A scorching heatwave marks the start of the summer in Devon. Detective Matthew Venn is called in to investigate a puzzling death, when the body of a young woman, Lottie, is found in the swimming pool of a luxurious holiday home. The girl’s best friend, Hannah, whose family owns the house, is missing. The girls had arrived a few days earlier to celebrate the end of their school exams, quickly stirring unrest in the small community with incendiary social media videos mocking the place as parochial. The fact that Hannah’s father, Paul Armstrong, is a rising political star with powerful enemies draws intense media scrutiny to the case. With the summer heat come holidaymakers, and it emerges that some of them may have stronger connections with the Armstrong family than first thought. Venn knows all too well that the real answers lie not in what people say, but in the silences that they keep.

When Jem Rosco --- sailor, adventurer and legend --- blows into town in the middle of an autumn gale, the residents of Greystone, Devon, are delighted to have a celebrity in their midst. But just as abruptly as he arrived, Rosco disappears again, and soon his lifeless body is discovered in a dinghy, anchored-off Scully Cove, a place with legends of its own. This is an uncomfortable case for Detective Inspector Matthew Venn. Greystone is a place he visited as a child, a community he parted ways with. Superstition and rumor mix with fact as another body is found, and Venn finds his judgment clouded. As the winds howl, and Venn and his team investigate, he realizes that no one --- including himself --- is safe from Scully Cove’s storm of dark secrets.

North Devon is enjoying a rare hot summer with tourists flocking to its coastline. Detective Matthew Venn is called out to a rural crime scene at the home of a group of artists. What he finds is an elaborately staged murder --- Dr. Nigel Yeo has been fatally stabbed with a shard of one of his glassblower daughter's broken vases. Dr. Yeo seems an unlikely murder victim. He's a good man, a public servant, beloved by his daughter. Matthew is unnerved, though, to find that she is a close friend of Jonathan, his husband. Then another body is found --- killed in a similar way. Matthew soon finds himself treading carefully through the lies that fester at the heart of his community and a case that is dangerously close to home.

In North Devon, where two rivers converge and run into the sea, Detective Matthew Venn stands outside the church as his estranged father’s funeral takes place. On the day Matthew left the strict evangelical community he grew up in, he lost his family too. Now, as he turns and walks away again, he receives a call from one of his team. A body has been found on the beach nearby: a man with a tattoo of an albatross on his neck, stabbed to death. The case calls Matthew back to the people and places of his past, as deadly secrets hidden at their hearts are revealed, and his new life is forced into a collision course with the world he thought he’d left behind.
