What news did the messengers bring chauvelin chapter 27

I think it was actually a soldier that gives him the message. The soldiers tell Chauvelin that they found out Percy had talked to a Jew named Reuben about borrowing his horse and cart later that night to go down the St. Martin road. Chauvelin demands that they find Reuben, but they can't find him and instead bring a fellow old Jew who claims to be a friend of his.
