The first thing Brett Martin noticed was a bicycle lying abandoned on a remote mountain road in the French Alps. Nearby, a BMW sat against an embankment, its engine still running. Then a little girl staggered out of the undergrowth and collapsed in front of him. Martin, a former RAF pilot enjoying an afternoon cycle ride, believed he had stumbled upon a terrible road accident. He had no idea of the horror awaiting him.
It was September 5, 2012, and the scene was a secluded lay-by in the wooded mountains above Lake Annecy, one of France’s most picturesque holiday destinations. Within minutes, Martin would discover something far more disturbing than an accident. What had happened on that narrow stretch of road would become one of Europe’s most baffling murder mysteries, drawing investigators into a labyrinth of family secrets, international connections, suspicious coincidences and extraordinary allegations.
The investigation would stretch across several countries, uncover deeply personal disputes and bring detectives into contact with individuals whose backgrounds seemed more suited to a spy thriller than an ordinary criminal inquiry. Arrests would follow, along with forensic discoveries, startling revelations and leads that appeared to promise a breakthrough before collapsing under closer scrutiny. Even the question of who had been the intended victim would become a mystery in its own right.
Fourteen years later, the case continues to trouble investigators, with new forensic examinations, renewed inquiries and developments as recently as this year keeping the search for answers alive. Behind the sensational theories lies a devastating crime whose consequences have endured long after the headlines faded. To understand how an apparently ordinary family holiday became the centre of such an extraordinary investigation, the story begins with a British engineer, his wife and their two young daughters.
