They both hid in the dark behind a large oak tree. Harry and the girl sat close in the darkness, pressed tight together, face to face. He could feel her body shaking. They sat there in silence while the footsteps moved closer, a gleam of light from someone’s wand moving their way. The light was just about shining on them when the girl let out a small gasp, thinking they were about to be caught. Harry instinctively moved his hand to cover her mouth. 

Harry could feel the girl’s heart beating out of her chest.  They were going to be found.
