When a greedy ghost and a bunch of goblins get together, it's not surprising that there's soon a situation that requires a party of adventurers to deal with it. The adventure background outlines what has been going on and provides several hooks to get the party involved.
The adventure outline is simple: the party should track some rather organised (for goblins) goblin raiders back to their lair, then explore the caverns beneath to find a long-lost underground temple. These locations are mapped clearly (and quite beautifully... although all secrets are revealed, these are DM maps rather than ones you can show to your players), with plenty of detail about who and what can be found there and likely reactions to the party's arrival. In places, advancing the adventure depends on a successful skill check (generally Perception) so it's worth thinking about other ways of keeping things moving if everyone flubs their rolls. There's also a quite difficult puzzle to solve at one point.
This is a well-presented straightforward adventure with plenty of combat and underground exploration... and the treasure to be gained includes the main antagonist's diary which can be used to fill in the backstory for your players (a neat touch). A solid adventure to further a party's career.
