The Lady Grace Mysteries: Gold

Preparations for the wedding of one of Lady Grace's fellow Maids of Honour are interrupted when a shipment of gold, on its way to the Queen, is stolen! The culprit is a single masked horseman, all in black - or is it a gang of ruffians from the forest? The clues seem to point in several different directions and Grace, as Queen Elizabeth's trusty secret Lady Pursuivant, can't make head or tail of them.
Could one of the newcomers to court be involved? And will Grace be able to help recover the fortune?
