This book is a must for anyone new to financial markets, and particularly to the City of London.
It describes the history of finance in the City and how the different markets came about, what they're about, and how government policy shaped the competitive and busy financial centre that it is now.
This book isn't an in-depth study of the markets, and its easy style will appeal to anyone wishing to gain an insight into what makes the City tick.
I read this book 3 years after I started working in financial IT, and I wished I'd read it much sooner.
