BEFOREA man running along a remote clifftop path on an icy-cold February morning.A woman standing on the cliff's edge.A red scarf on the ground between them. AFTERThe man is alone on the cliff - adrenaline pumping through his veins.The woman is on the beach below - dead.The red scarf is also on the beach - beautifully (and impossibly) wrapped around the woman's broken neck. WHAT HAPPENED? Two lives colliding by chance?Or a revenge decades in the making?
