“Wait, then,” said the duke, fumbling in his pocket. “Wait,” he continued, renewing his fruitless search; “it shall not be said that such devotion to a grandson of Henry IV. went without recompense.”

“Here is what you are looking for,” he said.

The duke opened the purse and wanted to empty it into Grimaud’s hands, but Grimaud shook his head.
