At a Glance

Best for
Readers who enjoy British coastal and village mysteries, amateur sleuths, old records, local folklore, family secrets, humane stakes, and quiet queer continuity.
Tone
Atmospheric, evidence-led, and humane, with a light uncanny edge but no mermaid-fantasy or horror promise.
Reading order
Book 4 of the Treggan Bay Mysteries. The old-case mystery is self-contained, but Noah and Leo’s story is best read after Books 1–3.
Heat / intensity
Low heat and closed door. The relationship is established, but the book remains mystery-first.
Content note
Historical fire deaths, family concealment, isolation and confinement, care and institutional history, trauma and mental-health themes, break-in and trespass, a ghostly or uncanny element, and mild to moderate language. The old-case material has low graphic detail.

The old fire was blamed on a mermaid. Noah Yalland knows better than to trust a tidy story.

A quiet walk in the Whealings turns unsettling when Noah and Leo Petit find shell offerings among the stones and hear a scream rising from the ground below.

A dead file at the Kingsbridge Gazette pulls them towards Coplestone Cross: a fading village, a ruined house, a stopped clock, and a 1961 barn fire once explained away as the mermaid’s fury.

The story should be safely buried. Instead, every record makes it stranger. Wells carry sound where they should not. Parish pages have been damaged. School registers leave gaps. Photographs, letters, and village memory all point towards a truth someone worked very hard to erase.

With Leo beside him, Noah follows the trail through folklore and evidence, knowing that some secrets are not only about the dead.

Mermaid’s Fury is the fourth Treggan Bay mystery: a coastal, clue-led old-case puzzle with a quietly queer heart.

Why you’ll love it: South Devon atmosphere, clue-led old-case mystery, village folklore, pre-digital records, hidden family history, and Noah and Leo’s established low-heat relationship.
