Treasure at Thornhill Academy
A Gumshoe Detective Agency Mystery
New England, 1998
When a teacher is found unconscious in the archives of Thornhill Academy, the school insists it was an accident.
But a strange note, a missing inhaler, and a key that doesn’t belong to any known door tell a different story.
As a detective with the Gumshoe Detective Agency, you’ll work alongside a student informant to investigate what really happened—using a late-1990s desktop computer, a dial-up Internet connection, and your powers of deduction.
