City of the Dead (2017)

From the introduction:

A 4th Level adventure for 4-6 players

A strange thief wandered into Waterdeep and stole from the wrong person. Now, he has died of “natural causes” on his visit to the City of Splendors. Having no known friends or relatives, he was hastily buried, along with his possessions, at Waterdeep’s Cemetery (The City of the Dead) in The Road’s End Tomb.

While the PCs are dining in the taproom at The Dripping Dagger Inn, they are approached by a stranger who claims that the unknown man had stolen a necklace from his employer, and he needs the adventures to reclaim it.

Unfortunately, the thief’s fresh corpse has been pilfered by a dire evil with unknown motives.
