Detective Miles Jensen is called to the lawless town of Santa Mondega to investigate a spate of murders. This would all be quite ordinary in those rough streets, except that Jensen is the Chief Detective of Supernatural Investigations. The breakneck plot centers around a mysterious blue stone—The Eye of the Moon—and the men and women who all want to get their hands on it: a mass murderer with a drinking problem, a hit man who thinks he's Elvis, and a pair of monks among them. Add in the local crime baron, an amnesiac woman who's just emerged from a five-year coma, a gypsy fortune teller, and a hapless hotel porter, and the plot thickens fast. Most importantly, how do all these people come to be linked to the strange book with no name? This is the anonymous, ancient book that no one seems to have survived reading. Everyone who has ever read it has been murdered. What can this mean?
