There's a new store opening in Castle Rock, and the whole town has noticed its special green awning. Questions arise as to what it will sell, and whom exactly the proprietor is, but nobody ever expected the severity in discovering such simple things. Treasures that appear otherworldly in their perfection start to become prized possessions, soon enough causing disarray in the town's day to day activity. There's something too good to be true about Needful Things.
Matt Faustus, whose very soul is connected to a high ranking fiend, finds himself neck-deep in a new case - one he accepted despite being warned about the possible ramifications. A little girl is missing, abducted by the family's house-cleaning demon, and it's his job to find her. Eager to earn that paycheck, Matt's enthusiasm soon lands him in trouble within the Hellspawn society, though that sure doesn't stop him.
