already lost their life. Nancy and George are almost drowned by the rushing water!I won't tell you anything else because it will ruin the book. I would definalty recommend this book to anyone who loves Nancy Drew books. This is one great book! Really!!!
