Coming Soon

First he watches. Then he strikes.
IS THE TOWPATH PROWLER BACK?
Along the Leeds & Liverpool Canal near Skipton, where peaceful narrowboats drift through idyllic Yorkshire countryside, it’s happening again.

Women report being watched. Lone joggers feel eyes following them along the towpath. Cyclists hear footsteps in the dusk.

Every woman knows that fear.

DCI Finnegan remembers 1995. He was a young officer when the Towpath Prowler terrorized this same lonely stretch of canal. Five brutal attacks. One woman who vanished without a trace. Then the predator disappeared, leaving the case unsolved.

Now DI Prisha Kumar pulls the dusty file from the cold case archive. The pattern is unmistakable: voyeurism, escalation, violence.

But is this a copycat learning from an old case? Or has the original predator returned after thirty years?

As the attacks escalate, Finnegan knows the clock is ticking. Because the Prowler doesn’t just watch.

He takes. And he’s already chosen his next victim.

A gripping thriller from bestselling author Ely North. Perfect for fans of Peter James and Val McDermid.
