Description: Detective Patrick Gallagher is no stranger to Glasgow's shadowy corners, yet the fog-filled village of Lochmore presents him with an unfamiliar and eerie gloom. Daniel Mercer is meticulous. He doesn't just kill; he observes, he records, and he perfects. With a notebook full of victims and a mind built for the hunt, Mercer believes he is untouchable.
But as the hunt moves from the rugged cliffs of Scotland to the isolated coast of Ireland, the line between predator and prey begins to blur. Gallagher is closing in, but Mercer has one final move. In this high-stakes game of cat and mouse, justice isn't just found in a courtroom-it's found in the soul.
