The Affair of the Box (Spoilers for light fingers)

By the way, this also has spoilers for the affair of the box (I couldn’t fit that in the title).

So I just opened the box, and since I have completed all of light fingers that exists right now, I know that it was a moon-miser inside the box. Is there any point in finishing the affair of the box, or will it just tell me a bunch of stuff I already know?

The Affair of the Box is certainly worth finishing.

Not to mention the affair pays out well.
