Carter's Curious Collection

The stranger doesn't have a permanent abode, so really they're after small things they can carry around as they move from place to place. The painting... Her eyes can't tear themselves away, but she can't take it with her. She has nowhere to put it. The key is interesting, but it doesn't have a lock so it's probably decorative. The horn is really interesting; bonework is always fascinating, it's just a pity it's so dirty. The stranger would not like to use it without a good clean first. The nail... Appears to be just a nail, so why's it here? That's very curious. And chanting... That's always bad news. Always. Even in antique shops. Perhaps especially in antique shops.

They pick up the key. The nail is tempting, but where they stay there's lots of nails. When they moved, it could just be left behind and that's just not good enough.
