He’d tell Simon stories of the great merchant heroes of the city, like Étienne Marcel, who’d built the city fortifications; he’d talk about the adventurers sailing to the New World; he’d tell the boy about how this small merchant or that had made his fortune through hard work or ingenuity. So far, he had no idea whether he was succeeding or not, but he wasn’t going to stop trying. He was a Renard, after all.

It wasn’t surprising, then, that each time he saw his cousin’s house, he secretly cursed Pierre for putting him to all this trouble.

The second reason he’d cursed, however, belonged to the day. In fact, he wasn’t sure they should be taking little Simon out into the streets at all. Because Guy Renard trusted his instincts—and he scented danger.

There was something very suspicious about this royal wedding.

Guy was watchful as they came down past the Convent of the Celestines to the riverside. A defensive wall ran along the bank of the Seine for a little way. After that, they could look across the water to the Île Saint-Louis, the small, bare island covered with woods and rough grazing that lay just upstream from the Île de la Cité, where the gray mass of Notre Dame loomed ahead. They passed the old Grève embankment, where a couple of watermills on a quay jutted out into the water. The roadway was full of brightly dressed people, moving in the same direction. Along the waterside, the tall, steep-gabled wooden houses with their open galleries and balconies hung with festive garlands and ribbons stared over the river, which was full of boats and barges.

Young Simon was walking happily beside him, his father on the other side. So far, no sign of danger.

The ceremony was being held under a magnificent awning on the parvis of Notre Dame, just in front of the cathedral’s great west doors. There the king’s little sister was going to marry her kinsman, Henry of Bourbon, King of Navarre.

In a way, it was a dynastic marriage—perhaps a necessary one—for her family and for France. For although her two brothers were living, they had no male children as yet. In another generation, the Valois line of the ancient Capet royal family would die out. And who was next in line? Quite a distant cousin, as it happened. The Bourbon line descended directly from a younger son of that saintly King Louis who’d built the Sainte-Chapelle two centuries ago. The bridegroom’s father had married the queen of the little mountain kingdom of Navarre that lay between France and Spain in the Pyrenees, of which his son Henry was now king. So if Henry of Navarre did inherit the throne of France, the Bourbon and Valois lines would be conveniently joined again.

But despite the dynastic convenience, this marriage provoked one, very big question.
