Jack had developed a suspicion that he was being tailed by an agent of King Looie's Lieutenant of Police, who had unfortunately caught his eye for a moment as he'd gone through the gate. Jack knew not to turn around and look. But by watching the faces of oncoming pedestrians – particularly, scum – he could see that they were surprised by, and then scared of, someone. Jack could hardly slip off into the crowd when he was leading a great big horse, but he could try to make himself not worth following. Les Halles would be a good place for that, so he followed the crowd to the right. The dramatickal option – mounting Turk, producing a weapon – would lead to the galleys. In fact, there were very few roads out of Paris that would not end with Jack chained to an oar in Marseille.
