It had taken another hour for them to get there, and the day was starting to fade. Professor Wilson had been amazed to discover that he could actually get a signal for his mobile phone if he stood up above them on the shoulder of the mountain. He was talking animatedly to someone back in Edinburgh. Gunn was gazing into the valley in reflective silence. He turned suddenly towards Fin. ‘I got a letter from the Presbytery yesterday, Mr Macleod. Calling me to give evidence at Donald Murray’s trial, or whatever it is they’re calling it.’ Fin nodded. No doubt his would be waiting for him at home. And he wondered what he would say to those people who wanted to throw Donald Murray out of their Church. He closed his eyes and recalled the horror of that night in Eriskay when two men from Edinburgh had faced them with guns and the promise of death. And Donald had arrived like an avenging angel to take the life of one of them and save all the others. A man motivated by the threat to the lives of his daughter and granddaughter, his progeny, the only reason, perhaps, that God had put him on this earth.
