July 2017. Sexagenarian twin sisters, Hetty and Lottie, are very enthusiastic about having their attic converted into living accommodation and anticipate much excitement during the summer months while the work is in progress, especially so when Lottie's seventeen-year-old grandson, Zac, arrives to stay with them during the school holiday. However, what they have not anticipated is the discovery of an old suitcase concealed beneath the floorboards in the attic. Its contents suggest it was packed during World War Two and this puzzles them. Why is it there? Who did it belong to? Who put it there? And why is it hidden beneath the floorboards? "We need answers!" declares Hetty. And that was just what the sisters and their friends set out to find. 'The Suitcase in the Attic' is a light-hearted story and the third in the Pentrillick Cornish Mystery series located on the south coast of West Cornwall.
