In the complex tapestry of Wizarding Britain, a single loose thread can unravel the most intricately woven of plans.
In October 1983, a seemingly minor discrepancy in a goblin accounting ledger is discovered in an audit, and the investigation it sparks begins to unravel the plans of some highly placed people in the Wizarding World. It changes the trajectory of everything and sets Harry Potter, Sirius Black, Narcissa Malfoy, Minerva McGonagall, Ragnok Winterkill, and Amelia Bones on new courses in their lives.
