The Mouldavian Discrepancy

As the telegraph system expands across the Discworld, it occasionally runs into problems. For example, there's an accounting discrepancy showing up on the new line into Lower Mouldavia. The Grand Trunk employs people like you to fix problems like this - which may mean struggling through gods-forsaken forests in the depths of winter, climbing broken towers as the winds howl in from the Rim, fending off angry local wildlife, getting mixed up in local politics, and sometimes, even, on a bad day, accountancy.

But hopefully you won't have to go that far this time.
