Somewhere, in a suitable desert in your campaign world, there's an oasis that isn't actually quite as welcoming that it seems. The Player Information on the back cover talks about the odd missing item, mysterious tracks in the sand, and strange noises, ending with a missing child whose parents are wealthy enough to finance a search mission...
Then the DM's Background lifts the lid on what is going on, and believe me, there's quite a lot going on in that desert inn beside the oasis! Malloc, the owner of The Desert Beetle, provides a good service provide you have plenty of gold but there's a whole lot more going on, most of it quite unpleasant (and not all Malloc's doing either although he does his best to get involved, and get a cut of the profits!).
There's an evocative description of the oasis and plenty of detail about The Desert Beetle itself including notes on the inhabitants and room descriptions. There's a small map of the building - a fairly typical caravanserai - and what lies underneath; but this is not player-friendly, you will need to prepare something if your players like to be shown plans of where their characters are. We also get to meet a new lifeform, the desert goblin. Bit like a Jawa from Star Wars, to be honest: I can see plenty of potential in them.
You will have to get the party there on your own, there are no suggestions for why they might be wandering around a desert. Even if you go with the concept of a doting daddy looking for a missing daughter, you will need to provide details for yourself.
However, it's a neat little adventure even if you will have to do some preparatory work (some other patrons for the inn might come in useful too). Oh, and Malloc's lash? That's the new magic item and, no, it's not a whip!
