An occult assassin, a living god and an elderly queen face off in The Regicide Report, the thrilling conclusion to Charles Stross’ Hugo Award winning Laundry Files series.

After 60-plus years in power in the U.K., Queen Elizabeth II has gathered a surplus of mana from believers spread across the British Commonwealth. That makes her a threat to the Elder God recently installed as Prime Minister—and a target to a shadowy faction within the Laundry looking to depose the Black Pharaoh.

An assassin is dispatched to take out Queen Elizabeth and neutralize the threat of the Black Pharaoh. Bob Howard and Dominique "Mo" O'Brien return for the last time, reluctantly pressed into service protecting the queen.

Plus, Mhari Murphy and her team, many of whom are now infected with vampirism, are back from their mission to Washington D.C. with mixed success.

God save the Queen—someone has to.
