The Jennifer Morgue is the second collection of Laundry stories by British author Charles Stross, published in 2006. It contains the title novel "The Jennifer Morgue", the short story "Pimpf", and an essay titled "The Golden Age of Spying". The collection is a sequel to the stories published in "The Atrocity Archives". Billington, the billionaire antagonist of the book, intends to repeat a 1975 CIA attempt to raise a sunken Soviet submarine in order to access the Jennifer Morgue, an occult device that allows communication with the dead, in spite of the hazard of awakening the Great Old Ones. Bob Howard thwarts this attempt with the added help of "Mo" O'Brien, now his wife. She plays a violin able to kill demons and undo bindings.
