Medals in the attic

"Annie Dawson is enjoying rummaging through the jumble of memorabilia, old toys, and discarded furniture in the attic of Grey Gables, the stately Victorian house in Stoney Point, Maine, that she has inherited from her grandmother. But when she discovers a carved wooden case holding two World War II military medals she is dumbfounded...and troubled. Grandpa Holden's military service medals are on full display in the living room. Are these also Grandpa's? If so, why are they hidden away where no one can see them? And if not, whose are they? Why have they been kept in secret in the attic of Grey Gables all these years?"--Publisher's description.
