Is this a book that you would read from cover to cover? The simple answer is no! It is a book that the reader would dip into every now and again to get the flavour of one of Sir Patrick's works. There is an appraisal of each of Sir Patrick's works contained within it. This book constitutes the first of two, or perhaps three volumes of appraisals of Sir Patrick's books. Why have I found it necessary to spread out his works across two or three volumes? For two reasons basically: firstly, Sir Patrick wrote around 200 books throughout his long life; secondly is the issue of book availability; all of Sir Patrick's books are now out of print, and, the earlier ones mostly, are only sporadically available from antiquarian booksellers. It is a great honour for me to have this first volume ready for publication for the centenary year of Sir Patrick's birth in 2023.
