A killer on the loose, and a village gripped by fear. Can the Shell House Detectives save Porthpella?

Springtime on the Cornish coast and Porthpella's artistic community are throwing open their doors, welcoming visitors to the annual Arts Trail. And this year, celebrity artist Harrison Loveday is the guest of honour.

However, the light mood soon darkens when there's a dramatic death at the opening-night party, and after threatening messages start appearing around the village, fear takes over. Before long, Porthpella is shocked by a second brutal murder, and whisperings of a 'serial killer' start to circulate.

With the press descending on the Arts Trail for all the wrong reasons, the Shell House Detectives find themselves vying with the police to hunt down the killer, fast. As the pair uncover bitter rivalries and hidden agendas, plus a growing list of suspects, the question of who has both the means and the motive makes this the most complex case Ally and Jayden have faced yet.
