Another Romney Marsh story, and the most exciting one that Monica Edwards has ever told. When the fishermen of Westling are in despair because their fishing grounds are being poached by French boats, Tamzin, Rissa, Meryon and Roger—those four friends who live on the marshes and ride ponies and bathe and bicycle and have never a dull moment in their full lives—think out a wonderful plan. Why not sail a mystery ship, showing queer coloured lights and making eerie noises, out at night to haunt the French and perhaps scare them away? Will they be allowed to do it? Whose boat can they turn into a ghost? Will the plan succeed? Is haunting at sea too dangerous? Who will help? All these questions have to be answered. As well as problems, however, there are also triumphs and calamities, fights and rescues, riding and sailing, and much else besides before the end of this splendid, ghostly adventure.
