Unjust Deserts (5E)

From publisher blurb: A 5th Edition Mini-Dungeon for 5-6 characters of levels 9-11 Visiting a desert-edge city, the characters hear of a dig taking place at recently revealed ruins a dozen miles away. They’ve missed most of the excitement but are asked to go and help the Wazir's daughter, a keen archaeologist, because of their superior experience. With the words, “Keep her safe,” he gives the party a hand crossbow and 3 packs of bolts. Reaching the busy site, the adventurers are sent to a smaller tomb some distance from the main discovery. The young woman was working there, with help, but hasn’t been seen for a couple of days. The characters find they have to fight their way in to find her, and then back out to safety!
