The Last Days of Night

I started reading this book during the GVBR so its looking a bit tatty after 9 days of travel by truck. The characters are well known, Tesla, Bell, Edison, Westinghouse.  How they all came together to fight out a court room war between AC and DC is the story line from the point of view of the lawyer. The author Graham Moore said he used some licence to fit the story together but essentially it all happened and the General Electric and Westinghouse companies are still here to prove it. I think this book is to appear as a film soon.
