Midnight Private Eyes

Midnight Private Eyes is an American animated fantasy television series created by Dana Terrace for Cartoon Network. It was produced by Cartoon Network Studios and Flying Bark Productions.

Synopsis
The series follows Valerie Kipperson, a fiction-obsessed teen, settling into her new apartment after completing high school and ready for what comes next. What comes as a surprise to Val is that her new roommate is a vampire! The vampire, Cassius von Lovus-Shwarzius, is a mocking representation to his race, having replaced his taste for blood in favour of pizza of all kinds and developed a tolerance to sunlight over the centuries. Strapped on cash, Cassius reluctantly agrees to let Val turn their apartment into a detective agency for the supernatural creatures and entities seeking assistance when the sun sets.
