The great Spatini needs his stolen medallion back for his mind-reading act at the Fulton Opera House.
What secret does the mystic medallion hold? is it responsible for Spatini's ability to read minds, make spoons bend, and make solid objects to disappear? Can it conjure up ghosts that frequent the Fulton Opera House? or does the round gold medal possess another secret?
After the medallion disappears from the Great Spatini's dressing room, Sammy and Brian are on the case. Bird-in-Hand's fifteen-year-old super sleuths collect plenty of facts but no clues. The boys meet dead ends as they tangle with adults and ghosts in a case that seems unsolvable.
