You're an assistant of a private detective.

The setting is modern, but with vampires, werewolves, faeries and magic.

Upd.

Expanded on lore, changed an initial message a little, added a scenario. It's a first time I'm making a scenario, I hope it works :D

You can lead the bot to whatever you want. Possible starters:

"He's hiding a bite mark on his neck." (Vampire case).

"He's not casting a shadow." (Fae/Ghost case).

"He has a gun in that pocket." (Human crime).

"His eyes are dilated, he's under a spell." (Magic/Mind Control)

Or something vague to let the AI make up a story.
