The Wetlands: A Lancashire Detective Mystery

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

A body reclaimed by water

A landscape shaped by secrets

And a case that refuses to stay buried

When a man is found dead in the wetlands of rural Lancashire, DCI Jonathan Walker is called to what appears to be a tragic accident.

It isn’t.

As Walker and DC Shelly Briggs investigate a series of suspicious deaths across Martin Mere, Mere Sands Wood, and Brockholes, they begin to suspect someone is using the landscape itself — the floods, the isolation, the treacherous terrain — to conceal murder.

But the deeper they dig, the more the case turns inward. Evidence vanishes. Assumptions fracture. And the line between protection and control begins to blur. Then the investigation takes a devastating turn.

With lives at risk and the truth slipping further out of reach, Walker faces a case that will test not only his judgement — but his will to survive.

Bleaker and more intense than previous cases, this investigation strips away comfort and certainty — revealing how easily safety can disappear, and how quickly good intentions can become dangerous.

Dark, atmospheric, and psychologically charged, The Wetlands is the most demanding case of Walker’s career yet— a gripping British police procedural exploring obsession, isolation, buried trauma, and the cost of believing you know what’s best for others.

Perfect for readers who enjoy the crime fiction of Ann Cleeves, Peter James, LJ Ross, Rachel McLean and Wes Markin.

The Wetlands is the sixth book in the DCI Walker Crime Thrillers, a bestselling British detective series set across Lancashire and the North West of England. Each book can be read as a standalone case, but the full story is best enjoyed in order.
