Dear Al Barqan,
This month my water bill was $71.26, but for the same month last year it was only $50.48. I was actually out of town for several weeks this time around, so there’s no way regular usage can account for the discrepancy and there are no leaks. Please help!
This is indeed an ominous mystery. I advise resorting to the enchantment known to mortals as “The Cloak of Firiel”. Once you have completed the ritual and achieved total immunity from observation, approach this den of evil they call the “Water Resources Department” and enter within. Observe the fools at their work, and listen closely to their words. Then report back to me.
