One book I read over the summer is "All the Wrong Questions" by Lemony Snicket. In the beginning of the book, Lemony Snicket receives a note from 's', telling him to meet him/her in the alley, right outside the bathroom window.  Lemony Snicket finds a woman named S. Theodora Markson, who drives him to this house, where a woman tells them to steal a statue from a house close by. They end up getting caught by the local police, but manage to escape safely. 

This book is connected to "the Adventures of Sherlock Holmes" by Sir Arthur Conan Doyle because they are both confusing. In "All the Wrong Questions", the woman who tells them to steal and return a statue, that was never hers, but you do not know that right away. In "the Adventures of Sherlock Holmes", Holmes uses the power of observation and inference to figure out what people's jobs are and a lot of other things. Both of these books are very confusing. Any person who likes good and confusing mysteries will like this book.
