The Bookshop Detectives Murder Mojitos by Gareth Ward and Louise Ward

Art Deco glamour, a Cuban crime queen and a grammar-obsessed killer collide in the #1 best-selling Bookshop Detectives' high-stakes final instalment. The Bookshop Detectives are on the case! Booksellers Garth and Eloise Sherlock (and their cowardly dog, Stevie) have been roped into hosting Murder and Mojitos, a glamorous Art Deco festival event starring Cuba's queen of crime fiction. Between flapper frocks, rooftop hijinks and competitive cocktail shaking, it should be the bookshop's biggest break yet. But when mysterious parcels arrive at the shop and a body turns up on a quiet local beach, every clue points back to Arthur Pinter - the literary-obsessed serial killer from the Sherlocks' past. With the mojitos flowing and half of the town in costume, Garth and Eloise must untangle a web of old betrayals, new alliances and international intrigue before the festival's finale turns into a bloodbath. Can they protect their staff, their small town and their beloved bookshop - or will this be their final chapter?
