Author Caleb Carr was commissioned by the estate of Sir Arthur Conan Doyle to write this new Sherlock Holmes adventure. Holmes, his brother Mycroft, and the faithful Watson join forces to solve a double murder in an Edinburgh palace that seems eerily like a murder that took place 300 years ago. Are the rumors of a ghost possibly real? Who of the Queen's supposedly loyal servants can truly be trusted? Carr writes this one in the manner of Doyle, so it's unlike his earlier historical mysteries, and an easier read, if you don't get bogged down in the archaic language.
Caleb Carr did a good job of writing in Doyle's style. I thought it was ok, the book really wasn't long enough, and to be honest the story was lacking in something. I thought Angel of Darkness, and the Alienist were better works by Carr.
Another great book by Carr.
