Lies in the Dark — Agnes H. Hagadus

Andrea has known of vampires and demons a long time. The world of darkness has always seemed to touch her life. She is a private detective that specializes in unusual cases. But things are not what they seem. A new employee comes aboard just as a new case comes about. Alicia specializes in computers, but is that all? And Andrea has one friend. A friend with a long past, for she is centuries old. Is Gina really a good vampire? Or have lies been told? And can Andrea distinguish between those lies and the truth? For those lies in the dark may cost her everything.
