Madam, – As an expatriate living in New Zealand, I had the good fortune to see Mary Harney hard at work, carrying out her official duties in Auckland at the weekend. She sported what appeared to be a cast on her left arm. Somewhat ironic I thought, given the recent revelations from Tallaght hospital, and I couldn’t help but wonder how long it took for her X-ray to be reviewed. – Yours, etc,
