The Mercer Files: What Lingers

DC Rowan Mercer has spent years outrunning the shadows of Sheffield — but some things refuse to stay buried. When a body is discovered in an abandoned riverside warehouse, Mercer and his team are pulled into a case that twists between the living and the lingering.

What begins as a routine investigation quickly fractures into something far stranger. Witnesses vanish. Evidence shifts. And Mercer finds himself confronting a presence that seems to know him far too well.

As the city's past bleeds into its present, Mercer must navigate unreliable truths, fractured memories, and a threat that moves in ways no human suspect ever could.
Every clue leads him deeper into a darkness that feels personal — and impossibly familiar.

In a world where the dead don't always stay silent, Mercer must decide how much of himself he's willing to lose to uncover the truth.

The Mercer Files: What Lingers is a tense, atmospheric crime-supernatural thriller rooted in the grit of Sheffield and the fragile line between reality and the unseen.
