Recovering addict Tommy Jarret has rented a chalet to check out reports of a sea monster near the village of Drim. Then he turns up dead, apparently from a drug overdose, and constable Hamish Macbeth finds the lad's demise particularly fishy. Deciding to go undercover, Hamish infiltrates the local drug dealing trade. But his plans looks doomed when he's teamed up with a tough Glaswegian detective inspector named Olivia Chater, aka Concrete Knickers. For the Lochdubh lawman it would be equally dangerous to flounder ...or fall in love. Praise for the "Hamish Macbeth" series, include: 'An enchanting series ...M C Beaton has a foolproof plot for the village mystery' - "New York Times Book Review". 'Readers will enjoy the quirks and unique qualities of the cast ...Beaton catches the beauty of the area's natural geography and succinctly describes its distinct flavour' - "Library Journal".
