Although some are autobiographical, these essays, written periodically from the sixties through to the present, mainly present Watson's views, often radical, on the topical issues of the day: a fascinating journey through the development of molecular genetics. The writing is clear, to the point and very readable. But, apart from simply enjoying imaginary arguments with Watson over the controversial points he makes on using mice for medical research, the dangers of genetically manipulated organisms and the pros and cons of the human genome project (just three examples), I found myself planning how I could use the essays for discussion in tutorial groups at both under- and postgraduate levels. The text will not only inform and broaden student minds but also stimulate debate. I recommend it for the general reading list with which we encourage our students to expand their horizons. It also provides material for use in communicating science to the public.
