4. Prince Rupert’s Birthday

Nicolas, Jonathan, Sarah and Matthew find themselves in Merry England, many years ago, and unexpectedly meet the young Prince Rupert who is the same age as Jonathan and looks exactly like him. They are so alike in fact, that Prince Rupert suggests they change places for a day, because it’s his birthday and he says he’d rather have the day off than open presents, and besides, Jonathan can keep the presents. So they change, but things are not what they seem and Jonathan is led into another harrowing adventure.
