Book 4: The Dunes

A body buried in the sand.

A pattern no one wants to see.

A killer who isn't finished yet.

When a young woman's body is discovered in the dunes of Lytham St Annes, Walker is handed a case already under intense scrutiny. But when more victims are uncovered, it becomes clear the past isn't buried — and neither is the truth. With pressure mounting, Walker takes a dangerous gamble that risks everything.

"Well-paced, imaginative, and utterly disturbing." — The Book Commentary

Book 5: The Castle

A body staged for all to see.

A message no one can ignore.

A mystery that refuses to stay solved.

When disturbing clues emerge from Lancaster's oldest institutions, Walker is drawn into a case steeped in history, secrecy, and public outrage. Every lead raises more questions. Every answer tightens the noose.

"A timely and intense detective thriller." — SPR Editorial Review

Book 6: The Wetlands

A body claimed by the landscape.

A place where nothing stays still.

A truth that refuses to stay hidden.

When a man is found dead in the wetlands of rural Lancashire, Walker enters a case where the terrain itself becomes part of the investigation. What begins as routine soon fractures — revealing a disturbing reality shaped by control, obsession, and isolation. In the wetlands, nothing stays hidden forever.

"Viscerally gripping and methodically plotted." — SPR Editorial Review
