The White Riders

In Romney Marsh near Hastings, Meryon, Roger, Rissa and Tamzin are upset to learn the marsh they love is to be turned into a holiday camp, and the Merrow family to be thrown out of the farm they have lived in for decades. When the children learn of the legendary White Riders, smugglers who once rode the marsh disguised as ghosts, this seems a perfect weapon to combat the idea of a holiday camp.
