Explain how Bear and Crispin enter the town of Great Wexley without being stopped by armed soldiers who guard the entry gates in Crispin: The Cross of Lead.

With a bounty on his head, Crispin cannot simply walk into Great Wexley. As Bear and Crispin approach the city, they can clearly see that the guards outside the city's gate are closely questioning the people who wish to enter. Bear correctly assumes that the guards are looking for Crispin. He hatches a deceptive plan to get past them.
Instead of trying to sneak quietly into the city, Bear decides that they should do just the opposite. He tells Crispin to take out his flute and play a diddy. Dancing joyfully along to the music, Bear attracts the crowd over to him. They start cheering and laughing along as they enjoy the impromptu show. Even the guards join in. They must assume that wanted fugitives would not be so bold as to call this much attention to themselves. Consequently, Crispin and Bear are permitted to enter the city without any further questioning.
