When disillusioned detective Nia Tremeyrick stumbles upon a

30-year-old cold case in her Pembrokeshire seaside town, she

relishes the chance to prove herself to her arrogant male colleagues.
But with the identity of the victim remaining a mystery, and her own family drama dragging her down, she is struggling to piece together the truth.
Meanwhile, back in 1984, bookish teenager Cerys Pritchard is expecting an uneventful summer, until she is persuaded to attend an illicit party in an abandoned hotel by her rebellious new friend
Kay Abbot.
By the end of summer, one of them will be dead. As Nia digs deeper, she fears the case that was supposed to make her career will turn out to be her worst nightmare.
But who was killed that deadly summer? And why?

Claire Back was born and raised in Pembrokeshire, and has always felt a deep connection to this part of the Welsh coastline. After a successful career in finance, she retrained to work in Early Years education. She is currently writing her second novel - another mystery set in wartime Wales. A keen walker and gardener, she lives with her husband and two spaniels in Wrexham. Her debut novel, A Deadly Summer (2026) is described as a cross between ITV’s Broadchurch and Unforgotten. The story is an atmospheric dual-timeline mystery set on the rugged Pembrokeshire coast between 1984 and 2015. It follows Detective Nia Tremeyrick as she investigates a 30-year-old cold case that unearths buried trauma and lifelong secrets within a small seaside community.
