Serving out a suspension, DCI Domenic Jejeune is occupying himself by looking into a strange death at an Antarctic research base, which appears to have been predicted by the victim in a blog entry. Meanwhile, a quiet period has left DS Danny Maik with only a string of arson attacks to investigate, including one at a local climate monitoring facility. A body found in a bird hide might connect the two lines of enquiry, but Jejeune’s suspension means the men cannot share information. Meanwhile, Danny’s personal relationship with DS Salter necessitates a new posting for one of them. DCS Shepherd is undecided who to transfer, but dangerous developments may make the decision for her. Ensnared in a web of shared leads involving secretive Antarctic researchers, uncompromising climate scientists and billionaire philanthropists, Jejeune and Maik discover that, when the heart is involved, some crimes are beyond the reach of the law.
