Mollie Salisbury, the garden designer who helped Prince Charles transform Highgrove, is looking for a tenant for a cottage at her stately Jacobean pile, Hatfield House, near St Albans. The refurbished fourbedroom property, for rent at £500 a week, includes its own walled "secret garden". "It's extremely rare for a cottage here to become vacant," explains the estate office. Only discreet tenants need apply: the Georgian cottage not only adjoins Hatfield itself, occupied by Mollie and her husband the Marquess of Salisbury, but the Tudor palace where Elizabeth I lived as a child.
