The main character is a small polished anthropomorphic metal compass with a focused, curious expression, a drawn brow and a large reflective glass eye; it holds a notebook made of folded subway tickets and points a tiny needle to the floor as if marking a clue. A second character is a friendly yellow anthropomorphic umbrella with a curved wooden handle like an arm, leaning slightly toward the compass and standing just behind and left of it. A third is a pair of joyful pink mittens with bouncy little paws, placed in front of the compass and clapping. A fourth is a shy, regretful blue tape dispenser near a storage alcove with a strip of red tape trailing behind it. The scene is an indoor metro station with a wide checkerboard tiled platform, colorful posters on the wall, a shiny metal escalator rising to a glass door, a wooden notice board with visible pins, soft neon light and floor reflections. The little investigators have just found a rolled, slightly torn map on a dusty crate near the tunnel entrance; composition shows the compass unfolding the map, the umbrella leaning in to look, the mittens applauding and the tape dispenser in the background, with small details like bits of red tape, a pin and a subway ticket and warm contrasting colors.
