Brought up in Ireland by his mother, Tom Chadwick returns to England when he and his sister Bea--who communicates through a monkey puppet--visit their father Keith and are told of a box that a great-aunt left them. Its contents include the photo of a distinguished-looking old gentleman in military garb: Tom's great-grandfather. Through antique dealer Mr Pfister, Tom and his best friend Pete meet genealogist Neville St Aubrey, who tells them that the man in the photo is Prince George. However he is not their relative, who was actually the man who took the picture and was an actor on the south coast of England.
