SPOILER ALERT
So great to have a new installment of the series. DCI Domenic JeJeune has been suspended for 45 days from his last case. He is prohibited from working any of the cases. He is not happy but decides to help on the suspected murder of a scientist at an Antarctic station. He froze to death, clutching the fuel line that had been cut, and his kit that would prove that he did not have an intrument that he could have used to cut it. The group was part of a study of climate change, and the temperature changes at the poles. It was funded by Julian Bellaire, a billionaire who is living near Domenic and Lindy's new home. He determines from information provided by Gayatri Monde, mother of Glover Boyd, husband of Tori, a director of the Bellaire Institute.
At the same time a friend of Domenic's has disappeared and there have been fires at a number of bird hides. His friend Arliss Dyer, blind but with extremely sharp hearing had overheard a man on a phone at one of the hides where he was sleeping. While not believed by all, he puts a line in the voicemail he leaves that he knows Domenic will understand. He can recognize the voice if he hears it again. So the person not wanting to be identified lures Arliss to a hide and provides a bottle of whiskey, before she sets the hide on fire.
Meanwhile Gaya sends texts to Domenic, and he determines that Alex Kasabian was murdered, he figures out that Gaya was the only one who could done it. She is on her way back to the Institute, on the ship, Oceanite, meaning "Storm Petrel", which takes a circuitous route so that the deteriorating plastic buoys that hold the monitoring equipment can be picked up and replaced. The Institute has been altering the temp reading. The deteriorating plastic smells just like the odor that is released when animals are consuming other animals. So the buoys attract the millions of storm petrels and when they collect at the buoys, it raises the temperatures registered on the equipment. The buoys that are being held at the Institute are going to be destroyed by Tori Boyd. They still have the original unaltered information. She had set up the hide fires to confuse the case when the hide at the Institute that holds the computers with the altered information also burned. She is going to be stopped by Lauren Salter, who is targeted by Tori, who puts Lauren on the buoys, which she intends to send a large charge to, killing Lauren.
Domenic rushes to the rescue. As DCS Colleen Shepherd tries to stop Domenic from interfering thus jeopardizing his job. He had been working legitimately on the murder in the Antarctic, as no country owns the land thus no country will intervene in the investigation. The murder will also not be prosecuted. Gaya commits suicide by letting the sea, in a severe storm, take her over the side. She had warned Domenic of her intention and guilt by referring to several lines from a poem by William Carlos Williams: "These". It is a desolate poem. She was committed to the Institute project, though she liked Alex and regretted needing to kill him.
Part of the story surrounds the relationship that has developed between Lauren and Danny Maik.
When it is clear to DCS Shepherd that it is putting them at risk, she realizes that one of them will have to transfer. Danny nearly dies when he goes after Lauren and is in the sea near when Tori sets off the electrical charge. There is, as usual, much information shared about petrels, climate change and the effect it has on the wildlife of the poles and the world. I love this series and the characters.
