Jashara and James have returned to the Palace after doing everything I can find to do in Chapter 0 (including the Whisperer and Yusuf quests). The guard comments that he sees I've found my quarry, but when I try to click on the palace gates, he keeps saying that they're closed for the night and I'll need a writ from the jprince. Of course time doesn't advance at this point in the game and I can't find anything about how to get a writ. Everything seems to imply that clicking on the gates should cause the chapter to end.

Working now!
