Description:

Nick and Katie are thrilled to be spending their summer at Holiday House, run by its kindly owner Mrs Holly and bustling with memorable characters — chattering Clare and the famously gloomy Gareth. With the beach and clifftops to explore, there's no shortage of adventure, but the children soon realise the place holds far more than meets the eye. A ruined old house nearby glows with a mysterious light at night, and a hidden underground tunnel leads straight to it. As Nick and Katie poke into a secret network of caves and the abandoned house, they begin to wonder who might be lurking there — and what they could be hiding from. Part of Blyton's classic Riddle (Young Adventurers) series, this is a brisk, cosy mystery full of clues, secrets, and good old-fashioned holiday sleuthing.
