Ethelred Tressider and his agent Elsie Thirkettle have been invited to lecture on a creative writing course at Fell Hall, a remote location in the heart of ragged countryside that even sheep are keen to shun. While Ethelred’s success as a writer is distinctly average, Elsie sees this as an opportunity to scout for new, hopefully more lucrative, talent. But heavy snow falls overnight, trapping those early arrivals inside, and tensions are quick to emerge between the assembled group.
When one of their number goes missing, Ethelred leads a search party and makes a gruesome discovery. With no phone signal and no hope of summoning the police, can Ethelred and Elsie identify the killer among them before one of them is next?
