The spring tides are the highest of the year in North Koster; the beach will be covered in particularly deep water tonight. Three men on the beach are digging a hole, covertly watched by a young boy. His intrigue turns to horror as he makes out a fourth figure – the woman for whom the hole is intended.
Buried up to her neck in the sand, the high tide is rapidly approaching. Still screaming in terror, the victim takes her last breath as water fills her nose and mouth – in her stomach, she feels her baby kick. And her waters break.
Twenty years later, a gang is beating up and killing homeless people in parks – worse still, they are filming their attacks and broadcasting them on the internet. The police have their work cut out trying to keep abreast of the crime wave.
Olivia Ronning hopes to follow in her father’s footsteps and join their ranks in the next few months after she completes her training; she has only one last hurdle to overcome over the summer break, a challenge from her professor to pick a cold case and solve it.
She chooses the beach case from North Koster. Many questions arise when she goes through the documents. She needs answers from the original investigator, Tom Stilton, but he has disappeared.
