Double Homicide

"Two dead homicide detectives...Two bullet wounds each...In two days' time...Kevin Tallon knew them both back when he worked for the Dallas Police Department. One was his former partner and mentor. The other, an old rival - and Tallon would be at the top of the list of suspects, if he hadn't been halfway across the country at the time.Both families call him in on the case. They're definitely related, but how? If he's not careful, he might become Corpse Number three.Of course, vampires like him are damn hard to kill."
