Madam, – Following my letter (4th January) concerning the care of learning disabled people, I have received a disturbing anonymous letter. I would plead with the writer to make him/herself known to me as a matter of urgency. All correspondence of a “whistle-blowing” nature is treated with utmost care by me. But it is impossible to challenge abusive or unethical practices when the information is given anonymously. I would appeal to the person to take courage and contact me. – Yours, etc,
