Investigate the Library

The Supreme Court Library is quiet and tastefully lit. The windows that give on the outside show only the black of night.
There is a desk with reference books open and an abandoned notepad.
Among the rows of books there is a spiral staircase that leads to the floors above.
There is no one behind the reception desk, but there are sweeties for you to sample.
