H. P. Lovecraft, Douglas Adams, and Mickey Spillane walk into a bar in Arkham. They have a few drinks (Adams pays), then walk back out of the bar and proceed down the street to Lovecraft's steeply gabled house, where they proceed to collaborate on a novel. This is that novel. Follow our erstwhile flatfoots as they track down the minions of a particularly odious occult deity in one hilarious encounter after another. From their offices in a white-collar, high-rise office building in Houston, to a Waffle House in Wooster, Ohio, to a dungeon in rural Kentucky, to the Rock and Roll Hall of Fame and Museum in Cleveland, our heroes save the world on $200 a day, plus expenses.
