Detective Taller was sure he'd seen Noir steal Mae's brooch. The scuffle had caught his attention, but only when Mae said her brooch was gone he noticed it. Oldest trick in the book... but that imp had nerve, to pull it off under the nose of a detective.
"I'll be back in a second", he said and got up. If he got back that brooch, maybe he'd get some answers in return, even though he had a good idea of who the killer was by now.
He followed Noir quickly, then put a hand on the imp's shoulder. "Excuse me", he said, "but I think you have something you shouldn't have... you're not the type to wear a brooch, are you?"
(Worst point for this, but I'll leave in four hours or so... will be gone the entire weekend, so I'm sending my guess now. Also: since I won't be posting during those two days, just have me wander off/disappear/pass out randomly, if necessary. But don't let that imp get away!)
