snow fell on a quiet suburb in South West England. But just after 9:00 a.m., the quiet was shattered by the sound of police sirens racing through town. The police cars came to a screeching stop on a wet street, and a veteran Detective Inspector stepped out into the cold. He walked towards a stone wall that separated the road from a tree-covered field on the other side. The Detective Inspector reached the wall, crouched down, and started digging through a pile of snow and leaves.
