Have You Caught Me Yet?

1927 New Orleans. A seemingly perfect time, though what you see on the cover isn't always the case. When fourteen people suddenly drop dead in one night, no wounds, no signs of foul play, they just drop like flies, local police are put on the spot. But without a lead, or anything to start with, they found themselves running in circles. Something wasn't right, however, as fourteen people don't just drop dead in one night without any reasonable explanation. So the case slowly goes cold.
Now, almost 80 years later, a young detective by the name of Harley, picks up the forgotten case, becoming obsessed with the mystery of it. After countless attempts and begging, she convinces the police to reopen the case as her first working case, but where does she start? The killer left almost no traces, the only thing left behind on the scene being a single syringe with no fingerprints.
While she picks apart her mind, she begins to feel off, like someone is teasing her. Like the killer is baiting her by dropping another fourteen the same way as before. No traces of who it could be, no wounds, no weapons, no blood. Just bodies.
Harley is frustrated, but yet, she can't stop, a voice constantly teasing her. "Find me yet?"
