As soon as I read the blurb of this book I knew I would love it. It was just as good as I expected. The storyline was so random but so interesting. It is slightly unrealistic as I can not imagine the queen of England ever behaving like this but it is a nice relaxing read. I am a massive fan of Agatha Christie and I could see links to her style throughout this book which I really liked. Also I loved the cover of the book, as I felt it was very eye-catching and made me want to pick up this book and read it. I have already recommended this book to many family members and friends and they are very excited to read this book too. I am looking forward to reading more books in the series and I have heard the author is going to be releasing more books soon. I would say this book is suitable for teenage children all the way up to pensioners and there is something for everyone in this book.
