The Postscript Murders by Elly Griffiths
When 90-year-old Peggy Smith is found dead in her seaside apartment, it’s assumed to be from natural causes. Then her carer, Natalka, finds business cards describing the dead woman as a ‘murder consultant’. It seems that Peggy had a retirement job – helping crime writers think of gruesome ways to kill their characters. When one of Peggy’s clients is found dead, Natalka teams up with two friends to solve the case, to the irritation of DS Harbinder Kaur and the local police. The trail leads the ill-assorted quartet to a crime-writing festival in Aberdeen and another mysterious literary death.
