A Game of Blood — Julie Ann Dawson

A series of kidnappings leads detective Mitch Grogan to the home of the wealthy and eccentric Darius Hawthorne. What he discovers there unleashes a chain of events that not only threatens his life, but his sanity. Grogan finds himself caught up in a deadly game with a three hundred year old vampire looking for a worthy adversary. But more than boredom drives the cunning Hawthorme. His attempts to push Grogan to the breaking point are more than cruel entertainment. They serve as a test to see whether or not the mortal is ready to help him hunt an even more deadly foe.
