The Case of the Scrupulous Pawnbroker (5E)

From publisher blurb: For 4 Level 3 PCs The PCs may have used the services of a local half-elven pawnbroker, Latricus. known to be stern, cold but fair in his dealings. Now they find his store open, none of his assistants present, and the door to his basement office (where serious transactions took place) invitingly ajar. Maron, a nasty sorcerer, and her thugs have recently decided to change the nature of their transgression with the pawnbroker and the PCs are just in time.
