>"I don't think she's been on the ship long enough to recognize the crew members' scents, wouldn't be able to detect what smells don't belong. But I'm pretty sure Chisato isn't the only crew member you have that knows this girl was on board. I think Chisato may have put her in this box, but I don't think she was the first one that found her."
>"You might find it comforting, though, that she's the only mouse on board. She said I was the first mouse she'd seen in a while."
Possible idea: Take the mouse to Murasa's cabin, and see if it recognizes any people smells there.
If nothing else, it shouldn't take more than a few posts. Assuming Murasa wants the mouse in her cabin. But given that she only got close to two crew members, if she picks up something in the cabin that we couldn't, it could just be another crewman that she hadn't met. I'm honestly not sure it's worth it.
I think we should go with Murasa to have a chat with Chisato about her new pet, because I'm quite curious what a sailor would be doing with a pet mouse. And after that, we check out the harbormasters' office to see if our theif left a clue there.
