"The year is rapidly drawing to an end, Hettie the tortoise is hibernating and Agnes, Charlie, Marshall, and the other elderly residents of Sunset Hall are going stir-crazy at home. They've had enough of broken heating, draughty bedrooms, and Christmas jingles on the radio. And to top it all off, another series of murders is rocking the hamlet of Duck End. It seems like every villager and his dog is trying to make up for all of the thwarted murders of the past thirty years. Most unpleasant! The residents of Sunset Hall don't want anything to do with the criminal activities. So when Edwina manages to slip onto Marshall's computer in an unobserved moment and promptly wins a stay in an exclusive coastal hotel in Cornwall, the Sunset Hall crew doesn't waste any time in deciding to join her. After all, Edwina can't be let loose unsupervised on a presumably civilized party of hotel guests. But they've barely unpacked their bags when Agnes sees something unsettling from the terrace of the hotel: two figures in hoods walk away from the hotel along the cliffs, but only one returns. Worried she's witnessed a murder, Agnes tells the others. At first nobody really believes her, after all the crew have enough to do working their way through the incredible menu, exploring the hotel's wellness-landscape, navigating old and new love affairs and adopting a boa constrictor. But when a storm causes a piece of the road to collapse into the sea and the hotel is cut off from the outside world, it becomes clear that a murderer really is on the loose-and they're trapped, just like all of the other guests!"--
