Murder leaps off the page when crime novelists begin to turn up dead in this intricate new novel by internationally best-selling author Elly Griffiths, a literary mystery perfect for fans of Anthony Horowitz and Agatha Christie.

Detective Sergeant Harbinder Kaur certainly sees nothing out of the ordinary when Peggy's caretaker, Natalka, begins to recount Peggy Smith's passing. But Natalka had a reason to be at the police station: while clearing out Peggy's flat, she noticed an unusual number of crime novels, all dedicated to Peggy.

When a gunman breaks into the flat to steal a book and its author is found dead shortly thereafter-Detective Kaur begins to think that perhaps there is no such thing as an unsuspicious death after all. And then things escalate: from an Aberdeen literary festival to the streets of Edinburgh, writers are being targeted. DS Kaur embarks on a road trip across Europe and reckons with how exactly authors can think up such realistic crimes...
