A GIRL sits crouched over her knees on a stile close to a river. A MAN with a silver badge stands beside her, clutching the worn top plank. THE GIRL'S level brows are drawn together; her eyes see her memories. THE MAN'S eyes see THE GIRL; he has a dark, twisted face. The bright sun shines; the quiet river flows, the cuckoo is calling; the mayflower is in bloom along the hedge that ends in the stile on the towing-path.
