Gerry Wade is famous for over-sleeping, but when a group of his fellow young guests at a country house weekend decide to play a prank on him by setting eight alarm clocks to go off in his room early one morning, they are rewarded with a nasty surprise. This time, poor Gerry is quite literally dead to the world. As the police descend upon Chimneys, the historic estate of Lord Caterham, the youthful friends—led by the bold and clever Lady Eileen “Bundle” Brent—take investigative matters into their own hands. As more victims turn up dead and clues seem to point to a wider plot, Bundle and her pals risk their lives to find the murderer before he kills again.
