There is not a shred of humor or feeling. As is fairly well written, it can be assumed that it is the intention of the author. What he wanted to convey by this? For this novel big budget but negative and without any recreation? Around heroin lucky, but mostly "sane", the lives of others in a particular dark madness. Their quest for recognition is described as a vain before the race, if not deadly hazardous. In the end, it gives a long but informative and disillusioned novel, despite some good parts, as William Boyd knows describe landscapes. As the action with this little dull and banal side which makes it particularly credible. This book could trigger controversy among ethologists downright ready to laugh and confirms the general impression, tragic, this book gives the scientific world. Having read other books on similar subjects (fictional or biographical adventures of scientists), I rank this one in the last row of the genre, despite the technical talent of the author.
