It wasn't until they rolled the body over that they saw it. Painted in the confines of the chalk-line, a gentle pastoral scene. Rolling green fields, dark purple trees, a small barn in the foreground. There's some cows, said someone, and yes, there they were, little brown dots grazing near the horizon. The coroners slipped the body away, and the forensic team were left there, staying for nearly an hour, debating artistic composition.
