The delight of this volume is in its glib drawing of conclusions from data as if they were unique interpretations. It is reminiscent of Holmes remarking to Watson in A Study in Scarlet that "You have been in Afghanistan, I perceive." When Holmes explains that Watson is a medical type, has the air of a military man, has a sun tan, and has an injured arm, it is obvious that he has been wounded in Afghanistan. Unfortunately, Watson may have good posture because his mother imposed it on him, may have injured his arm in a fall from a carriage, and may have enjoyed the sun in Italy. There are many explanations for observables. Some are more delightful than others; unfortunately, delight is not an epistemological criterion. Speculations are not hard evidence. A guess is not a fact. Despite these criticisms, the book is wonderful beach reading and is therefore recommended.
