There's always something compelling about reading someone's account of getting themselves deeper and deeper into mortal trouble. Then add the racy dark humour that is peppered throughout the book as Nick Leeson looks back on his futile attempts to rectify his increasingly desperate trading situation, whilst those around him are oblivious to the impending disaster. The narrative cleverly reveals just enough detail to vividly depict the general atmosphere of things without being bogged down in flowery descriptions, helping to maintain a good pace.
This is a classic story of a classic dilemma - what to do if you (or someone you are responsible for) makes a serious mistake. Do you face the immediate consequences and come clean with those affected by the mistake, or do you work around it and try and remedy the mistake before anyone finds out, whilst risking making things even worse? Whatever the morals of the decisions Nick made in response to such a dilemma, one just can't help but empathise and be swept up in his predicament.
The fact that it all happened for real makes this book so much more gripping than some trashy corporate thriller. You are likely to finish it within days, if not in a single sitting as I did. And read it again only a few months later.
