Berry crept quietly through the tall grass in her grandfather's garden. Philip followed her, trying not to rustle the twig in his hand. A holiday at his grandfather's house meant one thing - adventures you don't find in the city. There, between the gooseberry and raspberry bushes, hid something that no one could see but them.
