Bob Howard's career in the Laundry, the secret British government agency dedicated to protecting the world from the supernatural, has involved brilliant hacking, ancient magic, and combat with creatures of pure evil. It has also involved a wearying amount of paperwork and office politics, and his expense reports are still a mess. Now, following the invasion of Yorkshire by the Host of Air and Darkness, the Laundry's existence has become public, and Bob is being trotted out on TV to answer pointed questions about elven asylum seekers. What neither Bob nor his managers have foreseen is that their organization has earned the attention of a horror far more terrifying than any demon: a government looking for public services to privatize. There are things in the Laundry's assets that big business would simply love to get its hands on . . . Inch by inch, Bob Howard and his managers are forced to consider the truly unthinkable: a coup against the British government itself.
