It's famous Lady Lydia's wedding day! But her groom is rather suspicious, he is in fact a diamond robber!!! He is doing everything possible to steal Lydia's diamonds. He doesn't succeed but about 9 people die!!
I think this book is about 9.5 out of 10 because it's exciting but violent. I was naughty and stayed up late reading it, don't do that though!!! I'd say its for 7,8 year olds.
