We discuss Chapter 18 and 19 in which Dresden and Murphy enjoy the nighttime ambiance of Wal-Mart and work on gardening projects with Grum.
Dresden meets with Murphy at a local Wal-Mart and tells Murphy everything that is happening. While the two discuss the case, the lights go out and a mysterious malevolent mist enters the building.
Harry and Murphy find themselves under attack and start dividing Walmart into useful potion and spell opportunities. They run into Mr. Untouchable and things get worse.
