We were all at the party. Which of us wanted her dead?

As the smoke from the bonfire spirals into the night sky and the cool drinks slip down our throats, none of us can take our eyes off Lacey. She dances in the dunes, her long golden hair damp from her late-night swim, her smile dazzling, her blue eyes closed.

Everyone who is close to Lacey sits by the smoky fire. Her adoring boyfriend, who holds onto her, perhaps a little too tightly. Her little sister, always in Lacey’s shadow, sifting fine soft sand through her fingers, never taking her eyes off Lacey. And me. Sad and full of rage, after an argument forced the man I love to leave the party early.

When the fire burns out, we stumble away from the beach, along the cliff path – faces burned by the wind, hearts full of secrets. But Lacey never makes it home. The next morning, her body is found in the sand dunes, a heart-shaped locket missing from around her neck.

Who would have thought our beach party could end the way it did? Close friends gathered on the last night of a long hot summer – which one of us could have killed the girl everybody loved?
