Whispers of Truth
(2026)(The fifth book in the Duncree Haven Romantic Mystery series)
A novel by Cait Byrne
Every secret surfaces in the end. And the truth beneath Duncree Haven has been waiting a very long time to come up for air.
Everyone has secrets.
Some are small. Some are the kind a family like the Sinclairs will do anything — kill anyone — to keep buried. And now, on the wild Irish coast where a journalist once came looking for a fresh start, every last one is surfacing at once.
Brenna Callahan doesn’t give her trust away cheaply. Years of hurt taught her that. But Duncree Haven was supposed to be different — new friends, a circle that felt, against all her expectations, safe. So why, one by one, are the people closest to her betraying her confidence? And why does every answer lead back to the same buried truth, the same bloodline, the same terrible thing the village has protected since long before she arrived?
Then there’s Cormac O’Rourke — the one person she’d come to trust above all others. Until a secret of his lands like a dropped match in a dry summer, and Brenna has to decide whether the man she’s fallen for is her partner in this or its final betrayal.
She’ll have to set her heart aside long enough to find out. Because the clock is running down — on Duncree Haven, on the Sinclairs, and on every last thread that’s been pulling tight since the day a body first surfaced in the harbour mist. It all ends here. Every secret. Every lie. Every whispered thing the standing stones have kept.
The only question left is who’s still standing when the truth comes out.
Perfect for fans of
Kate Morton, Kate Mosse, Susanna Kearsley, Frances Evesham, and readers who want a finale that earns every page of the slow burn that built it.
