In North Devon, where the rivers Taw and Torridge converge and run into the sea, Detective Matthew Venn stands outside the church as his father's funeral takes place. The day Matthew turned his back on the strict evangelical community in which he grew up, he lost his family too. Now he's back, not just to mourn his father at a distance, but to take charge of his first major case in the Two Rivers region; a complex place not quite as idyllic as tourists suppose.

A body has been found on the beach near to Matthew's new home: a man with the tattoo of an albatross on his neck, stabbed to death. Finding the killer is Venn’s only focus, and his team’s investigation will take him straight back into the community he left behind, and the deadly secrets that lurk there.
