It's Autumn half-term and Louise Elliott, still only 12, has run away to her parents' holiday cottage at the Welsh seaside resort of Abersoch. That's great news for her friends Jack, David and Emily, who have also returned for a week's break with their parents and are delighted to see her again. The children set off for a walk across moorland above the neighbouring village of Mynytho. They come across a ramshackle farmhouse owned by a worried, elderly lady who is convinced it's haunted. But is it, or is her imagination getting the better of her? Lou is determined to find out. This is book three in the Lou Elliott mystery adventure series.
