In the short story The Mystery of the Blue Jar, Heather Cottage is a cottage located near the seventh tee of the golf course at Stourton Heath. The current residents are a French professor, suffering from consumption, and his daughter. While playing on the golf course, Jack Hartington keeps hearing a woman's voice calling "Murder--Help! Murder!" coming from the direction of the cottage at about the same time every morning.
According to Dr Lavington, an acquaintance of Hartington, the cottage was first tenanted by an old gardener and his wife. After he died, a builder bought it and modernised it and then sold it to one Mr Turner who lived there for a while with his wife. Then early one morning the Turners left hurriedly. Mr Turner later write to the house agents instructing them to sell the house as quickly as possible. The house was then taken over by the French professor and his daughter. What was suggestive, according to Lavington, was that while Mr Turner had been seen since that time, nobody seems to have seen Mrs Turner.
Resolving this mystery would form the main plot of the story.
