It is always a huge pleasure to hear from readers with comments, thoughts (and corrections!) on issues that catch your attention in my books or articles. All letters sent to me c/o my agents, PFD at 55 New Oxford Street, London WC1A 1BS will be answered.

All comments posted here will be read. As you can imagine, it is impossible for most authors to answer personally comments and queries from readers all round the world, but I will do my best to address as many as we can manage.

Later editions of all my past books have profited very much from readers’ kindness in pointing out errors in the first print, and I hope that tradition will continue in the future. Thank you and best wishes.
