Computational demonologist Bob Howard is taking a much-needed break from
the field to catch up on his filing in the Laundry archives when a top
secret dossier known as the Fuller Memorandum vanishes--along with his
boss, who the agency's executives believe stole the file.
Determined to discover exactly what the memorandum contained (and
perhaps clear his boss), Bob runs afoul of Russian agents, ancient
demons, and the apostles if a hideous faith who have plans to raise a
very unpleasant undead entity known as the Eater of Souls.
Now Bob must use all of his skills to learn the secret of the Fuller
Memorandum in order to save the world--and avoid becoming an item on the
Eater of Souls's dinner menu...
