"Think of something that could be a clue. The key is a lake, do you have a place to live by the lake?" William said to Catherine, hoping she would remember something.
Catherine tried to remember what she might have missed. She was starting to recognise that her mother had left behind several empty castles, but which court Harry had gone to, and she didn't even know.
"Is it possible Harry lives in one of Mother's empty castles? But I don't know which castle is near the lake," said Catherine.
"We should seek information from people who live in this area," said William.
The two of them ended up going around looking for information. Finally, someone said that a few kilometers from the village, a large lake with a small island in the middle. According to rumours, the island and the castle is private property, and no one can enter haphazardly there.
"It seems we have found the answer. We have to find a boat to cross the lake," said William.
