Smashing Things

From the introduction:

Players get hired by One-Eyed Mary, owner of a local pawn shop and the head of the Black Hoods gang. Mary is angry because magister Baldwin, a local wizard, and alchemist, is way past the date he should pay his debt. And the debt is enormous. Rare magical mushrooms, fairy dust, unicorn horn, a big bag of black lotus petals, and one particularly exotic toad worth over thousand gold pieces - these are just a few things the Black Hoods provided for Baldwin. No one dares to anger Mary, but most of all, no one dares to ignore his debt to her when she says the debt is due. And the Baldwin's debt is severely overdue.
