Lord Edward's Mysterious Treasure

Lord Edward Tremaine comes to the fog-shrouded Chateau Morvan on the coast of Brittany. In this ancient building, all the inhabitants have secrets. The old vicomte demands that his descendents find a lost treasure, but he offers only hints to help the three cousins in their search. The beautiful and charming Delphine seems to be a creature of gaity and sunshine, but every now and then glimpses of something darker appear. Marguerite, the beautiful and brilliant pianist, is obviously afraid. What is it that threatens her? Antoine, who considers himself a modern man, ignores the swirling emotions, concentrating only on the money needed for him to build a steel factory.
Lord Edward wants to help his friend Antoine—and more and more he wants to help Marguerite and protect her—but can he do so before tragedy strikes?
