Books like The Message in the Haunted Mansion

An average ND book. Since I played the game based on this book though, I pretty much knew what was going to happen and who the culprit is, which reduced my enjoyment. However, the book has more details and characters than the game and I enjoyed that. But the plot is a bit slow at times. There were also a lot of luck and coincidences that helped Nancy solve the mystery(Like I was a bit annoyed when the girls kept accidentally discovering secret hiding places or secret rooms and people dropping clues right in Nancy's lap), which resulted in Nancy not figuring out most of the mystery on her own and having the answers come to her. Nancy also doesn't suspect the culprit at all till the end of the book, when they show plenty of signs of being guilty. Come on Nancy! Overall, this book was average, if I had to pick, I would pick the game over the book. The game is much more fun and more interesting to me. I give this book 3 stars.
