When the village police receive a cryptic anonymous note, only later do they realise that it was from a murderer giving prior warning of a bloody crime: the death of Richard Marney, who is fatally stabbed during a fox hunt. Hugh Egmont, jealous of the affection between Richard and his cousin Joan, is the obvious suspect. But Egmont has an alibi - he himself had been duped out of attending the hunt by a false message. Inspector Lyly's job is complicated further by reports of something unearthly stalking the country lanes, and a local mystery writer (and her cats) intent on meddling in the investigation....
Originally published in 1943, this is a vintage murder mystery from the golden age of crime fiction.
