Miller watched Dr Buchan as he moved up the boat towards him, cupping Catriona's face in his big hand as he went past. He didn't look like the family doctor today, all relaxed in shirtsleeves and casual trousers. He stopped to ruffle Miller's hair and offer him another cheery grin. Miller liked Dr Buchan. He didn't feel scared when he had to go to the surgery. Dr Buchan was always nice to him. He'd brought him comics and sweets when he'd had chickenpox and measles. Anyway, he was a friend of Dad's, and Catriona was his daughter. So Dr Buchan had to be all right, didn't he?
