"The Mysterious Three" by William Le Queux is a thrilling mystery full of murder and mayhem. A classic tale of finding a killer on the run, this book takes the gentleman's code of honor and turns it upside down. After all, what is one to do when a crime has been committed, but one is bound by ethics not to reveal the identity of the perpetrator? Especially when it seems as though, without intervention, the spree has only just begun.
