The Ledger Beneath Lock Seven

Blue gasket grease on the glass, a maintenance hatch beneath the lock, and two donation receipts carrying the same number lead the students from the museum's cable conduit to the rowing shed. Their evidence points toward restoration accountant Gareth Pindle, the one person able to make a perfect seal look untouched.

The Ledger Beneath Lock Seven is Book One in The Greybridge Evidence Club, a realistic young adult mystery about financial deception, institutional loyalty, and restoring every name before an innocent student loses her future.
