Query: A cheap ploy to sell a sequel !!

I have never read an Irene Adler novel and so was intriqued by the idea of a Victorian female detective. I bought this to read on a long flight. To make this short - don't waste your money. After slogging through some of the most rambling, cumbersome prose I can imagine, waiting for all the threads to be joined, the book simply ends in mid-story! This was one of the most blatent ploys I have ever seen to get you to buy another book in this series. I found this so insulting that I would not buy another one of this authors books simply as a form of protest.
