The Vampire Murders. Supernatural Romance

Someone is murdering fledgling vampires, the conception of which is complicated and taboo in it of itself. Such matters would be disregarded and dismissed as Vampire Business if not for the fact that the same person who is doing is is also targeting the upper society, rich elites that would not be so easily cowered by vampire nobility. It is up to Ophelia to figure out whodunnit while coming to grips with her own lineage.
She is one of the members of the Supernatural Force of investigators responsible for Supernatural Business, but is also the only one who is allowed to investigate and question those involved due to her  unique bloodline. Ophelia knows scarcely about her own background than the people who are so interested in her, but is willing to use that to her advantage. She is, apparently, of Dragon Descent. Jason Bell is a vampire who is notoriously private and dangerously powerful.
Rumor has it that he has not left his home for more than a decade. His noble and ancient lineage opens doors for the investigation and he has come forward to help with the investigation on the condition that Ophelia be the one to accompany him, though helping is not the term Ophelia would use. As the duo draws closer to the truth, they also draw closer to each other. Will she be able to resist the temptation as they solve the murder, or will Jason prove too much of a distraction? What if that is his plan all along? A distraction to prevent her from finding the murderer?
