The Mortal Word

In 1890s Paris, a librarian and a detective must track down a killer - before the city goes up in flames. The Mortal Word is the enthralling fifth instalment in the Invisible Library series from Genevieve Cogman.
A corrupt countess. A spy in danger. And an assassin.
Peace talks are always tricky - especially when a key diplomat gets stabbed. This murder rudely interrupts a top-secret summit between the warring dragons and Fae, so Librarian-spy Irene is summoned to investigate. With her detective friend Vale, she must track down the killer - as peace hangs by a thread.
Accusations fly thick and fast. Irene soon finds herself in the seedy depths of the Parisian underworld on the trail of a notoriously warlike Fae, the Blood Countess. However, the evidence against the Countess is only circumstantial. Could the assassin - or assassins - be closer than anyone suspects?
