The House of Arden

Young Edred Arden and his sister Elfrida have inherited Arden Castle, but they will loose it forever unless they can find the long-lost treasure of the Ardens before Edred's birthday. With the aid of the Mouldiwarp of Arden -- a tempermental but magical golden-furred mole -- they travel back thorugh time to Tudor, Stuart and Napoleonic days to search for the missing treasure.
