Sycamore Gap

The explosive second book in internationally bestselling author LJ Ross's DCI Ryan Mystery series, a moody, chilling mystery full of obsession, betrayal, and a history that won't stop repeating...

The past never stays buried for long...

Detective Chief Inspector Ryan thought he'd left his past behind. But when the skeleton of a young woman is discovered inside an ancient Roman wall at Sycamore Gap, the case pulls him back into the darkness he's tried to forget.

The victim has been buried for a decade--and every clue Ryan uncovers only deepens the mystery. As the investigation unfolds, old secrets surface, and Ryan finds himself drawn into a deadly game of cat and mouse with a killer who always seems one step ahead.

Set against the haunting backdrop of Hadrian's Wall, Sycamore Gap delivers gripping twists, relentless tension, and a chilling reminder that the past is never truly gone.
