When a priceless medieval medallion vanishes from Eltham Palace, suspicion falls upon the most vulnerable suspect of all: a ten-year-old girl from a charitable industrial school.
Summoned by a desperate headmistress, Sherlock Holmes and Dr. Watson uncover evidence of a sophisticated scheme exploiting public trust, charitable sentiment, and England’s historical heritage. Moving from institutional classrooms to museum archives and midnight investigations on ancient grounds, Holmes must expose a conspiracy that threatens both a child’s future and a nation’s cultural legacy-proving once again that the smallest clue may reveal the greatest crime.
