The carriage now made a left turn onto a gravel track that bordered an especially broad open park, called the Malieveld, where those who could afford it went riding when the weather was pleasant. No one was there today. At its eastern end the Malieveld gave way to the Haagse Bos, a carefully managed forest laced through with riding-paths. The carriage followed one of these through the woods for a mile, until it seemed that they had gone far out into the wild. But then suddenly cobblestones, instead of gravel, were beneath the wheel-rims, and they were passing through guarded gates and across counterweighted canal-bridges. The formal gardens of a small estate spread around them. They rolled to a stop before a gate-house. Daniel glimpsed a hedge and the corner of a fine house before his view out the carriage-window was blocked by the head, and more so by the hat, of a captain of the Blue Guards. 'William Penn,' said William Penn. Then, reluctantly, he added: 'And Dr. Daniel Waterhouse.'
