Simon le Bon and other Duran Duran band members milled around the set, but the real star of the new detective drama was RH. It was RH’s first performing role, and quite a departure from his day job as assistant information manager for a professional body.

Given the proximity of Holy Island (the setting for the show) SS encouraged members of my running club to volunteer for walk-on parts. I was looking forward to starring in the scene when I would discover a clue in a lime green Croc.

To win my role, however, I had to fight two homeless women in the lower levels of a dark multi-storey car park. With the help of another amateur actor, who came to the rescue when he heard my screams, I managed to despatch this pair by bundling them into a gap in the car park wall. I then kindly referred my assailants to social services, other agencies and charities in the hope that they would soon find somewhere to live.
