A strange book this. The main text is an authoritative and stimulating tour of the positive aspects of "psychopathy" using examples from research and the personal lifestyle of Andy McNab. As such there are useful and well made forays into the perils of vacillation and the rewards of instant gratification, and interesting they are too. But... oh dear Prof Dutton, what made you think you could hide your fanboy worship of Andy in a populist psychology book? From the first few superfluous addresses of Andy as "mate" to the repeated anecdotes of "what me and my mate Andy did next" I started to wonder if this book was some sort of coded love letter. The strongest impression is of a dyed in the wool nerd who has somehow become mates with the school hard case (who also happens to sell millions of books), and every chapter regales us with laddish talk, swaggering little adventures and the cold beers they chug down. What Andy and the respective wives must think is not recorded, but the lasting thought is that Prof Dutton, already in the shade of his acquaintance Mark Mindfulness Williams, has hitched his wagon to a star and written a good book spoilt by his obsession with "look at me with me well hard mate" .
