threat, this time not supernatural but political; the Prime Minister uses the Laundry as a scapegoat and dissolves it, to be replaced with a public–private partnership. The mastermind behind this plan turns out to be an old antagonist from The Apocalypse Codex, Raymond Schiller, still trying to bring about the end of the world. The rump of the Laundry executes a coup in cooperation with the surviving cultists from The Fuller Memorandum, bringing Britain under the rule of Nyarlathotep as a lesser evil. The Delirium Brief is published by Tor. According to Stross, the book was somewhat delayed due to the Brexit referendum, as the pro-Brexit result required a large rewrite to reconcile the politics portrayed in the book with the real-world developments. The Labyrinth Index The Labyrinth Index is the ninth book in the Laundry Files series. It is set in Winter 2014/early 2015 and was released in October 2018. Mhari Murphy is the protagonist. She has been elevated to the House of Lords (taking the title "Baroness Karnstein") and serves under the new Prime Minister following the Laundry-engineered overthrow of the Government described in the previous book. The new Prime Minister Fabian Everyman (an alias of Nyarlathotep) sends Mhari to the United States on a mission to discover what has happened to the now-missing President and who is running America in his stead. There she finds that the Black Chamber has made the citizenry forget the very existence of the President and have taken over the US Government. The Black Chamber's plan, echoing the Laundry's UK plan in the previous book, is to install a Lovecraftian entity (Cthulhu in this case) as the head of the US Executive and thus survive and fight the crisis caused by CASE NIGHTMARE GREEN, which is well underway at this point. Mhari and her team try to evade the deputy director (nicknamed DeeDee) and her agents, and despite fatalities manage to free the President to broadcast a reminder of his existence to the populace. Mhari and the survivors of her team then return to the UK, leaving the President behind as he struggles, and eventually fails, to reassert his authority. But the struggle occupies US forces and so buys time for the United Kingdom, which was of course the Prime Minister's plan in the first place. Mhari keeps her job and is congratulated, and the novel ends with her contemplating her future
