Dickon was already there,Digging hard,with the crow and a young fox beside him. ‘Have you seen the robin?’he asked Mary.The little bird was flying busily backwards and forwards as fast as he could,carrying pieces of dry grass. ‘He's building a nest!’whispered Mary.They watched the robin for a moment.Then Mary said, ‘I must tell you something.You probably know about Colin Craven,don't you?Well,I've met him,and I'm going to help him to get better.’
