"What did you have in mind?"

"Something to let us see the past." 

"Divination and clairvoyance are not usually things magic can do, and there aren't many safe or sane ways to do it." 

"What makes you think I care about safe or sane? I need to know for sure." 

He looks to the kobold. 

"Do you understand? What do you think? What say you?" 

"Understand some. Not want murderer do murder, not want kill person not murderer. Want safe. Say more, magic not safe?"

"Magic to learn is not safe. Need give energy-eating food and sleeping give you energy, magic to learn takes energy, takes life, takes future." 

"Future is later, past is before." 

"Okay. If murderer and not kobold, you do what?"

"Capture murderer, talk to murderer, learn what murderer wants."

She leans gently on Derek and looks up at him. "If we do that, you okay?"

"If she no say lies, then is good." 

"The easiest kind of trap will be one that could capture anyone, regardless of who or what they are. I can set one up by tonight. I just don't have a way to get her to walk straight into it." 

"Kobold see how to make murderer come?"

Headshake. "If Derek know where person, I can move person? Need go there."

"I think it's unlikely we can find the murderer with our magic. We'll need bait." 

"I have something that could work. Where do you need him?" 

"Derek..."

"I can set the trap based on where the bait is. Should simplify matters. Is there anything else?" 

He shakes his head. 

"Alright."

He glances at the kobold. 

"If you're sure. It was nice seeing you again." 

She nods. "Thanks."

Derek heads to his car.

He rests his head on the door, closing his eyes. He's mumbling under his breath. Some kind of calming mantra. 

She looks around - it's not too crowded - and teleports up to the roof of the car, where she sits and starts petting his hair.
