Fleeing the Scene is an achievement that requires the player to use the Sinclair Mansion to Fremennik Province agility shortcut.
Head north just outside the fence of the mansion, at the agility shortcut log and walk past the river. Skill boosts such as summer pies will work. The shortcut is behind the mansion, do not enter the mansion grounds and players must cross this log back and forth between the mansion and the Fremennik province.
