In a higgledy-piggledy house with turrets and tunnels towering over the sleepy Welsh village of Druith, two girls play hide-and-seek. They don't see the house's grandeur - the marmite-brown furniture no-one may sit on, or the secrets locked behind doors they cannot open: they just see lots of brilliant places to hide. Squeezed under her mother's bed, pulse racing with the thrill of a new hiding place, Dot sees something else: a long-forgotten photograph of a man, his hair blowing in the breeze. Dot stares so long at the image that it begins to disintegrate before her eyes, leaving her with just one thought: 'I think it's definitely him' ... DOT is the story of one little girl and how her one small action changes the lives of those around her for ever.
