Query: Hard to read

This was the first book I have ever read by Arthur Conan Doyle. I would not recomend reading the book. I found it very dry and hard to read. He uses textbook-like discription and his 1850's English language conflicts with the 2000's american language. The first 50 pages are rather boring and unimportant to the rest of the story. The book only starts to get some what interesting after that. There wasn't much of a twist in the ending beyond telling you who was responible for the crime. Overall the book is not worth your time.
