The death knock, he believes that’s what they call it. That hard, fast knock that signals the beginning of the end of something for a family. When that knock came at Rupert’s door, on a miserable, wet January evening, the bare branches of the trees bending and swaying in the wind as rain began to lash at the windows, Rupert knew he would open the door to the police. He’d been waiting for the knock for three days. He knew what they would tell him, and his stomach had rolled as he pulled the door open, slowly, as if to delay the moment.

‘Mr Osbourne-Milligan?’ They’d stood there, grim-faced, before he’d nodded and let them into the house, and they’d told him that they’d found her car, that it was found not far from the Severn Bridge, with her purse and a card with a single word scrawled across it – ‘Sorry’ – on the passenger seat inside. That given her state of mind and previous history, they were in no doubt about what she had done.

Nothing has been the same since those two police officers stood on Rupert’s doorstep, with their serious faces and grave voices, and told him that his life was about to change forever. Everything is washed out, faded, blurred by a persistent tug of guilt every time he lets himself think of her. More so today, the day they held a memorial service in Caro’s name. Everything is over for Caro, she is at peace. He has to keep on going, guilt balanced on each shoulder.
